According to a study published by "Pharmaceuatical biology", the plant Hygrophila auriculata (K. Schum) Heine. (Acanthaceae) is widely used in the Indian System of Medicine as "Rasayana" for treating brain and liver diseases. In research involving male Wistar rats, a terpenoid rich fraction (TF) from the plant was administered at doses of 100 & 200 mg/kg. This followed a protocol where vitamin E was used at 500 mg/kg for 7 days of drug administration. The study evaluated the plant's potential against transient global cerebral ischemia induced by a 10 min transient occlusion of carotid arteries. Through these methods, the TF from Hygrophila auriculata demonstrated neuroprotective potential against induced oxidative stress.
