6. It also shows anti-oxidation and hyaluronidase inhibiting activities, with improved moisture holding property.

Alkaloids:
1. It shows both bronchodilatory and bronchoconstrictor activity.
2. It stimulates the respiratory system.
3. It shows a potent anti-inflammatory effect.
4. It possesses abortifacient activities.

Research Information: Extract of Adhatoda vasica shows potent antitussive effect. Studies show it is very helpful to control a cough and intravenously it was 1/20-1/40 on mechanically and electrically induced coughing. (Ref. Dhuley, J.N., Antitussive effect of Adhatota vasica extract on mechanically and electrically induced coughing, J. Ethnopharmacology, 1999, 30:67 (3) 361-365)

Possible Combinations :Adhatoda vasica + glycyrrhiza glabra + emblica officinalis + Tinospora cordifolia (influenza & cough)
