Kampo (Japanese herbal medicine)

Shoseiryuto (Kampo for runny nose, allergy)

Shoseiryuto (Kampo extract)

Shoseiryuto is the Kampo answer to watery runny nose, sneezing and hay fever, and is popular during Japan's cedar pollen season for people who want to avoid drowsy antihistamines. It contains ephedra, so it can cause palpitations or insomnia in sensitive people.
