Ryukakusan Co., Ltd. (株式会社 龍角散) is a Tokyo-based Japanese pharmaceutical company that develops and markets prescription and over-the-counter drug (OTC) products, especially throat and swallowing products.[1]
History
In the early 18th century, "Ryukakusan" was a powdered Kampo cough medicine produced by the Fuji family, physicians to the Satake Clan of the Akita Domain.[2][3][4] Literally "dragon antler powder", it was named after its ingredients: long gu ("dragon bone"), deer antler powder, and borneol. Shoteiji Fujii began selling it as medicine for the public in 1871. In 1894, his son Tokusaburo revised the formula, introducing the now-familiar herbal formulation in fine powder form.[5]
