Essential for health
Throat barrier function "ciliary movement"
The throat has a barrier function called "ciliary movement" that expels foreign substances such as dust, bacteria, chemical substances, and pollen that enter the body with breathing.
Thanks to this function, we can live healthily.
However, when the "ciliary movement" weakens due to cold or dry air, foreign substances cannot be expelled. Normally, foreign substances are expelled by "coughing" or "phlegm," but these "coughs" and "phlegm" worsen and cause inflammation in the throat.
Inflammation further weakens the "ciliary movement," creating a vicious cycle that not only causes poor health but also prolongs the condition.
For times like these
Coughing, phlegm, hoarseness, scratchy throat, sore throat
How to take
Ryukakusan is a medicine whose herbal ingredients act directly on the throat mucosa and activate the ciliary movement of the throat.
If taken with water, the ingredients that act on the throat mucosa will be washed away, so please be sure to take it without water. Also, refrain from eating or drinking for 15 to 30 minutes after taking it.
