Did you know that the hairy pods of Velvet Bean produce an extreme skin itching after contact? 

Velvet Bean (Mucuna pruriens). Flowers and fruits.

Velvet Bean - Mucuna pruriens

Mucuna pruriens is a tropical legume native to Africa and tropical Asia and widely naturalized and cultivated. Its English common names include velvet bean, Bengal velvet bean, Florida velvet bean, Mauritius velvet bean, Yokohama velvet bean, cowage, cowitch, lacuna bean, and Lyon bean. The plant is notorious for the extreme itchiness it produces on contact, particularly with the young foliage and the seed pods. It has value in agricultural and horticultural use and has a range of medicinal properties.

The plant a tropical legume. It is an annual climbing shrub with long slender vines that can reach over 15 m (49 ft) 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, ranging in size from 20-25 cm in length and 7.5-12.5 cm in width. The sides of the leaves are often heavily grooved and the tips are pointy. In young M. 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 (0.20 in) long.

Its flowers are white, lavender to dark purple and hang in long clusters. The flower heads take the form of axially arrayed panicles. They are 15–32 cm (5.9–12.6 in) long and have two or three, or many flowers. The accompanying leaves are about 12.5 mm (0.49 in) long, the flower stand axes are from 2.5–5 mm.

The plant also produces clusters of pods. The seed pods are about 10 cm long, containing seeds known as Mucuna beans. The flowers, seedpods, and seeds are covered with reddish-orange hairs. There are two forms of the hairs. The non-stinging hairs are silky, while the stinging hairs, called Mucunain, produce an extremely itchy sensation when coming in contact with them. The itch is caused by a protein known as mucunain. The species name "pruriens" (from the Latin, "itching sensation") refers to the results to be had from contact with the seed pod hairs. The seeds are flat and black, and when matured, they have a glossy look to them. The dry weight of the seeds is 55–85 g (1.9–3.0 oz)/100 seeds.

The hairs lining the seed pods contain serotonin and the protein mucunain which cause severe itching when the pods are touched. The calyx below the flowers is also a source of itchy spicules and the stinging hairs on the outside of the seed pods are used in itching powder. Scratching the exposed area can spread the itching to other areas touched. Once this happens, the subject tends to scratch vigorously and uncontrollably and for this reason the local populace in northern Mozambique refer to the beans as "mad beans" (feijoes malucos). The seed pods are known as "Devil Beans" in Nigeria.

In Central America, velvet beans have been roasted and ground to make a coffee substitute for decades; its goes by the common name of "nescafé" in these regions, as well as in Brazil, for this reason. It is still grown as a food crop by the Ketchi indigenous people in Guatemala; the bean is cooked as a vegetable. 

In Indonesia, particularly Java the beans are eaten and widely known as 'Benguk'. The beans can also be fermented to form a food similar to tempe and known as Benguk tempe or 'tempe Benguk'.

In Brazil the seed has been used internally for Parkinson's disease, edema, impotence, intestinal gas, and worms. It is considered a diuretic, nerve tonic, and aphrodisiac. Externally it is applied to ulcers. Velvet bean has a long history of use in Indian Ayurvedic medicine, where it is used for worms, dysentery, diarrhea, snakebite, sexual debility, cough, tuberculosis, impotence, rheumatic disorders, muscular pain, sterility, gout, menstrual disorders, diabetes, and cancer. In India it is considered an aphrodisiac, menstrual promoter, uterine stimulant, nerve tonic, diuretic, and blood purifier.

In many parts of the world Mucuna pruriens is used as an important forage, fallow and green manure crop. Since the plant is a legume, it fixes nitrogen and fertilizes soil.
