Description

 

The plant is an annual, climbing shrub with long vines that can reach over 15 m in length. When the plant is young, it is almost completely covered with fuzzy hairs, but when older, it is almost completely free of hairs. The leaves are tripinnate, ovate, reverse ovate, rhombus shaped or widely ovate. The sides of the leaves are often heavily grooved and the tips are pointy. In young Mucuna pruriens plants, both sides of the leaves have hairs. The stems of the leaflets are two to three millimeters long. Additional adjacent leaves are present and are about 5 mm long.

The flower heads take the form of axially arrayed panicles. They are 15 to 32 cm long and have two to three, or many flowers. The accompanying leaves are about 12.5 mm long, the flower stand axes are from 2.5 to 5 mm. The bell is 7.5 to 9 mm long and silky. The sepals are longer or of the same length as the shuttles. The crown is purplish or white. The flag is 1.5 mm long. The wings are 2.5 to 3.8 cm long.

In the fruit ripening stage, a 4 to 13 cm long, 1 to 2 cm wide, unwinged leguminous fruit develops. There is a ridge along the length of the fruit. The husk is very hairy and carries up to seven seeds. The seeds are flattened uniform ellipsoid, 1 to 1.9 cm long, 0.8 to 1.3 cm wide and 4 to 6.5 cm thick. The hilum, the base of the funiculus (connection between placenta and plant seeds) is a surrounded by a significant arillus (fleshy seeds shell).

Mucuna pruriens bears white, lavender, or purple flowers. Its seed pods are about 10 cm long[1] and are covered in loose orange hairs that cause a severe itch if they come in contact with skin. The chemical compounds responsible for the itch are a protein, mucunain,[1] and serotonin. The seeds are shiny black or brown drift seeds. It is found in tropical AfricaIndia and the Caribbean.

The dry weight of the seeds is 55 to 85 g/100 seeds.[5]

The number of chromosomes in the plant cells is 2n = 20, 22 or 24.[clarification needed]

In many parts of the world Mucuna pruriens is used as an important foragefallow and green manure crop.[6] Since the plant is in the legume family (peas and beans), it, with the help of nitrogen fixing bacteria, takes nitrogen gas from the air and combines it with other chemical compounds producing fertilizer and improving the soil.

Mucuna pruriens is a widespread fodder plant in the tropics. To that end, the whole plant is fed to animals as silage, dried hay or dried seeds. Mucuna pruriens silage contains 11-23% crude protein, 35-40% crude fiber, and the dried beans 20-35% crude protein.

Mucuna pruriens is sometimes used as a coffee substitute called “Nescafe” (not to be confused with the commercial brand Nescafé). Cooked fresh shoots or beans can also be eaten. This requires that they be soaked from at least 30 minutes to 48 hours in advance of cooking, or the water changed up to several times during cooking, since otherwise the plant can be toxic to humans. The above described process leaches out chemical compounds such as levodopa, making the product suitable for consumption. If consumed in large quantities as food, unprocessed Mucuna pruriens is toxic to nonruminant mammals including humans.

USE

In history, M. pruriens has been used as an effective aphrodisiac.[7][8]

It is still used to increase libido in both men and women due to its dopamine inducing properties. Dopamine has a profound influence on sexual function.[1][9][10]

Mucuna pruriens seeds have also been found to have antidepressant properties in cases of depressive neurosis when consumed.[11]

Dried leaves of Mucuna pruriens are sometimes smoked.[1]

Mucuna pruriens has also recently become popular among lucid dreaming enthusiasts: when combined with other supplements that stimulate the cholinergic system, the dopamine presumably produced from the consumption of Mucuna pruriens confers upon the lucid dreamer greater motivation and confidence.[citation needed]

The hairs lining the seed pods contain 5-hydroxytryptamine (serotonin) which causes severe itching (pruritus).[12][13] The hairs on the outside of the pods of Mucuna pruriens are a common ingredient initching powder.[14] Use of Mucuna pruriens is documented in Siddha medicine for a number of uses, including improving sexual function[15] Mucuna pruriens is used in the countries of Benin andVietnam as a biological control for problematic Imperata cylindrica grass.[6] Mucuna pruriens is said to not be invasive outside its cultivated area.[6]
