Few people outside Japan are familiar with this spice, although it has been used in its native country for centuries. Sansho is appreciated not only for its unusual taste and characteristic tingling sensation, but also for its rich set of natural compounds that positively affect the body.

The main active substances are considered to be sansols — alkamides, which are responsible for the very effect of mild numbness. They affect nerve endings, which not only creates a unique sensation when eating, but can also affect bowel function and pain perception. In addition to sunshine, the spice contains a lot of essential oils, antioxidants and vitamin E, which help reduce the level of oxidative stress.

Do not forget about traditional medicine. In the Japanese campo system, sansho was used to improve circulation and relieve stomach problems. Today, data confirm that its compounds are able to reduce the activity of inflammatory molecules and protect tissues from damage.

Interestingly, sansho also affects the intestinal microflora. In fermented foods, it helps the growth of beneficial bacteria, while at the same time inhibiting the development of harmful microbes and fungi. This double effect makes the spice especially valuable for the health of the digestive system.

There are other courses of action. Experience with animals shows that the components of sancho help to lower cholesterol, support liver function and improve metabolism. Antioxidant properties additionally protect blood vessels and the heart from overload.

In cooking, sansho is widely used — from sauces and soups to marinades. It is added to noodles, miso soups, fish marinades and grilled meat. Spice occupies a special place in eel dishes and in a mixture of “shihimi togarashi”, a popular Japanese seasoning of seven spices.

As for safety, the spice is well tolerated in reasonable doses. However, excessive consumption may cause unpleasant sensations in people with sensitive stomachs. Those who are allergic to citrus fruits or peppers should also be careful.
