Safety & Hazards

The plant contains rotenone and has been used traditionally as a fish poison - the rotenone kills or stuns the fish making them easy to catch, but the fish remain perfectly edible for mammals. Rotenone is classified by the World Health Organization as moderately hazardous. It is mildly toxic to humans and other mammals, but extremely toxic to many insects (hence its use as an insecticide) and aquatic life, including fish. This higher toxicity in fish and insects is because the lipophilic rotenone is easily taken up through the gills or trachea, but not as easily through the skin or the gastrointestinal tract. The lowest lethal dose for a child is 143 mg/kg, but human deaths from rotenone poisoning are rare because its irritating action causes vomiting. Deliberate ingestion of rotenone, however, can be fatal. The compound decomposes when exposed to sunlight and usually has an activity of six days in the environment.

Cultivation Details

HabitDeciduous Tree
Growth—

A plant of the lowland tropics, found at elevations up to 750 metres[1]. It is found in areas where the mean annual rainfall is within the range 700 - 3.000mm and the temperatures range from 18 - 29°c[1]. It grows best in areas with a well-distributed rainfall pattern[2]. Succeeds in shallow and infertile soils[1]. All species in this genus tolerate a wide range of soil conditions, from fertile loams to barren areas, though a well-drained soil is preferrable[2]. Although it is chemically well investigated, no medicinal, insecticidal or piscicidal uses are known[3]. 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[2].
