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.

Antiperiodic;  Emetic;  Expectorant;  Febrifuge;  Purgative.

This plant is commonly used in Chinese herbalism, where it is considered to be one of the 50 fundamental herbs[218]. The leaves are purgative[218]. They are used in the treatment of stomach cancer[218]. The juice of the leaves is used in Nepal to treat coughs, colds and bronchitis[272]. A decoction of the stem bark is used in the treatment of fevers[218]. a decoction of the leaves is used to treat malarial fever[272]. The root contains several alkaloids[283] and is emetic, expectorant, febrifuge and purgative[51, 61, 146, 147, 176, 218, 240, 272]. The juice of the root is used in Nepal to treat fevers and indigestion[272]. This plant is 26 times more powerful than quinine in the treatment of malaria but causes vomiting[176]. Substances in the plant are 100 times more powerful than quinine, but they are poisonous[218].
Other Uses
The wood is used as a fuel[272].
Cultivation details
Landscape Uses:Erosion control, Ground cover, Massing, Rock garden. An easily grown plant, succeeding in an open loamy soil[1]. The flowers vary in colour according to the type of soil they grow in, the best blue colour is formed when plants are in very acid soils[260]. One report says that this plant is probably not hardy outdoors in Britain[11] whilst another says that some provenances tolerate temperatures down to about -5°c[260] and another report says that the forms in cultivation are only fully hardy in southern Cornwall[1]. This same report goes on to say that those forms probably do not belong to D. febrifuga in the strict sense[1]. This plant is cultivated in Russia as an anti-malarial herb[240]. Special Features:Not North American native, Attractive flowers or blooms.
Propagation
Seed - we have no information on this species but suggest sowing the seed in a greenhouse in spring and only just covering it. Do not allow the compost to dry out. When 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. Cuttings. No details are given, we suggest trying in August with almost ripe wood in a frame.

I HAVE BEEN GROWING THIS PLANT OUTSIDE IN A SHELTERED ACID WOODLAND CLOSE TO THE SEA IN ABBOTSBURY GARDENS IN DORSET, UK, FOR 15 YEARS NOW. In the coldest winters it looses its leaves but comes back in spring -3 is our average winter cold .occasionally -6 We take cuttings which root quite easily for insurance plants.It has a vivid blue flower that often gets confused with nearbt Hydrangeas

I have a shrub that I think may be a dichroa. Mine started flowering in September and is now at its peak. It matches the photos I've seen but there seems to be conflicting information about flowering times. If anyone could help with identification, I could send a photo. January 7th
