Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.
Analgesic  Aphrodisiac  Astringent  Deobstruent  Oxytoxic  Tonic

The leaf is used in cases of difficult parturition[218]. All parts of the plant are considered to be astringent, deobstruent and tonic[218]. The seed is a sweet and sour astringent herb that acts as a tonic for the kidney and the spleen[238]. The seed is analgesic and aphrodisiac[218]. It is taken internally in the treatment of chronic diarrhoea, vaginal discharge, kidney weakness associated with frequent urination, impotence, premature and involuntary ejaculation and nocturnal emissions[238, 279].

Cultivation details

Management: Standard  Regional Crop  Staple Crop: Balanced carb

A water plant, it requires a rich soil, preferably growing in still water[238]. It can be grown in still or slowly flowing water[200]. In cultivation in temperate greenhouses, the plant is often grown as an annual[200]. It requires about 0.75 cubic metres of root run[200]. This species is not very cold hardy. One report says that it succeeds in zone 8[200] which would mean that it tolerates temperatures down to between -5 and -10°c but this must be viewed with some doubt. It is unlikely to succeed outdoors in Britain, at least when grown as a perennial[K]. Frequently cultivated as an edible plant in China and India, the seeds are normally available in Chinatown markets in the West[183].

Carbon Farming

  • Management: Standard  Plants grow to their standard height. Harvest fruit, seeds, or other products. Non-Destructive management systems.
  • Regional Crop  These crops have been domesticated and cultivated regionally but have not been adopted elsewhere and are typically not traded globally, Examples in this broad category include perennial cottons and many nuts and staple fruits.
  • Staple Crop: Balanced carb  (0-15 percent protein, 0-15 percent oil, with at least one over 5 percent). The carbohydrates are from either starch or sugar. Annuals include maize, wheat, rice, and potato. Perennials include chestnuts, carob, perennial fruits, nuts, cereals, pseudocereals, woody pods, and acorns.

Plant Propagation

Seed - best sown as soon as it is ripe, the seed has a short viability and must not be allowed to become dry. Sow the seed in pots in a greenhouse at about 21°c and immerse the pots in water. As soon as they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts.
