Safety & Hazards

Millettia and related species in general contain a range of toxic substances, especially isoflavones. Rotenone is probably the best known of these isoflavones and it is found especially in the seeds and roots of the plants. Rotenone is often used locally as a fish poison - the rotenone kills or stuns the fish making them easy to catch, but the fish remain perfectly safe for warm-blooded creatures to eat. 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 also to 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. Millettia species often also contain other potentially toxic compounds, especially saponins and alkaloids[1].

Cultivation Details

HabitDeciduous Climber
Growth—

A plant of the warm temperate to tropical zones, it tolerates temperatures down to between -5 and -10°c and down to about -15°c when given the protection of a warm sunny wall[2]. Succeeds in full sun in a fertile moisture-retentive but well-drained soil[2]. 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[3].

Propagation

Pre-soak the seed for 12 hours in warm water and sow in a greenhouse in spring. 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. Layering in spring. Cuttings of half-ripe wood with the leaves removed, mid summer in moist sand in a frame[2].
