Tourmaline stone roasting method [Nejimebiwacha 24] is a healthy tea produced in Kagoshima prefecture, which was created through joint research between Totsugawa Farm and Kagoshima University. We are jointly applying for a patent because we obtained good health results in animal experiments. Using 100% loquat leaves from Kagoshima prefecture, it is a Kagoshima prefecture special product certified product. The active ingredient was extracted by washing with sun-dried and original tourmaline stone roasting method, Hadomizu (water processed with special equipment). One packet per liter is OK. We recommend 100% screw loquat tea from Kagoshima prefecture.
