Chanca Piedra




Chanca Piedra; Wild-harvested from the Amazon Jungles.

Chanca Piedra is a whole plant herb that is known to remove kidney stone, gallbladder stones, clean the liver, and help lower blood sugar levels in some cases.

In 1990, Nicole Maxwell reported that Dr. Wolfram Wiemann (of Nuremburg, Germany) treated over 100 kidney stone patients with chanca piedra obtained in Peru and found it to be 94% successful in eliminating stones within a week or two.

The Paulista School of Medicine in São Paulo, Brazil, conducted studies with humans and rats with kidney stones. They were given a simple tea of Chanca Piedra for 1–3 months and it was reported that the tea promoted the elimination of stones.1 They also reported a significant increase in diuresis and sodium and creatine excretion. Subsequently the medical school educated new doctors about the ability to treat kidney stones with this natural remedy and now it is found in many pharmacies throughout Brazil. In a 1999 in vitro clinical study, a chanca piedra extract exhibited a potent and effective inhibitory effect on the formation of calcium oxalate crystals (the building blocks of most kidney stones)

Chanca Piedra’s traditional use for hypertension has been explored by research as well. The hypotensive effects were first reported in a dog study in 1952 (in which a diuretic effect was noted also).6 The hypotensive effects were attributed to a specific phytochemical in chanca piedra called geraniin (an ellagitannin phytochemical) in a 1988 study.10 In 1995 Indian researchers gave human hypertensive subjects chanca piedra leaf powder in capsules and reported a significant reduction in systolic blood pressure, a significant increase in urine volume, and in urine and serum sodium excretion.11 Chanca piedra’s diuretic effect in humans was recorded as far back as 192912 and, in India, a tablet of chanca piedra (called Punarnava) is sold as a diuretic there.13 In the above 1995 study, researchers also reported that blood glucose levels were reduced significantly in human subjects studied.11 Two other studies with rabbits 14 and rats 15 document the hypoglycemic effect of chanca piedra in diabetic animals.

Yet another study documented Chanca Piedra with aldose reductase inhibition (ARI) properties.16 ARIs are substances that act on nerve endings exposed to high blood sugar concentration to prevent some of the chemical imbalances that occur and thus protect the nerve. (This activity also supports Chanca Piedra’s traditional use for diabetes). This ARI effect was attributed, in part, to another ellagitannin phytochemical—ellagic acid—found in chanca piedra. This well-studied phytochemical has been documented with many other beneficial effects in numerous clinical studies (over 300 to date)
