Botanical Name : Zanthoxylum bungeanum
Species: Zanthoxylum bungeanum
Common Names: Szechuan Peppercorn
Habitat:Zanthoxylum bungeanum is native to E. Asia – China. It grows on waysides and thickets to 2000 metres in W. China.
Zanthoxylum bungeanum is a deciduous Shrub growing to 6 m (19ft 8in). The flowers are dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required)The plant is not self-fertile.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist soil.
It is not a true peppercorn, but rather the dried berry/seed of a deciduous prickly ash tree. The 3-4 mm berry has a rough reddish brown shell that is split open and a black seed inside. The black seed is bitter and can be discarded. The red shell can be added whole to stewed dishes or ground to a powder and used a seasoning. The spice has a unique aroma and flavor that is not as pungent as black pepper and has slight lemony overtones.
Szechuan peppercorns are one of the five spices in Chinese five-spice powder. Called sansho in Japan, they are used in the spice mixture shichimi togarashi, or Japanese seven-spice seasoning.
It is said to be often cultivated for its edible fruit, especially in hot dry river valleys in China. There is some doubt over the correct name for this species, it might be no more than a synonym of Z. simulans. The following notes are based on the general needs of the genus. Prefers a good deep well-drained moisture retentive soil in full sun or semi-shade. Dioecious. Male and female plants must be grown if seed is required. Flowers are formed on the old wood.
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. 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. Suckers, removed in late winter and planted into their permanent positions.
Seed – used as a condiment, a pepper substitute. Highly prized. The fruit is rather small but is produced in clusters which makes harvesting easy. Each fruit contains a single seed.
Anaesthetic; Anthelmintic; Aromatic; Astringent; Carminative; Diaphoretic; Diuretic; Emmenagogue; Stimulant; Vasodilator; Vermifuge.
The fruit is anaesthetic, anthelmintic, aromatic, astringent, carminative, diuretic, emmenagogue, stimulant, sudorific, vasodilator and vermifuge. It is pulverised then mixed with water for internal application in the treatment of chills and pains in the abdomen, vomiting, cold-damp diarrhoea and dysentery, ascariasis-caused abdominal pain and moist sores on the skin. The pericarp is anaesthetic, anthelmintic, antibacterial and antifungal. It is effective against the pork tapeworm, Taenia solium, and is also used in the treatment of gastralgia, dyspepsia, diarrhoea, abdominal pain, ascariasis and dermal diseases. The pericarp contains geraniol. This lowers the blood pressure, is mildly diuretic in small doses but in large doses inhibits the excretion of urine, and also increases peristalsis of the abdomen at low doses though inhibits it at large doses
