Scientific name:Staurogyne merguensis Kuntze ・Origin: Malaysia(Malay peninsula, Penang Island, Lang Kawi Island) But in Penang and Lang Kawi, the number of this plant has decreased sharply those days. ・It is growing on a rock surface near a waterfall. If you drink cold water after nibbling this leaf, you will taste sweetness in the water. It is because the leaf contains the glycoside called strogin. ・Effect duration: 20minutes to 30 minutes Strogin is bearable to heat because it is glycoside. Accordingly, if you dry staurogyne, it can be preserved at normal temperatures. ・Nobody can succeed in growing staurogyne. But I have just begun to grow it by using tissue culture technique.(first trying in Japan) ・Strogin is not approved as a additive by the Ministry of Health and Welfare because it is not yet applied. But I think that strogin will be approved as an existing additive, since it is commonly used in a certain part of Malaysia. The taste-modifier plants that I am showing here at this web site are commonly used in an original place. |
