Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Edible Uses: Oil  Oil

Fruit[183]. The young fruits are pickled[177]. The pulp of older fruits is eaten[179]. Mature fruits are about 10cm long[200]. Leaves and young shoots - cooked and used as a vegetable[177, 183]. An edible starch is obtained from the root[183]. It requires leeching[179], which probably means that it has a bitter flavour[K]. The root is harvested in the autumn, cut into thick slices, soaked for 4 - 5 days in water, changing the water daily until the root disintegrates and can be mashed into a fine pulp. It is then steamed into cakes or used for making dumplings[177, 178, 179]. An edible oil is obtained from the seed.

The root is taken internally in the treatment of diabetes, dry coughs, and to assist in the second stage of labour[176, 238]. The root is harvested in the autumn and dried for later use[238].

One website user has noted that Trichosanthes kirilowii is an 'important Chinese medicinal plant of which the whole fruit, seeds, rind, AND tuberous-rhizome are all used regularly in medicine. While certain types of extracts may be toxic and the raw/unprocessed root may be toxic, to state unequivocally that the root is toxic is to err.'

Special Uses

Cultivation details

Requires a rich well-drained soil and plenty of moisture in the growing season[1, 200]. Sometimes cultivated in China for its edible fruit and medicinal uses. Male plants are favoured for root production[238]. This species is not winter hardy in Britain and usually requires greenhouse cultivation[238]. However, it may be possible to grow it as an annual in a very warm sheltered bed outdoors[1]. A climbing plant, supporting itself by means of tendrils[238]. Dioecious, male and female plants must be grown if seed is required[238].
