Wrightia tomentosa Roem. & Schult., also known as W. arborea (Dennst.) Mabberley, is a plant belonging to the Apocynaceae family. It is native to regions such as Punjab, Rajasthan, Bihar, Assam, and the Western Peninsula. In Ayurvedic medicine, it is referred to as Kutaja (red-flowered) and Indrayava for its seeds. In Siddha/Tamil medicine, it is known as Pala.
This plant has two varieties mentioned in Ayurvedic texts: the male variety is mostly associated with Holarrhena, while the female variety is associated with Wrightia. In Unani medicine, Holarrhena antidysenterica (Conesse Bark) is referred to as Inderjao Talkh (bitter), and Wrightia tinctoria (Dyer’s Oleander, Blue Dyeing Roseberry) is known as Inderjao Shireen (sweet).
The dried bark of Wrightia tomentosa is used as a substitute for Holarrhena antidysenterica bark. Both barks contain the active principle alkaloid conessine. Other alkaloids found in the bark include conessine dihydrate, holarrhine, kurchicine, and a small amount of conkurchine. The bark also contains beta-sitosterol, lupeol, alpha-amyrin, and reducing sugars in addition to the alkaloids. Wrightiadione, an isoflavone isolated from the stem bark, has displayed cytotoxic activity. Furthermore, two aliphatic compounds, namely n-tritriacont-16-one and hexaconsan-3, 6-diol-12-oic acid, have been isolated from the bark.
