Known Hazards

Species in this genus contain hydroxyanthracene derivatives which have a stimulant laxative effect upon the body, and many species are used traditionally as laxatives. In small doses, and for short periods, these can be safe and effective, but used over long periods they can weaken the body's natural ability to defecate and can have a range of long-lasting negative effects upon the body, including anaemia, malabsorption, haematuria and weight loss. Large single doses can cause severe purging.

Other Uses

We have no specific information for this species, but all the members of this genus contain a mixture of compounds (mainly rhamnetin, quercitin and rhamnazin) that make a range of good quality dyes. The colour and its intensity depend upon what part of the plant is used as dyeing material (leaves, fruits and bark are most commonly used), at what period of growth it is collected and in what state it is used. With the use of the corresponding mordants (alum, copper and iron vitriols, tin dioxide, chromium, etc.) it is possible to obtain virtually the entire spectrum of colours from lemon-yellow to purple and dark cinnamon-brown, from olive-green to intensive blue and violet[
