Edible Uses
Edible Parts: Fruit Seed Stem
Edible Uses:
Fruit[2]. Soft and pulpy, it is about the size of a small orange[2]. It is highly esteemed in China as a cooling tonic food[183]. Seed - fresh or dried[183, 200]. The seed is about the size of a pea, each fruit containing from 8 to 15 seeds[2]. The seed is usually roasted and then eaten[218]. It is also used as a source of starch[183]. A nutritional analysis is available[218]. Very young stalks and rhizomes[2, 183]. Rich in starch[2].

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].

An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

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.

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.
