Medicinal value of Punarnava:

  • A study was designed to investigate the antihyperlipidemic activity of an aqueous extract of Boerhavia diffusa leaves in alloxan diabetic rats. Oral administration of B. diffusa leaf extract (BLEt) at 200 mg/kg of body weight for 4 weeks resulted in significant reduction in serum and tissue cholesterol, free fatty acids, phospholipids, and triglycerides.
  • Antifungal activity (reduction in colony diameter) of various extracts (pt. ether, chloroform, ethyl acetate, ethyl alcohol and aqueous) of aerial and root parts of Boerhavia diffusa (Nictaginaceae) was screened against dermatophytic fungi Microsporum fulvum. The colony diameter of the target mycelial colony decreased with increasing supplementation of the phytoextract, showing the presence of significant amount of some antifungal phytochemical moiety.
  • Department of Biochemistry, Faculty of Science, Annamalai University, Annamalainagar, Tamil Nadu 608 002, India investigated the effects of daily oral administration of aqueous solution of Boerhavia diffusa L. leaf extract (BLEt) (200 mg/kg) for 4 weeks on blood glucose concentration and hepatic enzymes in normal and alloxan induced diabetic rats. A significant decrease in blood glucose and significant increase in plasma insulin levels were observed in normal and diabetic rats treated with BLEt. Treatment with BLEt resulted in a significant reduction of glycosylated hemoglobin and an increase in total hemoglobin level. The activities of the hepatic enzymes such as hexokinase was significantly increased and glucose-6-phosphatase, fructose-1,6-bisphosphatase were significantly decreased by the administration of BLEt in normal and diabetic rats. An oral glucose tolerance test (OGTT) was also performed in the same groups, in which there was a significant improvement in glucose tolerance in rats treated with BLEt. A comparison was made between the action of BLEt and antidiabetic drug—glibenclamide (600 μg/kg). The effect of BLEt was more prominent when compared to glibenclamide. 
  • An aqueous extract (2 ml/kg) of roots of diameter 1–3 cm, collected in the month of May (Summer), exhibited marked protection of a majority of serum parameters, i.e. GOT, GPT, ACP and ALP, but not GLDH and bilirubin, thereby suggesting the proper size and time of collection of B. diffusa L. roots for the most desirable results.
