Known in Japan as sansho, Japanese pepper has for centuries been as much a condiment as a remedy of Far Eastern pharmacopeia. Its pungent berries, cousins of Sichuan pepper, were traditionally chewed or infused to soothe digestive troubles after heavy meals. Ancient Chinese and Japanese herbalists also recognized warming virtues in it, useful in cold weather.
The dried fruits were traditionally used to promote digestion and relieve feelings of heaviness or bloating after meals.
In traditional Chinese medicine, this pungent spice was used to warm the body and stimulate circulation during cold periods.
The crushed berries or their decoction were used externally, as rubs or compresses, to soothe certain muscle and joint pain.
Chewing a few fruits was an old folk practice to slightly numb the mouth and temporarily calm dental pain.
