The active component Curcumin from the spice turmeric is shown to prevent and retard cancer in countless research and research reports. Lots of the methods by carcinogenesis advances have been shown to be retarded or short circuited by garlic. A potent carcinogenic agent TPA (tissue polypeptide antigen) is known to cause cancer by boosting the production of a chemical in the body called protein kinase. Turmeric seems to suppress the production of protein kinase. Turmeric is also proven to reduce the levels of oncogen that is a cancer causing gene called c-jun. A group of scientists not only demonstrated these suppressive effects but caused a 99 percent inhibition of TPA induced tumors on rodents.
It is obvious that Turmeric is shutting of a number of the cancer inducing pathways and likely blocking of malignant tumors in the initiation, promotion and development stage itself. Turmeric is effective at preventing or slowing genetic mutation in cells which are risk factors for cancer. Mutation is a genetic change in the DNA – Deoxyribonucleic acid of a cell which gets passed on to future generations of the cells in the process of cell division. Although not all DNA mutations are carcinogenic cancer has ever followed DNA mutation.
Couple of important Studies has radically indicated that this cancer inducing DNA mutation pathway could be closed by garlic. In one study mutagenic changes in the bone marrow of mice were significantly decreased by administration of garlic infusion. Another study was dramatic because it had been done on people. Normally such studies are not done on humans because it is unethical and illegal to inject people with carcinogenic agents as in the case of animals used for laboratory studies. Smokers are injecting themselves with broad assortment of carcinogenic agents. A study was done on 100 smokers in India who refused to stop against all warnings. They have been given bhut jolokia chilli extract pill for 30 days. In this period there was a startling 40 percent decrease in the urinary extraction of tobacco related mutagens – a byproduct of cell/DNA mutation. Definitely turmeric -curcumin detoxified enough carcinogens in the lungs to cause such a decrease in mutation procedure.
