Botanical Name :Marsdenia tinctoria R. Br.

Other Scientific Names :Marsdenia akkar Blanco ,Marsdenia tagudina Blanco ,Asclepias tinctoria Roxb. ,Pergularia tinctoria Spreng.
Common Names:  Ariñgit (Bik..),Lamus (Bag.),Payañgit (Tag.),Tayom-tayom (Ilk.),Broad-leafed indigo (Engl.,Lan ye teng (Chin.) , Java indigo (Engl.) ,Tarum (Malaysia)

Habitat :   Payangit is widly distributed from subtropical Himalays of Nepal and India,through Thailand and Peninsular Malayasia,southwards to Indonesia (Sumatra and Java) and the Philippines: east and northwest  to southern China, Taiwan, and the Ryukyu island. It is very rarely caltivated in India,Burma,Thailand and Indonesia(Sumatra & Java).

Payañgit is a twining, half-woody plant with very slender, smooth branches. Leaves are opposite, ovate to broadly ovate or somewhat rounded, 9 to 16 cm long, 5 to 10 cm wide, with pointed tip and heart-shaped base. Flowers are small, fragrant, yellowish green, borne in alternating clusters at the axils of the leaves, and 4 to 7 cm long.

Leaves sometimes used internally for stomach aches and vaguely diagnosed intestinal afflictions.
In the Sikkim Himalayas, leaf juice taken three times daily for stomachaches.

Other Uses:
*Dye: In Burma, green is produced by dipping threads that have been dyed yellow in a boiling decoction of the leaves and twigs of the creeping Marsdenia tinctoria

*Its dye, like true indigo, is regarded as a good black dye for the hair.

Studies

Pregnane Glycosides: Study yielded three new pregnane glycosides, tinctorosides A-C, together with one known pregnane glycoside, stephanoside B, from the stems of M tinctoria.
