Chanca piedra is a plant that grows wild in the Amazon Rainforest and other tropical areas of the world. Also known as quebra pedra, the name translates to “stone breaker” or “shatter stone,” which comes from its ability to eliminate kidney stones and gallstones from the body. The plant contains stone-like berries underneath its leaves. This makes it a good example of morphism, where a plant’s shape signals its effective bodily use.
While indigenous inhabitants of the Amazon have been using chanca piedra for generations to eliminate kidney stones and gallstones, scientific researchers have been validating the herb’s effectiveness in eliminating kidney stones since the 1980’s. Chanca piedra helps to relax urinary muscles, thus, making it easier to expel kidney stones. Studies in 1999, 2002, and 2003 showed that chanca piedra prevented the formation of the building blocks of kidney stones. These results hinted at chanca piedra’s ability to inhibit the re-occurrence of kidney stones in people with a history of the problem.
In 1990, a German Doctor used Peruvian chanca piedra on 100 kidney stone patients and reported it to be 94% successful in eliminating kidney stones in one to two weeks. Also, in 1990, the Paulista School of Medicine in São Paulo, Brazil conducted chanca piedra studies on humans and rats with kidney stones. The humans and rats were given chanca piedra tea for one to three months. The results showed that the tea not only helped to eliminate the kidney stones, but also increased urination and sodium and creatine excretion. This study convinced medical practitioners of chanca piedra’s effectiveness in eliminating kidney stones and is a main reason why chanca piedra is available today (as quebra pedra) in pharmacies throughout Brazil.
While chanca piedra is most notable for its effect on kidney stones and gallstones, it has been traditionally used in South America, India, Malaysia and the Caribbean to treat colic, diabetes, malaria, dysentery, fever, flu, tumors, jaundice, vaginitis, gonorrhea, and dyspepsia. Natives use the herb to relieve pain, expel intestinal gas, stimulate and promote digestion, and expel worms. Clinical studies have validated these and other uses of the herb. Most notable is the research done on chanca piedra’s effect on fighting hepatitis B, hypertension, diabetes, lowering cholesterol, and detoxifying and normalizing the liver.
For instance, in 1995, Indian researchers reported reduction in systolic blood pressure in hypertensive subjects and a reduction in blood sugar levels in hyperglycemic subjects given chanca piedra leaf powder in capsules. In 2002, Indian researchers reported that chanca piedra lowered blood cholesterol levels in rats as well. In the above 1995 study, human subjects given chanca piedra also experienced increased urination and sodium excretion. This diuretic effect in humans was recorded in India as far back as 1929, where chanca piedra tablets are sold as diuretics under the name Punarnava.
Another area of research has focused on chanca piedra’s pain-relieving properties. In 1996, Brazilian researchers found a plant chemical in chanca piedra to be seven times more potent than aspirin or acetaminophen in mice. This pain-relieving effect is thought to be a reason why humans taking chanca piedra for kidney stones report such quick relief long before the stones are expelled.
Chanca piedra’s liver-protective properties have also been validated repeatedly. Indian researchers reported that chanca piedra was effective in treating children with jaundice, and British researchers reported that children afflicted with acute hepatitis had normal liver function within five days after being given chanca piedra extract. Chinese researchers also reported similar success with subjects with chronic hepatitis who were given chanca piedra.
A much heralded effect of chanca piedra, validated by over 20 different clinical studies, has stemmed from its Hepatitis B-fighting and other anti-viral properties. In 1988, Dr. Baruch Blumberg, winner of the 1963 Nobel Prize for discovering the Hepatitis B (HBV) antigen, reported that chanca piedra could “clear up the chronic carrier state of Hepatitis B.” In 2001, Chinese researchers reported equal effectiveness of 83% between the leading drug, interferon, used for HBV and chanca piedra. The three-month long study was conducted on HBV patients, but the chanca piedra group rated significantly higher in the normalization of liver enzymes and recovery of liver function than the interferon-treated group.
A 1988 Blumberg patent had to do with its ability to inhibit the growth of viruses. It was believed that this property would make it possible for chanca piedra to be effective in treating HIV, sarcoma, and leukemia viruses. Consequently, as a result of a 1992 test tube study, Japanese researchers reported a chanca piedra plant chemical to be toxic to HIV-1 at very small dosages. Likewise, in 1996, Bristol-Myers Squibb Pharmaceutical Research Institute isolated another plant chemical in chanca piedra that was found to have anti-HIV properties, and in 2003, a German research organization reported a 70-75% inhibition of the HIV virus in trials that it conducted.
Empirical data validates many traditional and modern uses of chanca piedra. Overall, the herb is good for assisting the liver in detoxifying the body and in promoting the healthy function of the kidneys and gallbladder. These organs are often compromised by modern stressors of life, such as poor diet, polluted air, chlorinated water, antibiotics, prescription drugs and synthetic hormones. Thus, chanca piedra may be of great assistance in mitigating the effects of modern life stressors through the support it gives to the liver, kidneys, and gallbladder.
