OA02.04. Wound healing property of Kanchanara [Bauhinia variegata Linn] - An experimental study.

PURPOSE: Wound a clinical entity, is commonly seen as a result of various etiological factors like trauma etc. Kanchanara a plant origin drug. Many of the Nighantu's have mentioned vrana shodhana and vrana ropana properties of Kanchanara. Hence present study of evaluating wound healing property of Kanchanara bark in the form of churna and ointment [sikta taila base] preparations has been taken up. METHOD: Albino rats were the experimental model. 36 albino rats were selected and divided into 6 groups of 6 rats each. 3 groups were used for excision wound model and remaining 3 groups were used for incision wound model, one group being served as the control and remaining two group for the trial drug. Churna and ointment were used for both excision and incision groups. Albino rats were wounded under aseptic conditions using wound techniques suggested by Marton and Malone [1972] and also by hunts model[1969]. In case of excision wound area of wound was measured once in 4 days by using graph sheet. In case of incision wound tensile strength was found out by using tensinometer on 10th post wounding day. RESULT: The statistical values of both groups were compared with control group and it showed that: 1. Kanchanara ointment promoted epithelization, wound contraction and period of epithelization was reduced in case of excision wound. 2. In incision wound also Kanchanara ointment helps in increasing collagenation and tensile strength. Both ointment and churna group are highly significant when compared with control group. On comparison of ointment group with churna group it statistically showed insignificance. No untoward side effects were noticed during the trial and the wound, healed with minimal scar. CONCLUSION: Kanchanara ointment and its churna is an effective, safe and well tolerated therapy in the treatment of both excision and incision wound.
