Adhatoda is an herb growing on small evergreen shrubs found at lower altitudes in India and South East Asia. The leaf has been used for centuries to treat asthma.

Effect of Adhatoda on Asthma

Adhatoda works as a bronchodilator and mild expectorant. Adhatoda also works by increasing the viscosity of mucous to assist with expectoration. Key constituents of Adhatoda leaf are the quinazoline alkaloids (0.5–2%). The major alkaloid is vasicine present at levels of 45–95% and is the original source of the drug bromhexine, which is often still used to assist expectoration.
