Role of Unani Formulation ‘Zaroor-E-Qawi’ in re-epithelialisation of the Chronic Wound: A Single Arm Prospective Clinical Study
Abstract: Background: Epithelialisation i.e. restoration of an intact epidermal layer is an essential criterion for wound healing. In fact, a wound which is not reepithelialised completely is not considered as healed one, no matter how perfectly the underlying dermal structures are restored. When the process of epithelialisation is compromised, impaired or delayed, it results in non-healing wound. Objectives: To assess the effect of the Unani formulation Zaroor-E-Qawi in the induction of …
