According to the abstract released by the Intellectual Property India: "The present invention is related to a composition and method for preparation of neem and turmeric based wound healing spray based on natural extracts of Neem (Azadirachta indica) and Turmeric (Curcuma amada and/or Curcuma longa). The formulation comprises 1.50 g Neem extract, 1.50 g Turmeric powder, 2.00 g Hydroxypropyl Methylcellulose (HPMC, 5 cps), 0.05 g Sodium Benzoate, and 100 ml purified water. The preparation involves shade drying and milling of Neem leaves and Turmeric rhizomes, extraction of Neem in hot aqueous medium, and dispersion of both extracts into an HPMC solution under continuous stirring to obtain a homogeneous suspension, filled into spray containers. The optimized formulation exhibits desirable physicochemical properties including clear appearance, stable pH (6.45-6.48), viscosity (42-46 cP), uniform spray pattern, and spreadability. Antimicrobial studies confirmed complete inhibition of Staphylococcus aureus, while wound healing experiments demonstrated accelerated epithelialisation and 45% average healing compared to 17.5% in untreated controls."
