Development and Formulation of Herbal Products- A Veterinary Herbal Care Perspective

Abstract

The increasing demand for safe, non-toxic, and sustainable veterinary dermatological products has accelerated interest in herbal alternatives to conventional chemical- and antibiotic-based formulations. The present study focuses on the development and evaluation of an organic herbal veterinary soap formulated with oat milk (Avena sativa) and neem extract (Azadirachta indica), designed with a novel dual-layer/stripe-based active release mechanism. Oat milk, rich in ?-glucans and avenanthramides, provides soothing, moisturizing, anti-inflammatory, and barrier-repair properties, while neem extract contributes potent antimicrobial, antifungal, antiparasitic, and wound-healing effects. The formulation integrates an oat-based core for gentle cleansing and skin protection with neem-infused stripes to enable controlled and targeted antimicrobial release during bathing. The soap was prepared using veterinary-safe herbal oils and additives and evaluated through standard physicochemical and quality control tests, including pH determination, lather stability, total fatty matter (TFM), and saponification analysis. The formulated soap exhibited a skin-compatible pH range (6.0–7.5), satisfactory foaming stability, acceptable TFM values (55–75%), and minimal free alkali content, confirming its safety and suitability for animal skin. The synergistic combination of oat milk and neem extract offers a balanced dermatological approach that supports microbial control, inflammation reduction, and coat health without contributing to antimicrobial resistance. This formulation demonstrates strong potential for veterinary dermatological applications, MSME-scale production, and future patent-oriented product development.

Antimicrobial properties of herbal and other additives:

1. Coconut Oil

Coconut oil is widely recognized for its strong antimicrobial properties, primarily due to its high content of medium-chain fatty acids, especially lauric acid. When lauric acid enters biological systems, it converts into monolaurin, a compound known to disrupt the lipid membranes of various bacteria, fungi, and enveloped viruses. This mechanism weakens the integrity of microbial cell walls, leading to cell lysis.

In veterinary dermatology, coconut oil is increasingly used for treating minor skin infections, hot spots, and fungal dermatitis because of its ability to inhibit Staphylococcus aureus, Candida albicans, and certain gram-negative organisms. Additionally, its moisturizing properties help restore the skin barrier, making it both a therapeutic and supportive ingredient in herbal veterinary formulations.

2. Olive Oil

Olive oil contains potent bioactive molecules, including oleuropein, hydroxytyrosol, and oleic acid, all of which contribute to its antimicrobial benefits. Oleuropein exhibits strong activity against several pathogenic microbes by altering their cell membrane permeability and inhibiting essential microbial enzymes. Hydroxytyrosol, an antioxidant phenolic compound, also has broad-spectrum antimicrobial activity, particularly against bacteria involved in skin infections.

In veterinary products, olive oil helps reduce inflammation, heal wounds, and control bacterial colonization in pets, especially in cases of dermatitis and ear infections. Its  nature enhances skin hydration while enabling better penetration of other active herbal ingredients.

3. Neem Extract

Neem (Azadirachta indica) extract is one of the most powerful botanical antimicrobials used in both human and veterinary medicine. It contains key bioactive compounds such as azadirachtin, nimbidin, nimbin, and gedunin, which possess antibacterial, antifungal, antiviral, and antiparasitic effects. Neem works by inhibiting microbial replication, altering cell membrane function, and suppressing virulence factors such as toxins and biofilms. It is particularly effective against organisms like Staphylococcus aureus, Escherichia coli, Malassezia pachydermatis, and fungal dermatophytes.

In veterinary herbal care products, neem extract is commonly used in shampoos, sprays, and ointments for treating mange, ticks, fungal infections, and septic dermatitis due to its multi-targeted antimicrobial mechanism.

4. Castor Oil

Castor oil contains ricinoleic acid, a unique fatty acid responsible for its antimicrobial and anti-inflammatory activities. Ricinoleic acid disrupts microbial cell membranes, inhibits their metabolic pathways, and reduces prostaglandin synthesis, which helps alleviate inflammation associated with infections. Castor oil also inhibits the growth of several gram-positive and gram-negative bacteria, including Staphylococcus, Pseudomonas, and Proteus species.

In veterinary formulations, it is used to soothe irritated skin, prevent secondary infections, and support wound healing. Its viscosity offers protective coverage, making it beneficial in balms, ointments, and herbal antiseptic creams for animals.

5. Sodium Hydroxide (Saponified Form)

Although sodium hydroxide itself is not an antimicrobial ingredient, it plays a crucial role in soap formulation where it converts oils into saponified fatty acid salts. These soap molecules possess natural antimicrobial properties by disrupting microbial lipid layers and reducing surface tension, allowing mechanical removal of pathogens from the skin. Soap made using sodium hydroxide effectively eliminates bacteria such as E. coli, Staphylococcus, and fungal spores by breaking down their cell membranes.

In veterinary herbal care products, saponified oils help remove dirt, allergens, and microorganisms from animal fur and skin, enhancing overall hygiene while supporting the activity of other herbal extracts.

6. Oat Milk

Oat milk contains bioactive components like beta-glucans, avenanthramides, and polysaccharides that exhibit mild antimicrobial and strong anti-inflammatory properties. Avenanthramides inhibit microbial adhesion and reduce irritation associated with infections, making oat milk suitable for sensitive or inflamed skin. Although not a strong antimicrobial agent by itself, it helps improve skin barrier function and reduces colonization of harmful microbes by maintaining skin moisture and pH balance.

In veterinary products, oat milk is especially valuable for pets with chronic allergies, dermatitis, or dry skin conditions, where microbial imbalance often triggers secondary infections.

7. Aloe Vera Gel

Aloe vera gel is rich in anthraquinones (such as aloin and emodin), saponins, polysaccharides, and glycoproteins, all of which exhibit antimicrobial activity. Aloe interferes with bacteria by damaging their membranes and inhibiting DNA replication. Its antifungal properties help control common veterinary pathogens such as Candida and Aspergillus. Moreover, aloe vera promotes wound healing through fibroblast activation and collagen synthesis, making it highly useful in veterinary skin care. Its soothing, cooling nature reduces inflammation, itching, and microbial load, making it ideal for shampoos, sprays, and topical gels.

8. Lavender Oil

Lavender essential oil possesses powerful antimicrobial components like linalool and linalyl acetate, which are known to suppress bacterial and fungal growth. These compounds penetrate microbial cell membranes, leading to leakage of cellular contents and subsequent cell death. Lavender oil is effective against pathogens such as Staphylococcus aureus, E. coli, Candida albicans, and dermatophytes. It also reduces inflammation, calms irritated skin, and provides deodorizing effects. In veterinary herbal care, lavender oil is commonly included for its antimicrobial, anxiolytic, and wound-healing benefits, making it a multifunctional ingredient.

9. Shea Butter

Shea butter contains triterpene esters, catechins, and fatty acids such as oleic, stearic, and linoleic acids that show antimicrobial activity. These compounds inhibit microbial multiplication and help heal damaged skin. Shea butter also strengthens the epidermal barrier, preventing opportunistic microbes from entering wounds or inflamed regions. In veterinary products, it is used to  soothe dry patches, and prevent microbial colonization in cracked skin. Its occlusive and nourishing nature assists in repairing skin integrity, reducing susceptibility to infections.

10. Colloidal Oatmeal

Colloidal oatmeal is made of finely powdered oats rich in avenanthramides, flavonoids, phenolic acids, and saponins that collectively provide antimicrobial and anti-inflammatory effects. Avenanthramides inhibit microbial-induced inflammation, while phenolic compounds retard bacterial growth by disrupting cell membrane integrity. Colloidal oatmeal also helps maintain optimal moisture levels, reducing conditions that favor microbial proliferation. In veterinary dermatology, it is widely used in shampoos and moisturizers to treat allergic dermatitis, eczema, and secondary bacterial infections. Its gentle, soothing action makes it safe for long-term use in pets with chronic skin issue

• The stripe dissolves slower than the oat base, creating a sustained antimicrobial effect.
• Localized neem prevents excessive exposure on sensitive animal skin while still delivering therapeutic potency.
•  Dual-Mechanism Action, Oat core: Soothing, moisturizing, anti-inflammatory, Neem stripe: Strong antimicrobial & antiparasitic action. This combination provides a balanced dermatological effect.

IMPORTANCE OF OATMILK IN VETERINARY DERMATOLOGY AND ITS MICROBIAL ACTIVITY

Oat milk, a colloidal suspension derived from Avena sativa, has become an increasingly valuable ingredient in veterinary dermatology due to its broad spectrum of dermatological, microbiological, and barrier-supportive actions. Its significance extends far beyond basic moisturization, as oat milk is now recognized for its ability to modulate inflammation, restore epidermal integrity, support the skin microbiome, prevent pathogen colonization, and provide low-level antimicrobial activity functions that are critical in managing dermatological disorders in animals. Veterinary species such as dogs, cats, horses, cattle, goats, and small mammals frequently suffer from environmental irritants, parasite-induced dermatitis, fungal overgrowth, bacterial infections, and chronic inflammatory skin diseases. Because animal skin is more sensitive and physiologically different from human skin, harsh synthetic cleansers or antibiotic-based topicals often cause secondary problems such as dryness, microbiome imbalance, irritation, and antimicrobial resistance. Oat milk serves as a safe, gentle, and multifunctional natural alternative that supports overall skin health without disrupting the microbiome or contributing to resistance.

Biochemical Composition Underpinning Dermatological Benefits

Oat milk contains a unique combination of β-glucans, avenanthramides, saponins, lipids, amino acids, vitamins, and phenolic antioxidants, each contributing to its dermatological and microbial benefits.

• β-Glucans form a protective, moisture-retaining gel layer that adheres to the skin, promoting hydration, elasticity, and wound healing.
• Avenanthramides, exclusive to oats, provide powerful anti-inflammatory and anti-itch effects.
• Saponins offer natural cleansing and mild antimicrobial action.
• Lipids and ceramide-like molecules help rebuild damaged skin barrier layers.
• Phenolic compounds neutralize oxidative stress and inhibit microbial enzymes.

This biochemical richness allows oat milk to address multiple dermatological pathways simultaneously.

Importance of Oat Milk in Veterinary Dermatology

1. Anti-Inflammatory and Anti-Pruritic Effects

Inflammation is a central component of most veterinary skin disorders. Oat milk's avenanthramides inhibit inflammatory mediators such as:

• NF-κB
• COX-2
• IL-6
• TNF-α

This results in reduced redness, decreased heat and swelling, relief from scratching and irritation. This makes oat milk particularly beneficial for conditions like allergic dermatitis, flea allergy dermatitis, mange irritation, and chronic pruritus.

2. Skin Barrier Restoration

Animals frequently suffer barrier damage from Environmental factors, Parasites, excessive licking or scratching, harsh grooming products. Oat milk restores the barrier through:

• β-glucan film formation
• Ceramide-like lipid replacement
• Protein-supported keratinocyte regeneration
• A repaired barrier prevents further microbial invasion and moisture loss.

3. Deep Moisturization and Hydration

Oat β-glucans act as humectants capable of attracting moisture, retaining hydration for extended periods, preventing scaling and dryness. Hydrated skin is less prone to infections, lesions, and micro-tears.

4 .Wound-Healing Support

Oat milk accelerates tissue repair by stimulating collagen synthesis, enhancing epithelial cell migration, locking moisture in wound beds, protecting lesions from external contaminants. This helps in recovery from bite marks, abrasions, hotspots, and post-parasitic wounds.

Microbial Activity of Oat Milk in Veterinary Use

Oat milk is not a strong antibiotic but exhibits meaningful low-level antimicrobial, anti-adhesive, and microbiome-supportive activity. These are critically important because they do not induce antimicrobial resistance.

1. Mild Antibacterial Action

Oat milk inhibits growth of common pathogens such as:

• Staphylococcus aureus
• Staphylococcus pseudintermedius
• Streptococcus pyogenes
• E. coli

Mechanisms include mild disruption of microbial membranes by saponins, inhibition of bacterial enzymes by phenolic antioxidants, reduction of oxidative stress associated with infections, film-forming β-glucans creating an unfavorable surface for bacterial proliferation. This gentle antibacterial action supports recovery without harming beneficial flora.

2. Antifungal and Anti-Yeast Effects

Oat milk indirectly suppresses fungal growth by blocking fungal adhesion to the skin, maintaining moisture balance, providing anti-inflammatory relief from yeast-induced irritation. This makes it helpful in managing mild fungal infections, yeast dermatitis, and dandruff.

3. Anti-Adhesive Mechanism

β-glucans create a soft, protective film over the skin that Prevents bacteria and fungi from attaching, reduces biofilm formation, blocks the first step of skin infection. This mechanism is essential in preventing colonization by pathogens like Staphylococcus.

Oat Milk is a best alternative to Antibiotic-Based Dermatological Care

Oat milk provides:

• Non-antibiotic antimicrobial activity
• No risk of antimicrobial resistance
• Microbiome protection
• Gentle, natural skin healing
• Multimodal action (soothing + barrier repair + pathogen prevention)

Thus, oat milk is an ideal ingredient for regular veterinary skin care products like shampoos, soaps, sprays, and lotions.
