前些年我发表了紫云膏对胼胝和鸡眼有特效的文章。从那时起我收到了日本全国许多患者来信表示感谢(用紫云膏治疗了肼胝和鸡眼)。但也有治不好的。其中四国地方某旅馆一位老年妇女来信说,用了半年紫云膏但没有一点疗效。我觉得很奇怪。 A few years ago I posted an article on the effects of Ziyun paste on callus and corns. Since then I have received letters from many patients in Japan throughout the country (hydrazine and corns treated with purpura). But there are also bad governance. In a letter from an elderly woman in a hotel in the four countries, it took half a year to cure but without any effect. I feel strange.
