Edible Uses
Edible Parts: Leaves.
Edible Uses: Condiment.

Seed - cooked. It is ground into a powder and used as a condiment, a pepper substitute[1, 2, 11, 34, 183]. The fruit can also be used[116]. It is often heated in order to bring out its full flavour and can be mixed with salt for use as a table condiment[183]. The ground and dry-roasted fruit is an ingredient of the Chinese 'five spice powder'[238]. The bark and leaves are used as a spice[2, 105, 238]. Young leaves - raw or cooked. They are used in soups or as a flavouring in salads[177, 179, 183].

Antibacterial;  Antifungal;  Antiperiodic;  Antitussive;  Carminative;  Diuretic;  Parasiticide;  Stimulant;  
Stomachic.

Antiperiodic, antitussive, carminative, diuretic, parasiticide, stimulant[178]. The fruit contains a essential oil, flavonoids and isoquinoline alkaloids[279]. It is anthelmintic, antibacterial, antifungal and stomachic[279]. It inhibits the synthesis of prostaglandin and, in larger doses, is toxic to the central nervous system[279]. It is used in Korea in the treatment of tuberculosis, dyspepsis and internal parasites[279]. The resin contained in the bark, and especially in that of the roots, is powerfully stimulant and tonic[82].
Other Uses
Parasiticide.

None known
Cultivation details
Easily grown in loamy soils in most positions, but prefers a good deep well-drained moisture retentive soil in full sun or semi-shade[1, 11, 200]. A very ornamental plant[1], it is hardy to about -15°c[184]. Flowers are formed on the old wood[206]. The bruised leaves are amongst the most powerfully aromatic of all leaves[245]. Dioecious. Male and female plants must be grown if seed is required. Self-sown seedlings have occasionally been observed growing in bare soil under the parent plant[K].
Propagation
Seed - best sown in a greenhouse as soon as it is ripe in the autumn. Stored seed may requires up to 3 months cold stratification, though scarification may also help[113]. Sow stored seed in a cold frame as early in the year as possible. Germination should take place in late spring, though it might take another 12 months. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in a cold frame for their first winter. Plant them out in early summer. Cuttings of half-ripe wood, July/August in a frame. Root cuttings, 3cm long, planted horizontally in pots in a greenhouse. Good percentage[78]. Suckers, removed in late winter and planted into their permanent positions[113].

I've found in french literature (cf biblio at the end) the following info : - the powdered dried fruit is named shichimi in Japan and used on food. - Young leaves are used in soups, accompany the miso paste (japanese paste of soja beans) - The flower buds are kept in the soja sauce and rice wine.

Bibliog : - Lesley Bremnes, Les plantes aromatiques et médicinales, Bordas Nature, 1996 - B. Boullard, Les plantes médicinales du monde, Ed. Estem, 2001

Any other details about the plant is welcome! Thank you for the incredible site! Thomas

This plant and its seed and spice" sansho" has been prohibited by FDA. I would like to know the reason. FDA might concern some chemical component. Note that sansho is an imporrtant spice for some Japanese dish.

what about xantossilin, an isomer of cantatidin? I read that is found in Japanese pepper. Are there any chemical relationship with the cantaridin produced by the spanish fly (Lytta vescicatoria?)

As far as I understand, the ban on sansho has been lifted if the material is heated to at least 70 degrees C before shipment. The ban was originally put in place to prevent the spread of citrus canker, a devastating bacterial disease of citrus. Zanthoxylum is also a host of this disease. This genus is in the same family as Citrus.

The FDA has banned "sansho" because they haven't carried out tests on it. Therefore it is suspect. But there is abso;utely no reason for their suspicion other than they are suspicious of everything that is not native to the USA. Which includes about 300,000,000 people? The last comment was mine, but the rest is from FDA source...?

You can get it mail order in the US as a plant though "One Green World" (www.onegreenworld.com) it is under the Ornamentals and More section. Have fun. Kelly

Be careful! I chewed some raw seeds of Zanthoxylum piperitum, some of the seed lodged in my throat and it went into a spasm of swallowing to remove it - I could not breathe properly for 5 mins as I was swallowing so hard and fast. Eventually recovered, but only after being on my hands and knees for ten minutes.

My zanthoxylum piperitums have been steadily growing from the cute little spindles they were in spring of 2011 when I received them. One of mine was attacked by spider mites and I sprayed it with a pesticide to kill them. Both plants leafed out as expected and are busy growing new branches/root complexes. I am hopeful they will bloom either next spring or the spring of 2014. I currently use the spring leaves (not too much), called kinome in Japan, as a gift to a friend who runs a sushi bar and is from Japan. He says kinome is very hard to find here.

Actually this plant IS self-fertile. On every plant there are BOTH male and female flowers, although every flower is either male or female.
