Effects of oral and topical administration of an alcoholic extract of C. asiatica on rat dermal wound healing was studied. The extract increased cellular proliferation and collagen synthesis at the wound site, as evidenced by increase in DNA, protein and collagen content of granulation tissues. Quicker and better maturation and crosslinking of collagen was observed in the extract-treated rats, as indicated by the high stability of acid-soluble collagen and increase in aldehyde content and tensile strength. The extract treated wounds were found to epithelialise faster and the rate of wound contraction was higher, as compared to control wounds. The results show that C. asiatica produced different actions on the various phases of wound repair.
