Garlic (Allium sativum)

Garlic is a member of the onion family and is nature's most versatile medicinal plant. It has been used all over the world for thousands of years for a wide range of conditions. It has been prized since the first records of civilization for its uses in treating wounds, infections, tumors, and intestinal parasites.

Modern scientists in numerous clinical trials have concluded that it lowers cholesterol, lowers blood pressure, thins the blood (which reduces your risk of heart attack and stroke) and fights bacteria like an antibiotic.
It is a potent antioxidant that has been found to inhibit tumor cell formation and is currently being studied by the National Cancer Institute. It may be effective in fighting stomach, skin and colon cancer.

Though it is best know as a culinary herb and vampire retardant, the medicinal benefits and claims have awarded it the name "Wonder Drug among all herbs".

Modern day research helps explain the broad applications of this "miracle" herb. The bulbs contain the amino acid allicin. When crushed, allicin is released. This chemical element is the component that gives its strong odor, and is responsible for the powerful pharmacological properties of the plant. One medium clove can equal the antibacterial action equivalent to 1% penicillin.

It also contains about 0.5% of an oil that is composed of sulfur-containing compounds. Its sulfur compounds, in addition to Selenium and Vitamins A and C containing compounds, make it a potent antioxidant, protecting cell membranes and DNA from damage and disease.

Although it directly attacks bacteria and viruses, it also stimulates the body's natural defenses against foreign invaders. It is reported to be more effective than penicillin against typhus disease, and works well against strep, staph bacteria, and the organisms responsible for cholera, dysentery and enteritis.

It is generally regarded as a preventative measure for colds, flu and other infectious diseases. Furthermore, scientific studies have shown it stimulates the production of the liver's own detoxifying enzymes which neutralize carcinogens and other environmental toxins. It has also been used to rid the body of intestinal parasites and to treat digestive infections.

Researchers have been studying the anti-cancer properties since the 1940's. It appears that the herb may prevent cells from turning cancerous by enhancing the body's mechanisms for removing toxic substances. Its phytochemicals are believed to enhance immunity and the National Cancer Institute (January 1992) reported that people who ate the greatest amount of onions and garlic had the lowest incidence of stomach cancer. 

Furthermore, it increases the activity of white blood cells and T-helper cells (natural killer cells), the cells that are central to the activity of the entire immune system.

Supplements can improve many of the processes that can lead to cardiovascular disease. It has been used as a blood thinner and anticoagulant to resolve blood clots and improve circulation. It has been shown to lower cholesterol while increasing the level of beneficial HDLs (high-density lipoproteins), the so-called good cholesterol.

The plant has no side effects like those associated with cholesterol lowering drugs. In addition, its compounds gently lower blood pressure by slowing the production of the body's own blood pressure raising hormones. At least seventeen clinical trials have shown that mild hypertension can be effectively managed with the supplement.

It has great value as a long-term dietary supplement, helping to maintain healthy circulation, balance blood sugar and pressure, reduce fat levels in the blood, and improve resistance to infection. It can be taken with conventional antibiotics to support their action and ward off side effects.

It has also been used in treating upper respiratory infections (especially bronchitis), late-onset diabetes, urinary infections, acne, asthma, sinusitis, arthritis, and ulcers.
