Health Benefits

The most clinically significant health benefit of Cold Coin Grass is the treatment of gallstones and kidney stones, which can minimize the need for surgery. Prolonged use of this herb can reduce the size of kidney stones and allow them to be passed from the body during urination.

Gallstones can form from bile and cholesterol in the gall bladder of some people. They often must be removed surgically, which can result in complications. Gold Coin Grass can reduce the size of gallstones to the point that they become asymptomatic.

A study of the effects of Gold Coin Grass on kidney stones was published in the British Journal of Urology in 1993. Researchers at Kumamoto University, Japan induced kidney stones in two groups of mice. Mice in the control group had an 81 percent chance of developing kidney stones while 29 percent of the mice receiving the Gold Coin Grass extract developed kidney stones.

Side Effects

Gold Coin Grass does not appear to have significant side effects in the dosages typically used in herbal medicine. Some people with kidney stones who take this herb report symptoms such as fever, headaches, muscle pain, nausea and vomiting. However, these symptoms are generally believed to be caused by the stress of passing the stones rather than the Gold Coin Grass itself.
