“Ryukakusan 90g” is a herbal medicine (Kikyo, Senega, Apricot Kernel, Licorice) that activates antitussive and expectorant action. Drinking “Ryukakusan” when the throat is inflamed and aching or entangled with sputum spreads the mucous membrane of the throat, increases the secretion of mucus from the inner surface of the trachea, and facilitates the excretion of tongue. Saponin glycoside, the active ingredient of Platycodon grandiflorum, acts directly on the throat to cut tongue and calm the seki.
As it is a fine powder powder, you can drink it without water. It is a home remedy that can be used by families at any time, from children to the elderly.
