Dr. Zhao Lizhen of China has demonstrated an effective way of using Chinese medicines to treat contractual and hypertrophic scars. ^[7]. The treatment consists of two procedures: Blistering the scar tissues to cause superficial wounds, and, Treating the wound with herbal drugs to heal without scarring. The procedures need to be repeated in cycles in order to totally remove the scar tissues. Despite the time consumption which in some cases had been over a year, published treatment pictures actually showed new skins over-took surface areas previously occupied by scar tissues. It is also reported that patients usually can have their contractual scar tension released in couple treatments. ^[8]. So far, no research paper has been published by Dr. Zhao except for one retrospective clinic report published in Chinese. Two US patents and one Chinese patents have been filed under Lizhen Zhao's name. Chaosmaster (talk) 04:09, 7 May 2008 (UTC)
