Allium is the generic name given to a group of vegetables like onions, garlic, leeks, chives and scallions. Allium is a Latin word for garlic and along with onion they are the commonly found and used members of this group in this part of the world.
These vegetables contain organo-sulphur (allylsulphides) and flavonoids. Onion is especially rich in quercetin and together they contain numerous vitamins and minerals.

Onion has been proven to have anti-inflammatory, cholesterol lowering and antioxidant properties. By its antioxidant properties, it prevents oxidative stress and prevents damage to cells and organs in the body. Onion also contains fibre and it helps in digestive processes and prevents constipation.
Garlic is a more versatile member of this group. It improves the flow of blood through the blood vessels and reduces the tendency of the blood to clot; it breaks down clots in the blood stream. Garlic is therefore a preventive against heart attack and stroke. It is also a vasodilator, it expands the blood vessels and lowers the blood pressure as a consequence. Furthermore, garlic is known to lower cholesterol, triglycerides, and non-beneficial Low Density Lipo-protein (LDL). On the other hand, it increases the beneficial High Density Lipo-protein (HDL) cholesterol in the body.
Garlic also has anti-tumour properties. Studies have shown that garlic reduces the risk of stomach cancer by as much as 50 per cent and colon cancer by 34 per cent. Garlic inhibits the formation of nitrites (a chemical that triggers the formation of cancer) in the stomach. There is also sufficient laboratory evidence that garlic can shrink cancers of the breast, lungs and skin. Other mechanisms by which these allium vegetables carry out their preventive effects against cancer may include the following: their effect on enzyme activities to inhibit production of carcinogens, their ability to stop mutation of cells and their antioxidant action on free radicals.
There is also laboratory evidence to show that they slow down, if not inhibit completely, cell proliferation and tumour formation and growth. Apart from these effects against cardiovascular disease and cancer, the allium vegetables also have antimicrobial, anti-arthritic and hypoglycemic properties. In other words, they can also be effective against infections caused by bacteria and viruses and joint inflammation and pain. They have also been proven to have blood sugar lowering abilities and it is advised that when used with the synthetic hypoglycemic drugs, a lot of caution most be exercised. Indeed, reducing the dose of the drug may be considered.
