Adhatoda vasica Nees

Justicia adhatoda, commonly known in English as Malabar Nut, Adulsa, Adhatoda, Vasa, or Vasaka,[1][2] is a medicinal plant native to Asia, widely used in Siddha Medicine, Ayurvedic and Unani systems of medicine.[3]

The plant's range includes Sri Lanka, Nepal, India, Pakistan, Indonesia, Malaysia, and China, as well as Panama where it is thought to have been introduced.[3]

Botanical description[edit]

J. adhatoda is a shrub with lance-shaped leaves 10 to 15 centimeters in length by four wide. They are oppositely arranged, smooth-edged, and borne on short petioles. When dry they are of a dull brownish-green colour. They are bitter-tasting. When a leaf is cleared with chloral hydrate and examined microscopically the oval stomata can be seen. They are surrounded by two crescent-shaped cells at right angles to the ostiole. The epidermis bears simple one- to three-celled warty hairs, and small glandular hairs. Cystoliths occur beneath the epidermis of the underside of the blade.

Chemical composition[edit]

Several alkaloids are present in the leaves. The most important is vasicine, a quinazoline alkaloid.[3] The vasicine yield of the herbage has been measured as 0.541 to 1.1% by dry weight.

Pharmacology[edit]

This shrub has a number of traditional medicinal uses in Siddha Medicine, Ayurvedic and Unani systems of medicine.[3]

Vasicine, the active compound, has been compared to theophylline both in vitro and in vivo.[4] Another, vasicinone, showed bronchodilatory activity in vitro[5] but bronchoconstrictory activity in vivo.[6] Both the alkaloids in combination (1:1) showed pronounced bronchodilatory activity in vivo and in vitro.[7] Both alkaloids are also respiratory stimulants.[7] Vasicine has a cardiac–depressent effect, while vasicinone is a weak cardiac stimulant; the effect can be normalized by combining the alkaloids.[7][8] Vasicine is reported to have a uterine stimulant effect.[8] Vasicinone was shown to have an antianaphylactic action.[8] Clinical trials of a commercial drug containing vasicinone and vasicinone have not revealed any side effects while treating bronchial asthma.[9]

Cultural reference[edit]

It is the Unofficial provincial flower of the Punjab province of Pakistan.

Names[edit]

It is also called Adhatoda vasika, which is derived from a former scientific name. It has different names in different Indian languages.[10]
