Patoli is a common Indian medicinal plant. It is a medium-sized deciduous tree having straight stems and a height of 9-18 m. The tree has spreading branches and its bark is fairly smooth, thick, and of yellowish-grey colour. The leaves of the tree are simple pinnate, having a length of 30-45 cms and they also have 3-5 pairs of leaflets. The leaves are elliptic-oblong or obovate to lanceolate and they are acute to long caudate-acuminate at apex. The base is acute or rounded, often unequal-sided and the margins entire or shortly serrate. There are 8-10 pairs of main nerves and the petiolules of lateral leaflets are usually 1-1.3 cm long. The leaves and inflorescences of the plant are nearly or quite glabrous. The aromatic flowers of Patoli are borne in slender, lax, drooping terminal panicles and the calyx has a length of 6mm. The calyx is campanulate, usually purple and shortly 3-5 toothed.

A native to India, Patoli is most commonly found throughout the country at an altitude of about 1200 m, chiefly in deciduous forests. The Ayurveda practitioners consider the root, flowers and fruits of the tree to have the same properties and uses as those of Stereospermum che-lonoides.
Therapeutic use:

  • Its fresh root bark is juicy and bitter and a decoction of the bark is considered to be useful for treating asthma and relieving cough and excessive thirst.
  • The Indian people reportedly use a decoction of the leaves for treating chronic dyspepsia. Both the decoctions of the root and leaves of this Indian medicinal plant are credited with antipyretic properties.
  • A mixture of the juice of this plant’s leaves and lime is used as a sedative.
  • If the juice of the leaves is boiled with oil, it is used in the treatment of rheumatism and diseases of the ears and teeth.
  • The flowers and fruit are used to relieve scorpion stings.
