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 >>>

Tonic

Bu Gu Zhi is valued in Chinese herbal medicine as a tonic remedy and is used to improve general vitality[254]. Modern research has shown that it is also of value in the treatment of skin disorders, including vitiligo. Some caution should be employed when applying the herb externally, however, since it can sensitise the skin and cause an allergic reaction to sunlight[254]. The one-seeded fruits (or the seed plus the seedpod) are highly regarded as an aphrodisiac and tonic to the genital organs[218]. The seed is anthelmintic, antibacterial, aphrodisiac, astringent, cardiac, cytotoxic, deobstruent, diaphoretic, diuretic, stimulant, stomachic and tonic[4, 147, 176, 178, 218, 240]. It is used in the treatment of febrile diseases, premature ejaculation, impotence, lower back pains, frequent urination, incontinence, bed wetting etc[240, 254]. It is also used externally to treat various skin ailments including leprosy, leucoderma and hair loss[218, 240]. The seed and fruit contain psoralen. This causes the skin to produce new pigment when exposed to sunlight and is used for treating vitiligo and psoriasis[176]. The antibacterial action of the fruit inhibits the growth of Mycobacterium tuberculos[176]. The fruit is gathered when ripe in the autumn and can be dried for later use[254]. The root is used for treating dental caries[218]. The plant yields a useful medicinal oleoresin, it treats kidney disorders, impotence, premature ejaculation, lumbago etc[4, 147, 176, 178].

Cultivation details

We have very little information for this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors at least in the milder parts of the country. The following notes are based on the general needs of the genus. Succeeds in an ordinary garden soil[1]. Requires a well-drained soil in a sunny position[200]. Plants are very intolerant of root disturbance, they are best planted out into their permanent positions whilst still small[200]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[200].

Propagation

Pre-soak the seed for 24 hours in warm water and then sow in early to mid spring in a greenhouse. Either sow the seed in individual pots or pot up the young seedlings as soon as possible in order to avoid root disturbance. Grow them on in the pots until planting out in their final positions. It is usually impossible to transplant this species without fatal damage to the root[200]. Division in spring. With great care since the plant resents root disturbance. It is virtually impossible to divide this species successfully[200].
