Review on Herbal Wound Healing Ointment

Abstract

Wound healing is a critical physiological process that restores the integrity of damaged skin tissue. Synthetic wound healing agents may cause side effects such as irritation, delayed healing, or microbial resistance. To overcome these challenges, herbal alternatives with traditional therapeutic value have gained interest. The present study aims to formulate and evaluate a herbal wound healing ointment using medicinal plant extracts such as guava (Psidium guajava) leaves, neem (Azadirachta indica), and aloe vera (Aloe barbadensis), known for their antimicrobial, anti-inflammatory, antioxidant, and astringent properties. The selected herbal materials were collected, shade-dried, and powdered. Extracts were prepared using appropriate solvents and incorporated into an ointment base made from beeswax and petroleum jelly. The formulation was evaluated for various physicochemical parameters, including color, odour, pH, spreadability, homogeneity, and stability under different storage conditions. Preliminary wound healing activity was assessed using an animal model (if applicable) or observational parameters like wound contraction and epithelialization time on a simulated wound. The herbal ointment showed favorable results, including reduced inflammation, faster wound closure, and minimal skin irritation when compared to a standard market formulation. This study concludes that the developed herbal ointment is effective for topical wound management and can serve as a safe, affordable, and eco-friendly alternative to synthetic wound healing agents. The formulation holds promise for further development and clinical.

Introduction

Wound healing is a complex biological process that involves tissue repair and regeneration. It is crucial for restoring the skin's integrity and preventing infections. Traditional medicine has long used herbal remedies to enhance wound healing due to their antimicrobial, anti-inflammatory, and regenerative properties. Herbal extracts like Aloe Vera, Turmeric, and Neem have been scientifically proven to aid in faster healing by reducing inflammation, promoting cell growth, and preventing microbial infections. Unlike synthetic formulations, herbal creams provide natural, chemical-free, and skin-friendly solutions for wound care. This project focuses on developing an effective herbal wound healing cream using natural ingredients. The formulation combines herbal extracts with a suitable base to ensure proper absorption, moisture retention, and antimicrobial protection for wounds.

BASEDONDEPTH

1. Superficial Wounds

• Involve only the epidermis (outer skin layer).
• Heal quickly with minimal care.

2. Partial-Thickness Wounds

• Extend into the dermis layer.
• Require moist healing environment; herbal ointments are effective here.

3. Full-Thickness Wounds

• Penetrate through the dermis into subcutaneous tissues.
• Healing is slow and may need surgical intervention.

BASED ON CLEANLINESS

1. Clean Wound

• Created under sterile conditions (e.g., surgical incision).
• Least chance of infection.

2. Contaminated Wound

• Contains dirt, bacteria, or foreign material.
• Needs cleaning and antimicrobial treatment.

3. Infected Wound

• Shows signs of infection-like pus, redness, warmth, swelling, and foul odor.
• Needs antibiotic or antiseptic treatment along with wound dressing.

BASED ON HEALING TIME

1. Acute Wound

• Heals in expected time (generally within 4 weeks).
• Example: surgical incisions, minor cuts.

2. Chronic Wound

• Takes longer to heal, may result from underlying conditions (e.g., diabetes, pressure sores).
• Requires continuous care and sometimes herbal formulations for skin regeneration.

BASED ON CAUSE IN CLINICAL PRACTICE

1. Pressure Ulcers (Bedsores)

• Caused by prolonged pressure on skin.
• Common in bedridden patients.

2. Diabetic Foot Ulcers

• Result from poor circulation and nerve damage in diabetics.
• Very slow to heal.

3. Venous or Arterial Ulcers

• Caused by poor blood circulation in legs.
• Often chronic and need specialized care.

WOUND HEALING AND ITS IMPORTANCE:

Wound healing is a biological process through which the skin and other tissues repair themselves after an injury. It is essential for maintaining the body's protective barrier, preventing infections, and restoring normal skin function. The healing process involves four key phases:

1. Hemostasis Phase - When a wound occurs, blood clotting (coagulation) happens immediately to stop bleeding. Platelets in the blood release clotting factors to form a protective barrier.

2. Inflammatory Phase - White blood cells (mainly macrophages and neutrophils) arrive at the wound site to destroy bacteria and remove dead cells. This phase often involves swelling, redness, and pain.

3. Proliferation Phase - New tissue begins to form -as fibroblasts produce collagen and keratinocytes regenerate the skin. Blood vessels are restored to supply oxygen and nutrients to the wound.

4. Maturation Phase (Remodeling Phase) - The wound strengthens as new collagen fibers organize, and the tissue structure is restored. This process can take weeks to months If a wound does not heal properly, it can lead to chronic wounds, bacterial infections, delayed recovery, and scarring. To promote faster healing and prevent complications, herbal medicine has been widely used as a safe and effective alternative to synthetic treatments.widely used as has been widely used as a safe and effective alternative to synthetic treatments.

TRADITIONAL USE OF HERBAL MEDICINE IN WOUND HEALING
