Since the establishment of Dietary Supplement Health and Education Act as amendments to the Federal Food, Drug and Cosmetic Act, on October, 1994, herbs, vitamins, minerals and amino acids have been widely applied for dietary supplements. Under the situation, I introduced Aloe from chemical and pharmacological stand point(1993) and Aloe vera gel for an alternative medicine(1996) in Annual report of Faculty of Pharmacy and Pharmaceutical Sciences, Fukuyama University. Present communication deals with efficacy of Aloe extract based on medicinal experiments.

Daio-kanzo-to is a Kampo medicine for acute and chronic constipation which consists of a combination of rhubarb and glycyrrhiza. The contribution of rhubarb is to provide a purgative effect, due to the presence of sennosides. Sennoside A is known to decompose on heating during decoction. Therefore, it is said that Kampo decoctions containing rhubarb rather do not have to be boiled for a long time when targeting the purgative activity of sennoside A. This study was performed to clarify the relationship between decocting times of rhubarb and purgative activity. The variation of sennoside A content in rhubarb during the decocting times of 5 to 240 min was shown to be almost the same as that of Daio-kanzo-to. Compared to sennoside A content between powder and cut rhubarb during the period of decoction, the time when the maximum dissolution was reached had significant differences (powder: 10 min, cut: 40 min). Each purgative activity of powder and cut rhubarb decoctions was in proportion to sennoside A content. Kampo decoctions are generally prepared with cut crude drugs. Therefore, we concluded that usual decoction (40 min) is most suitable for Kampo medicines containing rhubarb to use for constipation.
