Promotes optimal liver, kidney and gall bladder function

Gall stones and kidney stones are a major health problem in the United States . In fact, 20,000,000 in the U.S. suffer from gall stones and 600,000 are treated by medical doctors each year for this condition. With the recent introduction of a very well known Amazon rainforest plant, Break-Stone (Chanca Piedra), health care practitioners have acquired a powerful plant ally in helping their patients to maintain optimal kidney, gall bladder, liver, and bladder health.

Traditional Uses

Chanca Piedra is believed to help stimulate the production of bile and to promote healthy liver and gall bladder function. It is also traditionally used to clear obstructions throughout the various internal organs of the body by promoting the elimination of mucous and stones.

In different areas of South America , Chanca Piedra is used to treat a wide variety of conditions. It is used to treat edema and excess uric acid, as well as to treat stones of the gall bladder, kidney, and bladder. In some areas, it is used to treat malaria, typhoid fever, flu, colds, constipation, dysentery, or stomachache. It is also used there, for inflammation of the bowels (IBS), pimples, diabetes, and ulcers.

Chanca Piedra has also traditionally been used for diabetes, prostate disorders, asthma, fever, tumors, bladder infections, as a diuretic, to remove excess uric acid (as in gout), for painful joints, jaundice, indigestion, constipation, vaginitis, viruses of the reproductive tract, proctitis, poor circulation, excessive phlegm, bronchitis, and coughs. It is also considered an anti-spasmodic and muscle relaxant, specific to the urinary tract system.

Traditionally it is also used as an anodyne (pain reliever), apertif (appetite stimulator), a digestive, carminative (helps gas to be expelled from stomach and intestines), and vermifuge (expels worms and other parasites from the intestinal tract), diuretic, and emmenagogue (stimulates menstrual flow).

Doctors’ Experiences In France, Chanca Piedra has been used for some time to treat gall and kidney stones. It is part of a pharmaceutical product called Pilosuryl, which is sold as a diuretic.

Liver Detoxification

Modern life has stressed the liver of the average person. Chanca Piedra can be used, cycling on and off throughout the year, to assist the liver in performing its normal function of detoxification of the body. Liver stressors include eating excessive dairy, meat, and sugar, fried fast foods, processed foods with preservatives, antibiotics, pesticides, drinking water "decontaminated" by chlorine, drinking water containing parasites, the use of hormones in young women as contraception and in menopausal women as a means of preventing osteoporosis and heart disease, the use of steroid hormones to combat chronic inflammatory diseases, and the use of toxic chemotherapies to combat cancer.

Research Findings

In the test system used, the extract of Phyllanthus urinaria showed about four times more potent activity than indomethacin and three times the strength of morphine against the second phase of pain which models the stage of "inflammatory" pain. The pain model used in these tests (formalin-induced persistent pain) appears to provide a state similar to that of post-operative pain in people. ...The pain blockers in Phyllanthus have been identified by the Brazilians as gallic acid ethyl ester and the steroidal compounds as Beta-sitosterol and stigmasterol.

Research in Japan and India in the 1980's has demonstrated the liver -healing properties of Chanca Piedra. The primary compounds responsible are phyllanthin, hypophyllanthin and triacontanal. Glycosides found in Chanca Piedra demonstrated Aldose reductase (AR) inhibitory activity in studies conducted by a Japanese research group in 1988 and 1989.

The analgesic activity of Chanca Piedra was demonstrated in 1994 and 1995 by another research group in Brazil . The diuretic, hypotensive and hypoglycemic effects of Phyllanthus niruri were documented in a 1995 human study , which showed a significant diuretic effect, and a significant reduction in systolic blood pressure in non-diabetic hypertensive and female subjects. Blood glucose was also significantly reduced in diabetic patients taking Chanca Piedra for 10 days. It is also considered an immune system stimulator.

Of particular note, Break-Stone gained world-wide attention in the late 1980's due to the plant's antiviral activity against Hepatitis B. Preliminary clinical trials with P. niruri on children with infective hepatitis using an Indian drug containing Phyllanthus amarus is as the main ingredient showed promising results which fueled the subsequent in vitro and in vivo studies. The in vitro inactivation of Hepatitis B by Break-Stone was reported in India in 1982. A study that followed indicated that in vivo, Break-Stone eliminated hepatitis B in mammals within 3-6 weeks. Several subsequent studies in the late 1980's and early 1990's failed to produce any effect against hepatitis, but other research conducted from 1990 to 1995 has indicated that Chanca Piedra does demonstrate antiviral activity against Hepatitis B. Phyllanthus niruri/amarus is considered, based on accumulated research, as the most effective natural, non-toxic remedy for the Hepatitis B virus, a pathogen now carried by 300 to 500 million people in the world.
