Introduction
Wound healing is a complex biological process involving hemostasis, inflammation, proliferation, and tissue remodeling. Infection and excessive inflammation are among the principal factors responsible for delayed wound healing and chronic wound formation. Modern wound-care research emphasizes the importance of controlling microbial load and inflammation to promote tissue repair.1
Panchavalkala has been traditionally indicated for ulcers, burns, postoperative wounds, and non-healing wounds. The formulation is rich in tannins, flavonoids, phenolic compounds, and phytosterols that contribute to its therapeutic actions. Review studies have highlighted its effectiveness in various formulations, including decoctions, gels, creams, ointments, and wound washes.
Mechanisms of wound healing activity
Anti-inflammatory effects:
Persistent inflammation delays wound repair by prolonging tissue damage and preventing progression to the proliferative phase. The polyphenols and flavonoids present in Panchavalkala reduce inflammatory mediators and oxidative stress, thereby creating a favorable environment for healing. This action helps reduce edema, erythema, pain, and tissue destruction.2
Antimicrobial activity:
Microbial colonization and biofilm formation are major barriers to successful wound healing. In vitro investigations have demonstrated antimicrobial activity of Panchavalkala against wound-associated pathogens, including both Gram-positive and Gram-negative organisms. The tannin-rich bark extracts exert bacteriostatic and bactericidal effects, reducing microbial burden and minimizing the risk of infection.
Antioxidant and astringent actions
Oxidative stress contributes significantly to chronic wound pathology. Panchavalkala contains antioxidant phytochemicals that neutralize reactive oxygen species and protect newly formed tissues. Tannins further exert an astringent effect that decreases wound exudation, promotes wound contraction, and accelerates granulation tissue formation.
Promotion of tissue regeneration
Experimental studies suggest that Panchavalkala enhances fibroblast proliferation, collagen synthesis, angiogenesis, and epithelialization. These processes facilitate faster wound closure and improve scar quality during tissue remodeling.
Conclusion
Panchavalkala represents a scientifically supported Ayurvedic polyherbal formulation with significant wound-healing and infection-control potential. Its antimicrobial, anti-inflammatory, antioxidant, and regenerative activities address multiple pathological factors involved in chronic wound progression. Emerging evidence suggests that Panchavalkala-based formulations may serve as effective adjuncts in modern wound management. Further large-scale randomized clinical trials are required to establish standardized therapeutic protocols and strengthen the evidence base for its clinical application.3
