About
Senna alata is an important Neotropical medicinal tree, as well as an ornamental flowering plant in the subfamily Caesalpinioideae. It also known as emperor's candlesticks, candle bush, candelabra bush, Christmas candles, empress candle plant, ringworm shrub, Roman candle, or candletree. A remarkable species of Senna, it was sometimes separated in its own genus, Herpetica.
How to grow it
This species is easy to grow from the seed. They may either be sown directly or started in a nursery.
Uses
Senna alata (also known as Cassia alata) is often called the ringworm bush because of its very effective fungicidal properties, for treating ringworm and other fungal infections of the skin. The leaves are ground in a mortar to obtain a kind of "green cotton wool". This is mixed with the same amount of vegetable oil and rubbed on the affected area two or three times a day. A fresh preparation is made every day. Its active ingredients include the yellow chrysophanic acid.
