Tribulus terrestris is known by a number of names and is an annoying weed, a shrub that is usually low lying and spreads as ground cover. It is native to southern Europe, Asia and grows in Australia and the US. It contains a substance called Protodioscin and clinical studies have shown that it increases male and female libido and improves sperm count and allegedly cures impotence and erectile dysfunctions. When you read the medical literature this sounds amazing, until you read further, and the studies that claim it is an aphrodisiac and a libido booster have been carried out by those connected to the drug companies which manufacture capsules and pills made with puncture vine extract.

In India it is used as a uro-genital tonic and it is said to help cure cystitis, get rid of kidney stones. On the subcontinent it is used to staunch the flow of blood from a wound, strengthen the kidneys, and treat gout and impotence. It’s also a mild diuretic and apparently good for the prostate gland.

You can’t eat it, but spare a thought for the weed the next time the burrs get in your dog or cat’s paws. It might be good for something after all!
