Herbal medicine

Several Erythrina tree species are used by indigenous peoples in the Amazon as medicines, insecticides and fish poisons. Tinctures and decoctions made from the leaves or barks of Mulungu are often used in Brazilian traditional medicine as a sedative, to calm an overexcited nervous system, to lower blood pressure and for insomnia and depression.
Commercial preparations of Mulungu are available in Brazilian drugstores, but is not very widely known in North America and almost unknown in Europe; mostly appearing as an ingredient in only a few herbal formulas for anxiety or depression.
This tree reaches up to 15 meters in height.

Mulungu extract composition

Chemical compounds found in Mulungu extract include the tetrahydroisoquinoline alkaloids erythravine and -11α-hydroxy-erythravine.

Seeds

Its red-orange seeds are considered very toxic. Ingestion should be avoided and there is a danger of death.
The seeds germinate in organo-sandy substrates covered with a layer between 0.5 - 2 cm of the same, being irrigated daily, emerging between 7 and 16 days having high germination rate. Breaking dormancy is not usually necessary. But when it is needed, it is performed through germinative treatments consisting of mechanical scarification of the area opposite to the hilum and immersion in water for 24 hours.
