Ryukakusan

Ryukakusan, whose characters mean “dragon horn powder,” is a well-known medicine created at the end of the Edo Period, when there were still samurais in Japan. The powder was originally used by the Japanese emperor and made by the physicians of the Fuji family. The tradition of medicine was passed down from father to son until Ryukakusan Co., Ltd. was finally founded in 1871. The company has been handed down through generations of the Satake clan of the Akita Domain, now represented by President Ryuta Fujii. Ryukakusan has obtained patent rights worldwide, including in Asia, the United States, and Europe. Today, we can find the dragon horn powder in several product formulations offered by this time honored company. From easy-melt flavored stick-pack, powders, tablets, and many flavored coated hard lozenges.
