Boerhaavia diffusa is a hardy, low growing vine that has a very generous taproot. The creeping, hairy and sometimes purplish stems yield small red or white flowers. The leaves of this plant are smooth and oblong or cordate in shape.  It spreads rapidly and is often considered an invasive species.

Origin / Habitat

B. diffusa is a prostrate herb found growing in tropical, wet areas, mostly during rainy seasons and is likely native to Brazil as well as India.  It should be noted that a few studies have found that the plant is most effective, medically, when harvested in the month of May [1] [2].

Chemical Constituents

Beta-sitosterol, chlorides, chlorates, hentriacontane, nitrates, potassium nitrate, Punarnavine, sulfates, ursolic acid [2], beta-ecdysone, boeravine, boeravinones, flavons, hypoxanthine-9-L-arabinofuranoside, liridoderdin, punarnavoside, syringaresinol mono Beta-D-glucoside [3] [4].

Plant Part Used

Roots and leaves [4].

Traditional Use

The root of B. diffusa is widely used in Brazilian traditional medicine as a liver tonic and as a diuretic.  Additional uses include as a gallbladder ‘stimulant’, to ease the pain of gallstones and kidney stones, to treat urinary tract infections, kidney disorders and cystitis.  It has also been traditionally used to treat guinea worms.  While much work has been done globally to eradicate guinea worms, they are a common source of ill health in poor areas.  Several countries including Brazil, Guatamala and West Africa use B. diffusa as a treatment for this parasitic infection [4] [5].



B. diffusa is presently being studied for its potential role in diabetes and liver disorders.  Numerous laboratory and animal studies have proven the efficacy of B. diffusa as a hypoglycemic [1] [6] [7].   This is probably due to its regenerative actions upon Beta-cells in the pancreas [8]. One study suggested that the effect of B. diffusa on blood glucose was comparable to glibenclamide [6].

B. diffusa has been used to treat hepatic disorders for thousands of years.  Today there are many studies that verify this claim.  One animal study evaluated the effect of B. diffusa on rats with ethanol-induced liver damage.  The liver damage consisted of increased levels of cholesterol, free fatty acids and triglycerides in the liver and kidneys, all of which were reversed after treatment with B. diffusa [9]. Additional studies have confirmed the usage of B. diffusa as a hepatoprotective [2] with no signs of toxicity [10].

B. diffusa also may play a role in cancer treatment.  Animal studies have shown the effectiveness of using B. diffusa as both a chemopreventive in mice [11] and radioprotective in mice [12].

Animal studies have also confirmed the effectiveness of B. diffusa as a dermatological antifungal.  These studies show that treatment decreases the growth of various species of fungus from the Microsporum genus [13] [14]. Additional research has indicated that B. diffusa, particularly the chemical Punarnavine, has the ability to inhibit the metastasis of certain melanomas in mice [15] [16] [17].

In other research settings animal and pre-clinical studies have showed that B. diffusa exhibits spasmolytic [18] [19], analgesic [20],and immunomodulatory [21] activity.
