Guduchi–Saindhava Lepa in the Management of Sadyovrana: A Critical Narrative Review of Classical Rationale and Contemporary Evidence

Abstract

Wound healing is a complex and coordinated physiological process involving overlapping phases of hemostasis, inflammation, proliferation, and remodeling. In Ayurveda, disruption of tissue continuity is described as Vrana, and wounds resulting from external causes are broadly classified under Agantuja Vrana. Sadyovrana, referring to acute or freshly occurring wounds, requires timely management to facilitate wound cleansing, control inflammation, promote tissue repair, and prevent complications. The present critical narrative review evaluates the classical basis and contemporary scientific evidence concerning the role of Guduchi–Saindhava Lavana Lepa in the management of Sadyovrana. Relevant classical Ayurvedic literature, including Charaka Samhita, Sushruta Samhita, Ashtanga Hridaya, and selected commentaries and regional sources such as Vaidya Manorama and Dhara Kalpa, was reviewed along with contemporary biomedical literature concerning Guduchi [Tinospora cordifolia (Willd.) Hook.f. & Thomson] and Saindhava Lavana. Classical references provide a rationale for the use of Guduchi and Saindhava in wound-related conditions, particularly in the context of Vrana Ropana and Vrana Shodhana. Contemporary studies on Guduchi report anti-inflammatory, antioxidant, immunomodulatory, antimicrobial, and tissue-reparative activities, whereas evidence specifically evaluating the wound-healing effects of Saindhava Lavana is comparatively limited. Importantly, no in-vitro, pilot, in-vivo, or clinical studies specifically evaluating the combined Guduchi–Saindhava Lavana Lepa in Sadyovrana were identified in the literature reviewed. Therefore, the proposed therapeutic benefits of the combination are currently based on a classical rationale and on extrapolation from evidence concerning the individual drugs, rather than on direct validation of the formulation. The review highlights the gap between classical therapeutic rationale and contemporary experimental evidence and indicates the need for systematic experimental and clinical studies to establish the safety, efficacy, formulation parameters, mechanism of action, and or potential effects of the combination.
