Introduction and description
Abuta is a genus in the flowering plant family Menispermaceae, of about 32 species, native to tropical Central and South America and usually found in the tropical rain forest.
The genera Anelasma Miers and Batschia Thunb. have been brought into synonymy with Abuta. Abuta is usually classified in the tribe Anomospermeae Miers, together with Anomospermum Miers.
The Abuta genus is a family of dioecious climbers or rarely erect trees or shrubs (Abuta concolor) with simple leaves. Flowers are in composed panicles. Male flowers: sepals 6, in 2 whorls, petals absent, stamens 6, connate or free, introrse, anthers with a longitudinal or transverse dehiscence. Female flowers: sepals and petals as in male, staminodes 6, carpels 3, drupes ovoid, endocarp woody, condyle septiform, endosperm ruminate, embryo curved, cotyledons appressed.
Abuta is one of the components of the arrow poison curare of some indigenous tribes of South America (especially Abuta imene from Colombia), as such one can see that this family of plants needs to be treated with some respect.
The roots of Abuta rufescens are used as a medicine in diseases of the urogenital tract, but according to Wikipedia “it is dangerous.” In contrast Abuta grandiflora has been used medicinally for some time and extracts are sold, principally of the bark. In effect you have to know which specific plant to use.
Where scientific research interest is currently centred, however, is in the anti-parasitic and anti-malarial activity of the plants.
The dichloromethane extracts of Abuta grandifolia and Minthostachys setosa (Labiatae) demonstrated high larvicidal activity against Aedes aegypti, the most active being the dichloromethane extract of A. grandifolia.
