Boerhaavia diffusa exhibits anti-estrogenic effect; diuretic

Boerhaavia diffusa is a plant of tropical region used in Ayurvedic as well as some other traditional herbal medicines taken for pain relief, anti-inflammation, and treating indigestion. It is also used for its anti-diabetic and diuretic properties. However, animal studies are promising there were no human studies conducted using Boerhaavia diffusa.

Anti-diabetic Activity

Daily oral administration of aqueous solution with 200mg/kg of the leaf Boerhaavia diffusa L. extract was able to significantly reduce blood glucose (50.5%) and significant increase in plasma insulin levels (52.6%) in alloxan-induced diabetic rats [1]. Another study came to comparable anti-diabetic effect using same dose [2]. Orally administered Boerhaavia at a dose of 500mg/kg body weight for a period of 30 days to alloxan-induced diabetic rats exhibited normalized blood glucose and serum insulin levels with a similar potency as a standard hypoglycaemic drug Metformin [3]. There was no effect in non-diabetic rats [3]. Observed anti-diabetic effect is believed to be mediated by increased release of insulin from the existing beta cells of pancreas [2,7] or through extra pancreatic action [7].

Interaction with Liver Enzymes

200 mg/kg of Boerhaavia diffusa leaf extract somewhat improved activities of the hepatic enzymes in experimentally induced diabetic rats (increased hexokinase, decreased glucose-6-phosphatase [G6P], fructose-1,6-bisphosphatase [F1,6P]) [1]. Effect was comparable to 600 microg/kg Glibenclamide [1].

Anti-Estrogenic Effect

One in vitro study demonstrated potent anti-estrogenic properties of methanol extract of Boerhaavia diffusa in MCF-7 breast cancer cell lines [4]. At 100mcg/mL, Boerhaavia methanolic extract exhibited similarly effectiveness as ICI 182-780 (strong estrogen receptor antagonist) on the expression of a selected estrogen responsive gene pS2, however estrogen receptor binding with IC50 at 320+/-25ug/mL is fairly weak [4].

Diuretic Action

Boerhaavia diffusa appears to posses diuretic effect [5] as it was able to further increase diuresis (urination) associated with kidney stone formation in a dose-dependent manner [8]. Leaves and roots seem to have diuretic effect with minimal effects noted when using stem [6].

Other Possible Benefits of Boerhaavia Diffusa

One in vitro study showed that Boerhaavia posseses the ability to reduce kidney stones formation (anti-urolithiasis) and may even reduce the stone size [9]. This was confirmed in animal study in ethylene glycol-induced hyperoxaluric rats [8]. Boerhaavia diffusa (at the dose of 100 and 200 mg/kg body weight orally for 28 days) not only ameliorated hyperoxaluric oxidative stress and renal cell injury in urolithiasis but also prevented kidney stone formation in a dose-dependent manner [8]. One study even reported cortisol lowering activities in male mice [10]. Aqueous extract of B. diffusa roots also exhibits significant free radicals scavenging activity [8]. In alloxan-induced diabetic, 200 mg/kg of B. diffusa leaf extract was able to significantly increase reduced glutathione, superoxide dismutase, catalase, glutathione peroxidase and glutathione S-transferases (GSTs) in liver and kidneys [2]. In thioacetamide intoxicated rats, Boerhaavia (2 ml/kg root) exhibited hepatoprotective activity as visible by protection of a majority of serum parameters, i.e. GOT, GPT, ACP and ALP, but not GLDH and bilirubin [11].

Side Effects and Toxicity

The extract does not show any signs of toxicity up to an oral dose of 2 g/kg in mice [9].
