Senna bicapsularis is a species of the legumegenusSenna, native to northern South America, from Panama south to Venezuela and Colombia, and also the West Indies.[1] Common names include rambling senna (formerly "cassia"), winter cassia, Christmas bush, money bush, and yellow candlewood.[2] In Florida, Senna pendula is usually cultivated as, and misapplied to, S. bicapsularis.[3][4]
Description
It is a semi-evergreenshrub growing to 3.5 m tall with a low spreading crown that reproduces by seed. It can grow from 2 - 12 metres tall and it branches from near the base.
The leaves are 2.5–9 cm long, pinnate, with six to eight leaflets; the leaflets are 1.6–4.5 cm long and 1.1–2.3 cm broad. The yellow flowers are produced in masses with a few together on short racemes and 12–16 mm long. The plant flowers from autumn to winter, attracting bees and butterflies.[2][5]
Senna bicapsularis is distinguished from Senna pendula by having 3 pairs of leaflets on each leaf and elongated pedicels (flower stalks), while 'S. pendula' has 4-7 pairs of leaflets on each leaf and a gland between each pair of leaflets, with shorter flower stalks. S. bicapsularis flowers from late fall to winter depending on climate, whilst 'S. pendula' can flower from as early as late summer. Senna pendula can grow very easily from seed, while bicapsularis has a tough seed coat that needs mechanical scarification to sprout with success.[6]
Uses
The Nahuas of San Luis Potosi resort to this plant for the healing of the enchantment. For this reason, the patient is cleaned with seven leaves of its leaves, passing them throughout the body. Likewise, as part of this treatment, while the healer prays, he perfumes the patient's body with a charcoal, rosemary and copal incense and then cleanses it with an egg to remove the "bad air" that has taken possession of his body.
The leaves are edible and are used to cure erysipelas in Morelos, and as an antiseptic in Oaxaca. The sap from emaciated leaves can be used externally, with salt, to heal rashes, sores, bites, stings, eczema, scabies, ringworm and thrush. In the 20th century, Maximino Martínez points out the following uses: cathartic and to counteract the effects of arthropod stings.
The seedpod flavour resembles tamarind. The leaves can be cooked as a vegetable, which can be mixed with other leaves, beans or peas.
The leaves and stems contain chaksinelike alkaloids. The seeds contain galactomannan. The presence in the plant of cassin , 2,6-dialkyl-3-hydroxypyridine and socassidine has also been reported
