Graviola 500 mg - 100 Capsules
Graviola (Soursop) is a small, upright evergreen tree, 5-6 m high, with large, glossy, dark green leaves. It produces a large, heart-shaped, edible fruit that is 15-23 cm in diameter, is yellow-green in color, and has white flesh inside. Graviola is indigenous to most of the warmest tropical areas in South and North America, including the Amazon. The fruit is sold in local markets in the tropics, where it is called guanbana in Spanish-speaking countries and graviola in Brazil. The fruit pulp is excellent for making drinks and sherbets and, though slightly sour-acid, can be eaten out of hand.
Graviola (Soursop) has a long, rich history of use in herbal medicine as well as lengthy recorded indigenous use. In the Peruvian Andes, a leaf tea is used for catarrh (inflammation of mucous membranes) and the crushed seed is used to kill parasites. In the Peruvian Amazon the bark, roots, and leaves are used for diabetes and as a sedative and antispasmodic. Indigenous tribes in Guyana use a leaf and/or bark tea as a sedative and heart tonic. In the Brazilian Amazon a leaf tea is used for liver problems, and the oil of the leaves and unripe fruit is mixed with olive oil and used externally for neuralgia, rheumatism, and arthritis pain. In Jamaica, Haiti, and the West Indies, the fruit and/or fruit juice is used for fevers, parasites and diarrhea, and as a lactagogue; the bark or leaf is used as an antispasmodic, sedative, and nervine for heart conditions, coughs, grippe, difficult childbirth, asthma, asthenia, hypertension, and parasites.
Originally listed by the National Cancer Institute in the USA in 1976, it was not until 1995 that work gained any momentum.
The NCI now supports the Purdue research. Recently this has confirmed that extracts from Graviola leaves killed cancer cells ´among six human-cell lines´ and were especially effective against prostate and pancreatic cancers. Another study showed their effect against lung cancer.
The most recent study by the Catholic University in South Korea has shown that the active ingredients have ´selective cytoxicity´ comparable with Adriamycin, a drug historically used for breast and colon cancer. A further study published in the Journal of Natural Products claimed Graviola was 10,000 times more effective; a third study from South Korea showed that, unlike Adriamycin, there was no negative activity on healthy cells; whilst a fourth study from Purdue (1997) stated that many cancer cells which survive classic chemotherapy by developing resistance to chemicals, were attacked none-the-less by the Graviola agents.
Dr Jerry McLaughlin, Purdue´s lead researcher says that many cancer cells, over time, develop a P-glycoprotein pump to expel the chemotherapy agent before it can work. However Annona chemicals bypass this and kill the cancer cell. Dr McLaughlin has a number of videos published on the web about his findings.
