Cautions: Adhatoda Vasica is absolutely safe when used in recommended dosages.

Pregnancy and lactation:

Vasaka preparations were studied in rats. A leaf extract with standard Vasicine alkaloid, approximately 0.85%, was used. Adusa (Adhatoda vasica) did not induce abortion in any experiment.

However, in Western science there are no known studies proving the safety of Vasak during breastfeeding and pregnancy.

At the same time Ayurvedic medicine uses Vasaka (Adusa) during pregnancy to reduce the symptoms of nausea, vomiting, acidity along with ginger. Therefore, there is reason to argue about the safety of Adusa during pregnancy and breastfeeding for short-term use.
