Ryukakusan company was established in 1928 under their co., ltd name. In addition to selling its main commodity, “Ryukakusan powder,” it exported technology to Asian countries and carried out various businesses. After that, they carried out unique research on throat medicine and successively developed a variety of tablets, powders, buccal tablets, and other products in the name of Ryukakusan powder. After 1970, the sales of its primary product, Ryukakusan powder, reached a bottleneck. In the late 1990s, it was heavily indebted and fell into an unprecedented business crisis. The company succeeded in developing these new products. Pharmaceutical-assisted jelly products have recently become popular and achieved good results. The company’s medical department entered the generic drug manufacturing industry in 1990.
