Safety & Hazards

Mucuna species often possess irritant hairs on the seedpods and sometimes on the flowers and other parts. These hairs consist of 1-2 small basal cells and a large needle-like top cell. The top cell breaks off easily, piercing the skin and injecting chemical compounds that are present in the hairs. The proteolytic enzyme 'Mucunain' is said to be the active agent[1]. The hairs can contaminate clothes or other objects, and remain active when dried, though they can be destroyed by heat[2, 3, 4]. Intense itching, with reddening of the skin and small papules or urticaria occur a few minutes after contact with the hairy parts of the plant. There is no serious danger, unless the hairs get into the eye, in which case, in extreme situations, they have caused blindness. To remove the hairs from the skin, adhesive tape and washing with water and soap are considered useful. Dermatitis can be treated with corticosteroid ointment. See a doctor immediately if hairs go into the eyes[3].

Cultivation Details

HabitPerennial Climber
Growth—

Prefers a well-drained, moist, humus-rich soil and a position in full sun or partial shade[5]. This species is extremely similar to Mucuna pruriens, and is only distinguished by the thickly textured robust-veined ovate-rhombic leaflets with indumentum abaxially conspicuously sparser on the veins than on the leaf surface, the lower part of the inflorescence with many flowerless nodes with scars or persistent bracts, and the almost straight legume[6].
