Material uses
A yellow dye is obtained from the twigs[6]. black dye can be obtained when the twigs are mixed with pine gum[10]. A red-brown dye can be made from the bark and leaves[10]. A pink-tan dye can be made from the fruit[10]. The ashes of the plant can be used as a mordant to fix dyes[10]. An oil is extracted from the seeds[11]. It attains a tallow-like consistency on standing and is used to make candles. These burn brilliantly, though they emit a pungent smoke[11]. The roots have been used as a perfume and deodorant[10]. The buds have been used on the body as a medicinal deodorant and perfume[10]. The leaves have been rubbed on the body as an insect and snake repellent[10]. Some caution should be employed here, see the notes above on toxicity[K].
The branches are tough and slender, they are stripped of their bark and split into several strands then used in basket making[12][3][4][5][6][10].Medicinal uses(Warning!)
The fruit is analgesic, astringent and stomachic[10]. It has been eaten as a treatment for stomach problems and grippe[10]. The dried berries have been ground into a powder and dusted onto smallpox pustules[10]. The fruit has been chewed as a treatment for toothache and also used as a mouthwash[10]. A decoction of the fruit has been used as a wash to prevent the hair falling out[10]. The leaves are astringent, diuretic, emetic and haemostatic[10]. An infusion of the leaves has been used in the treatment of head colds[10]. A decoction of the leaves has been drunk to induce impotency as a method of contraception[10]. A poultice of leaves has been used to treat itches[10]. An infusion of the bark has been used as a douche after childbirth[10]. The bark has been chewed, and the juice swallowed, as a treatment for colds and sore gums[10]. A decoction of the root bark has been taken to facilitate easy delivery of the placenta[10].
The roots have been used as a deodorant[10]. The buds have been used on the body as a medicinal deodorant and perfume[10].Ecology

Cultivation
The young growth in spring can be damaged by late frosts. This species is closely allied to R. aromatica[14]. Plants have brittle branches and these can be broken off in strong winds[8]. Plants are also susceptible to coral spot fungus[14]. Plants in this genus are notably resistant to honey fungus[8]. Many of the species in this genus are highly toxic and can also cause severe irritation to the skin of some people, whilst other species such as this one are not poisonous. It is relatively simple to distinguish which is which, the poisonous species have axillary panicles and smooth fruits whilst non-poisonous species have compound terminal panicles and fruits covered with acid crimson hairs[15][11]. The toxic species are sometimes separated into their own genus, Toxicodendron, by some botanists[8].
Dioecious. Male and female plants must be grown if seed is required.Crops
