Haiyasumin A is a medicine effective for alleviating temporary insomnia symptoms such as difficulty falling asleep and light sleep. The active ingredient of Haiyasumin A, diphenhydramine hydrochloride, has generally been used to relieve allergy symptoms such as skin itching, sneezing, and runny nose, but it also has the effect of causing drowsiness when taken. Haiyasumin A was developed focusing on this drowsiness-inducing effect.
