Anti-asthmatic and bronchodilator activity
Adhatoda has been used in traditional medicine to treat respiratory disorders. Both vasicine and vasicinone, the primary alkaloid constituents of Adhatoda are well established as therapeutic respiratory agents .
Extracts of Adhatoda‟s leaves and roots are useful in treating bronchitis, and other lung and bronchial disorders, as well as common coughs and colds. A decoction of the leaves of Adhatoda has a soothing effect on irritation in the throat, and acts as an expectorant to loosen phlegm in the respiratory passages.
Vasicine, the main alkaloid of Adhatoda vasica showed anti-inflammatory activity.
The anti-tubercular activity of Adhatoda vasica was studied by Barry (Barry et al., 1955). Adhatoda vasica has a growth inhibitory effect on Mycobacterium tuberculosi (Grange et al., 1996). A chemical constituent of Adhatoda alkaloids, vasicine, produces bromhexine and ambroxol two widely-used mucolytics. Both of these chemicals have a pH-dependent growth inhibitory effect on Mycobacterium tuberculosis.
Indirect effects of Adhatoda on tuberculosis include increased lysozyme and rifampicin levels in bronchial secretions, lung tissue and sputum, suggesting that it may play an important adjunctive role in the treatment of tuberculosis.
