Preliminary Wound Healing Activity of Polyherbal Formulation Containing Cinnamon zeylanicum, Centella asiatica and Moringa oleifera

Abstract

In the present work, a polyherbal gel formulation for wound healing activity was developed using 70% methanolic extract of Centella asiatica leaves, methanolic extract of Cinnamomum zeylanicum Nees stem bark as well as oil of Moringa olifera seed. The developed formulation was evaluated for organoleptic parameters like colour, odour, texture and physicochemical parameters like a loss on drying (LOD), pH, viscosity, spreadability, skin irritation study, etc. In-vitro antibacterial activity of both the extracts and oil of M. oleifera was carried out against two pathogenic bacteria Escherichia coli and Staphylococcus aureus by disc diffusion assay using tetracycline as a standard. Apart from that, the wound healing activity of a polyherbal formulation was evaluated by an incision model on wistar rats. The results showed that the polyherbal formulation exhibited dark brown colour with a smooth texture and cinnamon-like odour. The gel showed 9% LOD, pH was found to be 7.5±0.3, viscosity was 4609.5± 13.44 cps at 10 rpm with spindle number 63, and spreadability was found to be 19.44±0.26 (g.cm/s), and no irritation was found on the healthy volunteer’s skin. In the wound healing activity, polyherbal did not affect the normal feed and water uptake. The wound did not show any pus formation throughout the treatment period. In the Planimetry assessment, wounds treated with polyherbal formulation showed a good score at the end of the treatment. Results showed that polyherbal formulation containing 70% methanolic extract of C. asiatica leaves, methanolic extract of C. zeylanicum stem bark as well as oil of M. olifera seed have good wound healing activity.
