Integrative Therapies for Type 2 Diabetes Mellitus: A Systematic Review of Ayurvedic Interventions, Allopathic Standards and Novel Synergies

Simple analogy

• Insulin Deficiency = No key

The door is fine, but you don’t have the key to open it. Glucose stays outside cells → Type 1

• Insulin Resistance = Rusty lock

You have the key, but the lock is jammed. You need more and more keys. Eventually you run out of keys too → Type 2

OUTCOME:  Both lead to CHRONIC HYPERGLYCEMIA

1. Glucose can’t get into muscle/fat.
2. Liver keeps making more glucose.
3. Over time → Micro vascular + Macro vascular complications.

It matters for Treatment

• Deficiency : You replace insulin
• Resistance : You sensitize tissues with metformin, Thiazolidinediones (TZDs), exercise, Ayurvedic herbs and minerals,  weight loss, yoga, diet and reduce glucose production

Role of Pancreas, Liver, Muscle, Adipose tissue are given in the table below

Hence, Type 2 treatment targets all 4 organs e.g;

Metformin → Liver, TZDs/ Exercise → Muscle & Fat, Glucagon – like Peptide – 1 (GLP-1/ Sulfonylurea’s (SU) → Pancreas. 

Type 2 isn’t just “high sugar’. It’s 4 organs miscommunicating. That’s why the best management hits all 4 at once.

The 4 Organ Treatment Map is well explained below  

1. PANCREAS: Make enough insulin at the right time + stop excess glucagon.

2. LIVER: Turn off Gluconeogenesis and glycogen breakdown.

3. SKELETAL MUSCLE -Make muscle listen to insulin again.

4. ADIPOSE TISSUE - Stop fat from leaking FFA + fix hormones.

Combination therapy works better

Integration Model for Type 2 DM

To put it briefly, allopath quickly corrects the flaw. Long-term sensitivity is restored by AYUSH + Lifestyle.

The "hidden drivers" that link fat, insulin resistance, β-cell failure, and comorbidities are oxidative stress, inflammation, and gut macrobiotic.

Synopsis of Integrative Therapy  

The causes of oxidative stress, inflammation, and gut health are the focus of integrative therapy.

Type 2 diabetes complications

Over time, high blood sugar affects blood vessels, which are divided into two categories: micro-vascular and macro-vascular.

Chronic hyperglycemia and oxidative stress are major causes of micro-vascular problems because they harm capillaries, which are tiny blood vessels. For instance, the involvement of end-stage kidneys, nerves, and eyes. On the other hand, damage to big blood vessels, or arteries, like the heart, brain, or legs, is known as macro-vascular problems. Insulin resistance, dyslipidemia, hypertension, inflammation, and oxidative stress are major causes of this condition.

In their discussion of DM consequences, Ohiagu FO et al^[3] noted that hyperglycemia activates polyol, hexosamine, Protein Kinase C (PKC), Advanced Glycation End-products (AGEs), Cyclooxygenase (COX) and Lipoxygenase (LOX) pathways, which causes nephropathy, retinopathy, and neuropathy. Thus, inhibiting these enzymes helps avoid issues.

ALLOPATHIC MANAGEMENT:

There are various classes of allopathic drugs which act upon different vital organs such as pancreas, liver, muscle, adipose, kidney, gut:

1. Drugs that elevate Insulin or lower Glucagon:

    Drug Class:    

i. Sulfonylureas, such as gliclazide and glimepiride

ii. Meglitinidines, such as Repaglinide

iii. Dipeptidyl Peptidase- 4 inhibitors (DPP-4i), such as Sitagliptin and Vildagliptin

iv.Glucagon- like Peptide- 1 Receptor Agonists (GLP-1 RA), such as Semaglutide, Liraglutide, and Dulaglutide

2.  Drugs that decrease hepatic glucose production and raise sensitivity:

     Drug Class:

 i. Biguanides - example - Metformin

ii. Thiazolidinediones - Pioglitazone

3. Drugs that increase Urinary Glucose Excretion :  

    Examples:  Empagliflozin, Dapagliflozin, Canagliflozin

4. Drugs that impede the absorption of carbohydrate :

    Drug Class - .Alpha-glucosidase inhibitors, such as Acarbose, and Voglibose

5. Insulin :

Type: Basal – examples include Degludec and Glargine

 Prandial - Lispro, Aspart

 Premix - Combo basal + Prandial, such as 30/70, 50/50

ORGAN TARGET DRUG CLASSES

1. Pancreas – SU, GLP-1 RA, DPP-4i, Insulin
2. Liver - Metformin, GLP-1 RA
3. Muscle - Metformin, TZDs, Exercise
4. Adipose -TZDs, GLP-1 RA, SGLT2i
5. Kidney - SGLT2i
6. Gut / Brain - GLP-1 RA, DPP-4i, α-glucosidase inhibitors

The treatment algorithm can be summed up as follows:

1. Metformin + All T2DM Lifestyle

2. Regardless of HbA1c, add GLP-1RA or SGLT2i if you have Atherosclerotic cardiovascular Disease (ASCVD), Chronic Kidney Disease ( CKD) or Heart Failure (HF).

3. If the goal is not reached, add a second or third medication from a different class,     

    such as SU, DPP-4i, TZD, α-glucosidase, insulin.

Insulin and Analogs:

When β-cells fail or other drugs aren’t enough, insulin replaces the hormone.

Reasons for using Insulin in Type 2 DM:

1. After five to ten years, β-cell failure

2. Symptomatic hyperglycemia or HbA1c > 10% at diagnosis

3. Acute sickness, surgery, DKA, Hyperglycemic Hyperosmolar State (HHS) and pregnancy

4. Uncontrolled on two to three oral agents plus GLP-1 RA/SGLT2i

Insulin Types and Analogs:

1. Rapid-acting analogs: onset in 10 to 15 minutes, peak in 1 to 2 hours

2. Short-acting analogs: onset in 30 minutes, peak in 2 to 4 hours

3. Intermediate-acting analogs: onset in 2 to 4 hours, peak in 4 to 12 hours

4. Long-acting analogs: flat, no peak, one to two hours of onset

5. Ultra long analogs with a flat peak and an onset of one to two hours

6. Premixed: onset, two peaks, 10 to 30 minutes

More Recent Developments:

1. Ultra-rapid analogs that are closer to meals, such as Lispro-aabc and Faster Aspart

2. Intelligent insulin pens that monitor dosage, timing, and remind.

3. Weekly baseline injections of Icodec-1

4. Oral insulin is still undergoing testing and has not yet received approval.

Choosing Insulin vs. GLP-1 RA: Depending on the circumstances, a better option may be suggested as

1. HbA1c >10% + symptoms: Insulin                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       

2. GLP-1 RA obesity

3. ASCVD/CKD: GLP-1 RA or SGLT2i initially.

4. The cost of human insulin

5. Fear of weekly GLP-1 RA injections

    The deficit is treated with insulin. However, resistance is not resolved by it. Therefore, insulin + sensitizer + weight loss medication is the current T2DM treatment.

Efficacy and Clinical Guidelines:

Guidelines focus on three things i.e. HbA1c, weight and organ protection

Efficacy depends on baseline HbA1c. Higher starting HbA1c is equal to bigger drop.  

The American Diabetes Association (ADA), the American Association of Clinical Endocrinology (AACE), the Research Society for the Study of Diabetes in India (RSSDI) (2024 guidelines customized for India), and many other clinical guidelines are available.

The RSSDI-India 2024 Guidelines, which have been modified for India, are as follows:

1. First line: Metformin + Lifestyle + Early usage of DPP-4i, SGLT2i, GLP-1 RA

2. Cost and Access: Pioglitazone and SU are still commonly used.

3. Emphasis: At diagnosis, look for complications. Utilize FDCs to ensure compliance

4. Integrative: Recognize AYUSH, yoga, and diet as supplements.

Insulin-specific guidelines are advised in various circumstances when a patient is on insulin.

For example,

Significant changes to the 2024 Guidelines

1. Prioritize organ protection by selecting SGLT2i/GLP-1 RA for the kidney and heart rather than just sugar.

2. Weight is a target: in obesity, GLP-1 RA and SGLT2i are favored

3. Early Combo: Don't wait for metformin to stop working. If HbA1c is greater than 7.5%, start two medications.

4. De-intensification: To prevent hypoxia in the elderly and fragile, loosen the HbA1c target.

5. Continuous Monitoring: If on insulin or at low risk, CGM is advised.

Efficacy summary:

i) Maximum glucose reduction: Insulin + GLP-1 RA. SU. Metformin

ii) Maximum weight loss: GLP-1 RA > SGLT2i > Metformin

iii) Heart protection with metformin, SGLT2i, and GLP-1 RA

iv) SGLT2i, GLP-1RA, and ACEi/ARB kidney protection

v) Metformin, DPP-4i, SGLT2i, GLP-1 RA, and Lowest hypoglycemia.

vi) Metformin, SU, and human insulin are the least expensive.

No single medication is the best. Therefore, guidelines need to be both organ-centered and patient-centered.

Regular health examinations should be performed on all patients. The following Monitoring Schedule should be followed for the primary required check-up:

1. HbA1c should be checked every three months until the goal is reached, then every six months after that.

2. Kidney: Estimated Glomerular Filtration Rate (eGFR), Urine Albumin – to- Creatinine Ratio (UACR) at diagnosis, followed by annual.

3. Eye Exam: Each visit.

4. Blood pressure and cholesterol: at diagnosis, then annually.

5. Body Mass Index (BMI) and weight: Each visit.

The preferred allopathic treatment for keeping a diabetic patient's general health in good condition.

Allopathic preferable medication for maintaining the overall health of diabetic patient in good condition -

1. Organ Protection from Excess Glucose: Start SGLT2i/GLP-1 RA in ASCVD/HF even if HbA1c is 6.8%. This is the preferred allopathic treatment for keeping the general health of a diabetic patient in good shape.

2. Early Combination: If HbA1c > 7.5%, start two medications instead than waiting for metformin to fail.

3. Target weight: GLP-1 RA is favored in obesity

4. CGM: Suggested for anyone using SU or insulin  

The latest allopathic clinical guidelines for diabetes management emphasize a holistic Cardiovascular, Kidney and Metabolic (CKM) risk-reduction model rather than focusing solely on blood glucose control.

Gawde S. et al.^[4] created a pulsatile pellet-based Teneligliptin formulation that showed acceptable physicochemical characteristics and was able to accomplish time-controlled drug release.

Limitations and Adverse Effects:

Since no drug is flawless and has no side effects, the class-specific side effects and limitations are described.

In his research on diabetic retinopathy (DR), Bloomgarden Zachary ^[5] has demonstrated the advantages of blood pressure control and glucose control as well as the potential benefits of fenofibrate, RASi, and SGLT2i in improving DR.

There are five major issues to focus on:

A. Hypoglycemia - Low blood sugar

High-risk drugs: meglitinides, insulin, and SU.

Symptoms include tremor and sweating. Seizures and confusion

It is important because of adverse cardiovascular events, falls in the elderly, fear, and low compliance.

Mitigation: Instead, use GLP-1 RA, SGLT2i, DPP-4i, and Metformin. CGM + Education.

B. GI Effects 

High risk drugs -Metformin, GLP-1 RA, α-glucosidase inhibitors. Metformin - Lactate in gut

GLP-1 - delayed gastric emptying. Mitigation: Start low, go slow. Take with food. Extended -Release metformin

C. Lactic Acidosis                       

Medication: 3–10 metformin per 100,000 patient-years. Quite uncommon.

Risk factors include contrast, alcohol, sepsis, liver failure, and eGFR < 30.

Action: Stop 48h before/after contrast. Stop if creatinine increases.

D. Cost

Metformin costs Rs. 50 per month, SU costs Rs. 100 per month, and human insulin costs Rs. 500 per month.Mid: SGLT2i Rs. 2000–3000/month, TZD Rs. 300/month, DPP-4i Rs. 800–1500/month.GLP-1RA costs between Rs. 5000 and Rs. 15000 a month, while analogs cost between Rs. 3000 and Rs. 6000 per month.

Low serum vitamin B12 level is associated with longer duration and higher dose of metformin use as reported by Akinlade KS et al ^[6]

1. Over time Drug Resistance

What occurs: In T2DM, β-cell function decreases by 4-6% annually.

Drug: SU: Causes β-cell exhaustion. 5–10 years of secondary failure Metformin is a medication that can't stop insulin resistance from getting worse. TZD: Stopped weight gain and fluid intake. Insulin medication: resistance rises, dose continues to rise.

 Early combination therapy, weight loss, and the medication GLP-1RA, which preserves β-cells, are the solutions.

Additional long-term restrictions include:

1. Gaining weight exacerbates insulin resistance due to SU, TZD, and insulin

2. Organ toxicity: none significant, however canagliflozin increases the likelihood of TZD- 

    bone and SGLT2-ampulation.

3. Doesn't reverse the disease: All medications address hyperglycemia rather than the    

    underlying cause of insulin resistance.

4. Polypharmacy: The majority of patients take three to four medications, a statin, and an    

   ACE Inhibitor.

Choosing medications that provide efficacy, safety, organ protection, and weight loss with the fewest possible adverse effects is the modern strategy in 2026. For high-risk patients, metformin, GLP-1 RA, and SGLT2i are thereby becoming the standard.

Under its Global Diabetes Compact and five Global Diabetes Targets for 2030, WHO is monitoring diabetes. According to the WHO, diabetes is one of the main causes of death and shortened life expectancy. The largest groups that WHO emphasizes

1. Increasing cases: four times higher

2. Significant undiagnosed burden: 1 in 2 individuals are unaware that they have it

3. Inequity: Low-income nations are more severely affected.

4. Urgent action on diagnosis, treatment, and prevention is required by 2030.

Old DM drugs like insulin, metformin, tolbutamide, glipizide are being replaced by newer, more potent drugs with longer action, fewer side effects and better glucose control. This is detailed by Elkhalifa et al ^[7]

AYURVEDIC PERSPECTIVE ON DIABETES

In Ayurveda, Diabetes is referred as  "Madhumeha," which means "honey-like urine."

1. Root cause in Ayurveda :

In Ayurveda, diabetes is correlated with  "Prameha," specifically Madhumeha.

Principal causes:

a) Diet: Overindulgence in processed, sugary, fatty, dairy, and grain foods

b) Lifestyle: Stress, inactivity, sleeping during the day, and sitting all day.

c) Dosha imbalance: In chronic situations, Kapha predominates first, followed by   

            Pitta and Vata.

d) Weak Jatharagni, poor digestion, the production of Ama toxins, and blocked channels

According to Ayurveda, Modern Type 1DM is Vata Madhumeha and Modern Type 2DM is Kapha + Pitta + Prameha.

2. Ayurvedic Therapy :

"Nidan Parivarjan" is an Ayurvedic treatment that eliminates causes, balances doshas, enhances agni, and detoxifies. 

1. Diet: For diabetic patients “Eating the Right food in Right amount and Right times” is important. Following are the recommended Diet but not limited:

       Fibrous food recommended to diabetic patients;

Fiber is the best medicine from food - It slows glucose absorption, improves insulin sensitivity and feeds good gut bacteria.

• Best Cereals:- Yava / Barley 17g fiber/100g, Oats-Beta-glucan fiber, Ragi,Jowar Bajra, Brown Rice, Dalia, Whole wheat with bran.
• Fiber rich Pulses: - Chana- 17g, Rajma-13g, Whole Moong- 12g,whole Masoor Kulthi/ Horse gram , Lobia.
• Vegetables ( 300-400g daily):- Highest Fiber - Karavellaka/ bitter gourd, Bhindi, Lauki, Patola, Methi bhaji, Broccoli, Cabbage, Cauliflower, Drumstick leaves.
• Fruits (With skin):- Guava- 5.4g, Pear, Apple, Orange, Papaya, Jamun, Ber, Pomegranate, Avocado.( Always eat with skin where possible). Avoid fruit juice as fiber is removed.
• Seeds / Nuts :- Flax-seed / Alsi -27g fiber - Roast - 1 Spoon daily, Chia seeds - Soak 1 spoon in water, Methi seeds - Soaked overnight water, Sesame, Pumpkin seeds, Almonds, Walnuts.
• Eating salad 15min BEFORE meal- reduces post-meal glucose spike by 30-40%- It is proven in Foodomics studies.

Curd known as Yogurt : Since unsweetened plain curd has low Glycemic Index - Between 14 to 36, it digests slowly and prevents rapid spikes in blood sugar after meals. The high content of protein in curd slows down absorption of carbohydrates, preventing sudden spikes in blood sugar, feel full for longer while maintaining stable energy levels. It is rich in Calcium and contains healthy fat. It supports weight management, improves digestion and boosts immunity

As per the write-up dated 5^th December 2024 in DIABETIC AND ENDOCRINOLOGY Most diabetic individuals can safely enjoy ½ to 1 cup (approximately 100–200 grams) of curd daily, depending on calorie intake and blood sugar control. Always monitor your post-meal sugar levels and make dietary adjustments as needed.

Avoid high- carbohydrate, starchy foods and sugary drinks. Also, limit fried foods, food high in sodium, and alcohol.

Maqsood S et al^[8] reported A new Approach Foodomics in Diabetes management. Foodomics integrates genomics, proteomics and metabolomics to study interaction of food bioactives with human metabolism in T2DM. It helps identify biomarkers, dysregulated pathways and role of gut microbiota in insulin resistance. This enables personalized, nutrition-based interventions for better glycemic control and prevention of complications. Polyphenols and dietary fibers show therapeutic potential for improving insulin sensitivity. 

2. Lifestyle - (Vihara) :

"Exercise: Surya Namaskar, Ardha Matsyendrasana, Mandukasana for pancreas, and a daily 45-minute walk or yoga are the greatest remedies for overall health. Sleep: Go to bed early and don't sleep during the day. Stress: Pranayama and meditation.

3. Herbs - (Dravya) :

Common herbs improve insulin sensitivity, slow down carbohydrate digestion, and boost pancreatic function to help control blood sugar levels.

While spices and other herbs like Cinnamon, Haldi, Garlic and Ginger, Amla, and Vijaysar are antioxidants and support the pancreas, the main anti-diabetic herbs include Jamun, Karela, Methi, Gurmar, and Neem.

Modak Manisha et al ^[9] summarized various Indian herbs and herbal formulations for the treatment of Diabetes,whereas, Tarle R et al^[10] designed, developed In-Vitro characterization and highlighted the importance of standardization of products. Tran N et al. ^[11] examined the pharmacological properties and active ingredients of plants used to treat diabetes in order to guarantee the quality. Additionally, morphological information from each species' V-herb database was used to identify plants.

Many natural herbs and spices show anti-diabetic activity, hence can be used in the formulation in appropriate proportion to get positive results.

1. Jamun (Syzygium cumini): The pulp and seeds of Jamun can help reduce blood sugar.  Jamboline, which is found in seeds, prevents starch from rapidly becoming sugar. The fruit has a low glycemic index of roughly 25, which means it raises blood sugar very slowly. High anthocyanin and polyphenol levels shield cells from harm caused by high glucose. Active substances help the body use insulin more effectively.

Fig 1. Jamun

2. Karela - Bitter Melon (Momordica charantia): helps the cells absorb glucose by acting as insulin. It has active ingredients including vicine, charantin, and p-insulin, an insulin-like peptide that increases insulin production, improves glucose uptake, and slows carbohydrate absorption in the gut's. Aids in preventing harm to pancreatic beta cells.

Fig 2. Karela

3. Methi - Fenugreek (Trigonella foenum-graecum): packed with soluble fiber. The seeds help decrease fasting blood sugar and slow down the digestion of carbohydrates.Soluble fiber and bio-active substances such as trigonelline and 4-hydroxyisoleucine are responsible for the anti-diabetic action. It decreases blood lipids, enhances insulin sensitivity, and lowers blood sugar enables the appropriate utilization of glucose by body cells by activating signaling pathways such as PI3K/Akt. Reduces oxidative stress and protects pancreatic beta cells from harm.

Fig 3. Methi

4. Gurmar - (Gymnema sylvestre): Known as the "sugar destroyer." It’s leaves may promote the synthesis of insulin and aid in blocking sweet taste receptors.Gymnemic acids temporarily block sweet taste perceptions and lessen sugar cravings by binding to sweet receptors on taste buds. It prevents abrupt rises in blood sugar following a meal by slowing down the small intestine's absorption of glucose.It may aid in the regeneration or repair of insulin-producing beta cells and stimulate the pancreas to release more insulin. It enhances the body's cells' utilization of glucose and fat processing. Bhatt S and Sharma N ^[12] in their article have discussed possible mechanism on how gurmarin helps manage diabetes and also discussed the plant tissue culture methods to enhance gymnemic acid production.

Fig 4. Gurmar

5. Neem (Azadirachta indica): Compounds in neem leaves, bark, and seeds can improve insulin sensitivity, reduce oxidative stress, and help the body use glucose better. It helps the pancreas release more insulin.Helps body tissues take in sugar from the blood.Lowers cell damage from high sugar levels using antioxidants.Active compounds like nimbin, nimbidin, and quercetin play a major role.

Fig 5. Neem

6. Chirayata (Swertia chirata): Swerchirin, mangiferin, and swertiamarin are among the active phytochemicals that give Chirayata its notable antidiabetic and antihyperglycemic properties. According to research, it improves insulin signaling, lowers blood glucose, and increases glucose tolerance. Swerchirin is a strong xanthone that has been extracted from the plant and is known to directly decrease blood sugar.          Dey Pinaki et al ^[13] have explained all valuable constituents and therapeutic potential of Swertia chirata along with associated pharmacological property.

Fig 6. Chirayata

7. Bichu buti (stinging nettle or Urtica dioica): It has the potential to prevent diabetes by lowering blood sugar, simulating the effects of insulin, and promoting the health of pancreatic cells. Plant compounds may enhance the absorption of glucose and lessen metabolic stress in general. Plant extracts have the potential to lower high blood glucose levels. Insulin Support: Active substances can boost the body's natural synthesis of insulin It helps lower oxidative stress linked to diabetic complications.

Fig 7 . Bichu - Buti

8. Gulwel - Giloy (Tinospora cordifolia): Madhunashini- “Destroyer of sugar” uses a variety of pancreatic and extra pancreatic mechanisms to assist control blood

      glucose levels mechanisms.Alkaloids, tannins, cardiac glycosides, flavonoids, saponins and steroids all these phytoconstituents have antidiabetic role. Antidabetic activity of T.cordifolia is well illustreated by Gupta A et al ^[14]

Fig 8 . Gulwel

9. Cinnamon : This popular spice lowers blood sugar levels by enhancing your body's reaction to insulin.Cinnamon's active polyphenols imitate insulin and slow down the digestion of carbohydrates in the gut, but human trials have yielded conflicting results, and it is not a substitute for conventional diabetes drugs.Alpha-glucosidase and pancreatic amylase are two intestinal enzymes that cinnamon slows down to lessen post-meal sugar increases.By slowing down stomach emptying, it helps avoid sharp spikes in blood sugar.High concentrations of coumarin, which can damage the liver in excess, are found in cassia cinnamon.  Ceylon ("true") cinnamon has low coumarin and is safer for regular use.Daily amounts ranging from 1 to 4 grams (about 0.5 to 1 teaspoon).

Fig 9. Cinnamon

10. Haldi - Turmeric (Curcuma longa): Curcumin, a primary curcuminoid and a naturally occurring polyphenol, is what gives turmeric (Curcuma longa) its antidiabetic properties. Through many cellular pathways, it aids in the reduction of blood sugar and the fight against insulin resistance. Enhances total insulin sensitivity and reduces cellular resistance. Reduces the liver's synthesis of glucose and increases the absorption of glucose by cells. Suppresses inflammatory cytokines that harm beta cells, such as TNF-alpha. Reduces oxidative stress, which is associated with problems from diabetes. Enhances the ability of the pancreatic beta cells to secrete enough insulin. In order to increase absorption and therapeutic efficiency, natural curcumin is frequently combined with piperine (black pepper extract) or prepared into bio-enhanced/nanoparticle formulations due to its low bio-availability.

Fig.10 Haldi

11. Daruhaldi (Berberis aristata): Berberine improves the way body cells react to insulin, facilitating the effective absorption and use of glucose. Also assists in activating pancreatic beta cells to enhance natural insulin production. It helps lower blood glucose levels, improve metabolic health, and manage diabetic complications.                               Berberine has gained attention as a supplement that can help with a number of disorders, including obesity and PMOS, according to a June 11, 2025, article in Health problems / diabetes and Endocrinology, When treating Type 2 diabetes, it is as effective as or even more effective than metformin. Berberine, however, takes around three months to start working. Metformin acts considerably more quickly. The full effects of metformin often take four to five days to manifest.                 

Fig11. Daruhaldi

12. Garlic (Allium sativum) and ginger (Zingiber officinale): The active chemicals found in ginger (Zingiber officinale) and garlic (Allium sativum) reduce oxidative stress, lessen inflammation, and improve insulin sensitivity. Additionally, their active ingredients reduce oxidative stress and guard against kidney and liver issues associated with diabetes.Both plants exhibit insulinotropic effects, which cause the beta cells in the pancreas to release more insulin.Gingerols enhance the absorption and clearance of glucose in adipocytes and insulin-responsive peripheral tissues. Ginger and garlic slow down the absorption of glucose by controlling the enzymes that break down carbohydrates.Frequent use lowers hemoglobin A1c (HbA1c) levels and fasting blood glucose.They increase high-density lipoproteins (HDL) and lower high levels of triglycerides, total cholesterol, and low-density lipoproteins (LDL). In diabetic organs, their abundant phenolic and sulfur compounds lessen oxidative stress, lipid peroxidation, and cellular toxicity. Oral administration of the ginger extract resulted in significant reduction of hyperglycemia, the diameter of the retinal vessels and vascular basement membrane thickness.

Fig.12. Garlic -Ginger

13. Aamla ( Emblica Officinale): This substance is packed with hydrolyzable tannins, such as corilagin, gallic acid, ellagic acid, and β-glucogallin, which scavenge free radicals and contain trace minerals like chromium believed to improve insulin sensitivity and aid carbohydrate breakdown. Its high antioxidant capacity, particularly from vitamin C, protects pancreatic beta-cells from oxidative damage and inflammation. It reduces postprandial blood sugar spikes by inhibiting carbohydrate-digesting enzymes such as aldose reductase and α-amylase, enhances glucose absorption pathways (e.g., AMPK activation) in skeletal muscles, and inhibits hepatic glucose synthesis. Additionally, it decreases markers of pancreatic inflammation, helps maintain or increase blood insulin and C-peptide levels, and improves lipid profiles by increasing healthy HDL cholesterol while decreasing triglycerides, LDL, and total cholesterol.

Fig13. Aamla

14. Vijaysar (Pterocarpus marsupium): Vijaysar exhibits potent anti-diabetic effects by reducing fasting blood glucose levels, enhancing insulin sensitivity, and protecting pancreatic beta cells from oxidative stress. Its active compounds, such as epicatechin, pterostilbene, and marsupsin, function similarly to traditional glucose-lowering medications by increasing natural insulin secretion through the protection and repair of pancreatic cells. Additionally, Vijaysar slows intestinal sugar absorption and carbohydrate breakdown, reduces oxidative stress-induced tissue damage, and lowers levels of harmful cholesterol and blood lipids, contributing to improved metabolic health in individuals with type 2 diabetes.

15. Paneer Doda (Withania coagulans): Paneer Doda exhibits anti-diabetic properties by preserving pancreatic beta cells, increasing insulin sensitivity, and enhancing glucose utilization. It improves the body's ability to use blood sugar and metabolize carbohydrates, potentially aiding in the maintenance or repair of insulin-producing beta cells in the pancreas. Additionally, Paneer Doda slows the absorption of sugar into the bloodstream, helping to curb sharp glycemic fluctuations i.e keep the blood sugar levels relatively stable preventing them from spiking too high or crashing too low after eating..

Fig15. Paneer Doda

16.  Kodtumba , bitter apple (Citrullus colocynthis): 

Demonstrates notable hypoglycemic (blood sugar-lowering) action in both clinical and laboratory research. However, the plant must be handled very carefully and should never be eaten raw or in uncontrolled amounts because it naturally contains hazardous, extremely irritating substances. Fruit pulp and seed extracts have been shown to dramatically lower fasting blood sugar (FBS) levels, according to research published on websites like Pub-Med. Clinical investigations have demonstrated that a significant reduction in mean HbA1c levels can result from controlled, low-dose daily administrations (e.g., 125 mg) over a two-month period. Saponins and flavonoids are examples of active substances that stimulate the pancreatic beta cells, causing them to release more insulin.  Kodtumba contains cucurbitacins, which are highly toxic chemicals that severely irritate the stomach and bowel.In large doses, it can cause severe diarrhea, vomiting, stomach cramps, and internal bleeding. Due to these risks, it was banned for unsafe over-the-counter use by the US FDA.

Fig16. Kodtumba

Benefits and limitations of C. colocynthis is provided in details by Li QY et al ^[15]. 

17. Aam Guthli (mango seed kernel) ( Mengifera indica) Mangiferin exhibits significant anti-diabetic activity by increasing insulin sensitivity, lowering HbA1c, and reducing fasting blood glucose levels, as demonstrated by scientific research. It inhibits digestive enzymes such as α-amylase and α-glucosidase, which slows carbohydrate digestion and reduces post-meal blood sugar spikes. Bioactive substances in Mangiferin stimulate muscle and fat cells to absorb glucose by promoting insulin release from the pancreas and upregulating genes like Glut4, Irs1, and P13k. Additionally, it suppresses hepatic glucose production during fasting by decreasing the expression of key liver proteins, such as glucose-6-phosphatase. Identified as a major active compound, Mangiferin plays a crucial role in these effects as reporded by Senthilkumar et al ^[16]. Moreover, its high content of flavonoids and polyphenols provides strong antioxidant protection, safeguarding pancreatic β-cells from oxidative damage and preventing cell death.

Salacia plant species (Salacia reticulata and Salacia oblonga) : By lowering post-meal blood glucose, lowering HbA1c, and enhancing insulin sensitivity by inhibiting intestinal carbohydrate-metabolizing enzymes, two species of Salacia plants—Salacia reticulata and Salacia oblonga—show notable anti-diabetic action. In human studies, it has been demonstrated that salacia extracts lower plasma glucose ^[17]. When given to individuals with type II diabetes, aqueous extracts successfully regulate blood glucose levels without causing side effects.Strong natural sulfonium ions that competitively block α-glucosidase in the intestinal tract are bio-active substances such as salacinol and kotalanol. It contains mangiferin, a polyphenol that helps control metabolism and has antioxidant qualities, also slows down the conversion of complex carbs into glucose and reduces postprandial glucose spikes by blocking α-glucosidase and α-amylase. It helps to control lipid profiles (lowering cholesterol and triglycerides) and activates cellular pathways like AMPK. According to research on animals, root extracts may help preserve and replenish insulin secretion and pancreatic beta-cell activity. Salcia reticulata Fig. 18a and 18b. Salcia oblonga.

20. Sahjan (Moringa oleifera) : includes plant compounds such quercetin, chlorogenic acid, and isothiocyanates that have anti-diabetic properties. These active substances slow down the body's absorption of sugar after a meal, assist reduce blood sugar, and enhance how cells use insulin. Many scientists have already worked on extracts of Moringa oleifera. ^[18]. This controls the blood glucose or insulin level and protects against organ damage under sustained condition.

21. Tulsi (Ocimum sanctum or Ocimum tenuiflorum) : significantly reduces oxidative stress, improves insulin production, and lowers blood glucose levels during fasting and after meals. Eugenol, caryophyllene, and ursolic acid are examples of bio-active substances that increase the amount of insulin released by pancreatic beta cells. High levels of flavonoids and polyphenols lessen oxidative cellular damage, which is frequently connected to insulin resistance.

24. Peepal leaves (Ficus religiosa):The hypoglycemic effect is aided by the presence of several flavonoids and phytosterols such β-sitosterol-D-glycoside. Phenolics in the tree parts assist in reducing carbohydrate breakdown and oxidative stress.

25. Sadabahar , Periwinkle (Catharanthus roseus) :  has anti-diabetic properties mainly because of bioactive substances such as vincamine, vindoline, and other indole alkaloids. By promoting cellular glucose consumption, bolstering pancreatic beta-cell function, and boosting insulin control, these active substances help lower blood glucose levels. Active alkaloids assist control hyperglycemia and reduce blood sugar levels.

However, before attempting any new herbal supplement, a doctor's consultation is required for safety reasons in order to eliminate a few negative effects brought on by herb interactions. For example, combining fenugreek and bitter melon with conventional diabetes medications or insulin can cause your blood sugar to drop too low. Also taking very high doses of certain herbal extracts can cause stress on the liver or kidneys.

4. Minerals used :

The correlation of diabetes and an imbalance in metal makes metal-based therapy as an attractive proposition.^[20] Certain minerals are essential for cellular sensitivity, insulin production, and glucose metabolism, including magnesium, chromium, zinc, Vanadium, selenium, and manganese.  Deficiencies can worsen insulin resistance, while maintaining adequate levels through diet or targeted supplementation supports better blood sugar control and lowers the risk of diabetic complications.

• Magnesium:  is an essential component for the metabolism of carbohydrates and aids in the correct binding of insulin to cell receptors. Elevated blood glucose levels lead to increased magnesium excretion in the urine, often resulting in a cycle of insufficiency that exacerbates insulin resistance
• Chromium: Enhances the body's cells' ability to react to the hormone by amplifying the insulin signal

• Zinc:  Essential for the pancreatic beta cells to properly store, synthesize, and secrete insulin.Standard textbooks of Ayurveda recommend Jasada bhasma - Jasat or Zinc based bhasma as the treatment of choice for diabetes.^[21] Taking inspiration from the fact that bhasmas contain submicronic or nanoparticles that enhance bioavailability, metal based nanomedicines can be developed for diabetes.

• Selenium and Manganese: are parts of antioxidant enzyme systems that save pancreatic cells from oxidative damage.

• Vanadium:

• Shows insulin-mimetic properties in experimental studies.
• Reduces high blood glucose levels.

5. Classical Formulations :

Various forms of formulations with single / multi herbs are available, such as tablets, capsule, granules, churna, juices and so on.

Dr. Narendra Bhatt ^[22]  has taken special efforts to develop “Evidence - validation-Acceptance [EVA] “ model for clinical studies in Ayurveda. The significance of EVA model lies in the possible matching of substance, the therapeutic intervention with that of the dysfunction and the optional choice of the most appropriate biological model for precise investigational parameters.Eva model as exemplified addresses the issues in clinical studies in ayurveda and could be used for new drug discovery.

6. Panchakarma Detox : 

This method can be used for early-moderate Kapha types, such as Vamana (therapeutic vomiting to lower kapha), Virechna (purgation), Basti (enema), or Vata type (removing Ama and opening channels).

7. Modern Medicine and Ayurveda :

In addition to modern medications like insulin and metformin, Ayurveda offers recommendations for bettering lifestyle, preventing complications, and supporting metabolism. According to Ayurveda, diabetes is a metabolic and lifestyle disease that begins with kapha buildup and poor digestion. Therefore, to avoid difficulties, one should concentrate on diet, daily routine, herbs, detox, and stress management. Ayurveda can be utilized as supportive therapy, and it is advised that doctors perform routine kidney, eye, and HbA1c tests.

COMPARISON of ALLOPATHIC and AYURVEDIC / OTHER TREATMENTS:

Thus, "Integrative diabetes care" is promoted by WHO and AYUSH.

1. Allopathy is recommended by the Common Model for acute high blood sugar, Type 1 diabetes, HbA1c > 9%, and sequelae.

2. Ayurveda for the treatment of pre-diabetes, type 2 diabetes, weight, stress, neuropathy, and lifestyle modification.

3. Together: Under supervision, the patient is taking metformin, following a diet, using herbal remedies, and doing yoga.

Allopathy can be compared to a fire extinguisher, which is quick, strong, vital in emergency situations, and requires strict management.

Ayurveda = Fire Prevention System: Slower, improves food, habits, and metabolism to prevent the "fire" from starting or getting worse.

The majority of persons with Type 2 diabetes benefit most from allopathic management, an Ayurvedic lifestyle, and the use of certain herbs while keeping doctors, Vaidyas, and practitioners informed.

On Regulatory point of view,we are not allowed to make claims that "cures diabetes."

Permitted " For blood sugar support and Madhumeha management ".

YOGA:

By reducing stress hormones, increasing blood circulation, and enhancing insulin sensitivity, yoga aids in the management of diabetes. Poses that are beneficial include:

• Bow Pose (Dhanurasana): Lying on your stomach, hold your ankles and lift your chest up to stretch the belly area and stimulate the pancreas.
• Half Spinal Twist (Ardha Matsyendrasana): Sit and twist your torso to gently squeeze the abdominal organs.
• Seated Forward Bend (Paschimottanasana): Sit with legs straight, reach for your toes to calm the mind and stretch the back.
• Legs-Up-the-Wall (Viparita Karani): Lie on your back with legs resting up against a wall to relax and improve blood flow.
