Garlic is a herb that is consumed by many on account of its health benefits. Its antioxidants prevent free radicals that can cause illness and aging and once it has been digested, it converts into sulphur compounds that are anti-cancerous.
It has been used for medicinal purposes for over 5,000 years and for 3,000 of those years it has been used in Chinese medicine. It is a natural antibiotic and was used in both world wars to prevent gangrene in soldiers.
The healing properties of garlic are not an old wives tale or an alternative fad. There has been years of scientific research proving the benefits of garlic, including its abilities to shrink colon cancer tumors.A review of the literature, published in the Journal of Nutrition, states, "One randomized controlled trial reported a statistically significant 29 percent reduction in both size and number of colon adenomas in CRC patients taking aged garlic extract. Five of eight case control/cohort studies suggested a protective effect of high intake of raw/cooked garlic and two of eight of these studies suggested a protective effect for distal colon. A published meta-analysis of seven of these studies confirmed this inverse association, with a 30 percent reduction in relative risk. Eleven animal studies demonstrated a significant anticarcinogenic effect of garlic and/or its active constituents. On balance, there is consistent scientific evidence derived from RCT of animal studies reporting protective effects of garlic on CRC."
The US National Institutes for Health says,"Preliminary human studies suggest that regular consumption of garlic (particularly unprocessed garlic) may reduce the risk of developing several types of cancer including gastric and colorectal malignancies."
Another study concluded that garlic extract reduced the size of colorectal tumors, "Aged garlic extract (AGE) has a suppressive effect on progression of colorectal adenomas in humans. This effect seems to be multifactorial and reduces many risk factors of cancer."
Eating garlic in addition to regular portions of fresh vegetables seems to enhance this positive effect.
