Gravi-C is formulated using the following extracts.


There are many studies on Graviola. These studies confirm the following benefits of Graviola.

Cancer studies have shown that graviola helps various types of cancers (breast, colon, lung, pancreatic, prostate, liver) by prohibiting cancer cell division and causing cancer cell death. Further studies have also shown that graviola extract helps cancer tumors by blocking ATP to tumor cells causing cell death while not harming healthy cells.

Graviola extract is effective against multidrug resistant cancer cell lines.

Graviola has been shown to be beneficial for the heart and liver.

Graviola is a natural antimicrobial used to kill bacteria, viruses, parasites and fungus.

Graviola helps the nervous system by calming nerves, relieving stress, improving sleep and lifting depression due to its ability to stimulate serotonine receptors.

Graviola assists the immune system in cleansing abnormal cell/tissue growth.

Graviola helps alleviate muscle and joint pain.

Magnolol, a substance taken from the root and bark of the magnolia tree, is a potent killer of prostate cancer cells, according to a study in the Journal of Cellular Biochemistry. Because it does not damage healthy cells, magnolol could be a promising new therapy for prostate cancer, as well as other types of cancers.

Magnolol, a compound isolated from the root and bark of the magnolia tree, has been used in China and Japan for thousands of years to treat a variety of conditions, ranging from inflammation to ulcers. Recent research suggests that it also slows the growth and triggers the death of cancer cells. Honokiol, a unique compound extracted from magnolia bark, is a potent antioxidant that’s shown in preclinical studies to protect against skin cancer. It’s also a powerful anti-inflammatory and anti-cancer ingredient, natural anti-anxiety aid and effective antibacterial agent.

Researchers at the University of Pittsburgh wanted to learn how effectively magnolol kills cancer cells, and how exactly it triggers cancer cell death. When they treated several different types of human prostate cancer cells with magnolol for 24 hours, they found that the compound both decreased the number of cancer cells, and changed their shape in a way that suggested the cells were undergoing apoptosis (cell death). The treatment worked on many different types of prostate cancer cells, regardless of their invasiveness. The higher the dose of magnolol, the more significant the damage it caused to cancer cells. Meanwhile, magnolol treatment did not appear to harm healthy prostate cells.

The researchers then took their investigation a step further, looking at the pathways by which magnolol affected prostate cancer cells. “It is very important to understand how magnolol acts as an anticancer agent,” says lead author Yong Lee, PhD, Professor in the Department of Surgery and Pharmacology at the University of Pittsburgh. “If we understand the mechanisms of killing (pathways, model of death, etc.), we can improve the efficacy of the drug and avoid side effects.”

Dr. Lee’s team discovered that magnolol alters the activity of various proteins that are involved in the apoptosis process, in order to promote cancer cell death. It also inhibits growth factor receptors that are typically produced in larger-than-normal amounts by cancer cells to help those cells survive.

Its ability to destroy cancer cells without harming healthy cells makes magnolol a promising treatment strategy. Although this study focused on prostate cancer, the treatment may also be useful for other types of cancers.



Sutherlandia frutescens is also known as Cancer Bush or Kankerbos.

Sutherlandia Frutescens, and all the complex compounds that it comprises (the amino acid, L-Canavanine, which has antiviral, anti-bacterial, antifungal and anti-cancer activities. Pinitol, a known anti-diabetic agent, which is used to treat the wasting in cancer - associated with the onset of certain types of cancer - and AIDS patients. GABA, an inhibitory neuro-transmitter, which has been found to lift depression.) What is apparent is that Sutherlandia may have strong benefits to some individuals in the treatment of many of the side effects of cancer as it increases the physical strength and endurance of individuals with cancer, which may assist in the body's ability to fight the sickness.



Silymarin is a flavonoid complex that detoxifies the body and is a strong liver tonic. Silymarin strengthens the body's immune system which makes it effective in fighting cancer by stopping the growth of cancer cells. Research has found that Silymarin destroys prostate, breast, and cervical cancer cells and prohibits cancer cells from attacking other organs; Reduces the side effects of chemotherapy and blocks tumours from starting or continuing to grow.

Amla is rich in antioxidants which help in restricting the growth of carcinogenic cells and is highly effective in preventing the growth of cancerous cells. It helps in keeping harmful free radicals at bay. Antioxidants in Amla can even counterattack the side effects of anti-cancer drugs. Amla increases the oxygen levels in the body and in turn this weakens the cancer cells which die in the presence of oxygen.

Antioxidant, anti-inflammatory and anti-carcinogenic properties of turmeric and curcumin are undergoing intense research which show that curcumin slows the development and growth of a number of types of cancer cells. In Japan researchers defined curcumin as a broad-spectrum anti-cancer agent. Its induction of "detoxifying enzymes," the researchers say, indicate its "potential value ... as a protective agent against chemical carcinogenesis and other forms of electrophilic toxicity. The significance of these results can be implicated in relation to cancer chemopreventive effects of curcumin against the induction of tumors in various target organs" (Iqbal M, et al. Pharmacol Toxicol. 2003 Jan;92(1):33-8).

Scientists at M. D. Anderson, Texas, wrote in January 2003: "Extensive research over the last 50 years has indicated [curcumin] can both prevent and treat cancer. The anticancer potential of curcumin stems from its ability to suppress proliferation of a wide variety of tumor cells. In their latest of a series of reports the M. D. Anderson say: "Curcumin can suppress tumor initiation, promotion and metastasis. Some researchers say curcumin inhibits angiogenesis, i.e. formation of new blood vessels, which tumors use to nourish themselves as they spread (Mol Med 1998 Jun;4(6):376-83).

Gravi-C is a combination of selected herbs that work synergistically to relieve the symptoms and side-effects of cancer and HIV, to strengthen the immune system, increase oxygen levels in the blood and to create a feeling of well-being.

New Studies show that Milk Thistle protects against skin cancer in at least two ways:

  • increases cell death in skin cells that have been damaged by UVA radiation (which comprises 95% of the rays from the sun)

  • increases the repair of sun damaged skin cells from UVB radiation (which comprises 5% of the  rays from the sun)

The immune system’s natural capacity to detect and destroy abnormal cells may prevent the development of many cancers. However, cancer cells are sometimes able to avoid detection and destruction by the immune system when the the immune system is under stress and not functioning properly.
