Garlic (Allium sativum), a herb used widely as a flavoring in cooking, has also been used as a medicine throughout ancient and modern history to prevent and treat a wide range of conditions and diseases.
1. Treats Acne
This herb may not be found in acne products’ list of ingredients, but it can serve as a natural topical treatment to get rid of blemishes. Allicin, the organic compound in garlic, has the ability to stop the damaging effects of radicals and kill bacteria, according to a 2009 studypublished in the journal Angewandte Chemie. In its decomposed form — sulfenic acid — allicin produces a fast reaction with radicals, which makes it a valuable herb for treating acne scars, skin diseases, and allergies.
2. Treats Hair Loss
A head full of hair that smells like garlic could help in the treatment of hair loss. The herb’s extremely high sulfur content contains keratin, the protein hair is made of. This stimulates fortification and growth. A 2007 study published in the Indian Journal of Dermatology, Venerology and Leprology found the use of a garlic gel added to the therapeutic efficacy of topical betamethasone valerate for alopecia areata treatment can be effective to induce hair re-growth.
3. Fights Common Cold
Garlic’s allicin can serve as a health aid during times of illness. Rene Ficek, a registered dietician and a lead nutrition expert at Seattle Sutton's Healthy Eating in Illinois told Medical Daily in an email: “Garlic cloves contain a healthy dose of allicin, but you may still need a few cloves per day to feel the effects.” However, garlic supplementation can also be used to ward off viruses.
A 2001 study published in the journal Advances In Therapy found a daily garlic supplement can reduce the number of colds by 63 percent compared to not taking supplements. Moreover, the average length of cold symptoms was also reduced to 70 percent, from five days in the control group to 1.5 days in garlic supplement group. These findings suggest the allicin-containing supplement has a protective effect against the common cold.
4. Lowers Blood Pressure
A garlic supplement a day may help keep your blood pressure at bay. Its active compounds can significantly reduce blood pressure comparable to the effects of prescribed drugs. Aged garlic extract between 600 to 1,500 milligrams (mg) was found to be just as effective as the drug Atenolol prescribed for hypertension in a 24-week period, according to a 2013 study published in the Pakistan Journal of Pharmaceutical Sciences.
Garlic is believed to activate the production of the endothelium-derived relaxation factor, according to Ficek, due to the herb’s high amount of polysulfides — sulfur — containing molecules. This leads to smooth muscle relaxation and vasodilation (widening of blood vessels), following the relaxation of the smooth muscle in the vessel wall. Garlic supplements can achieve these effects efficiently without the bad breath compared to raw garlic.
5. Lowers Heart Disease Risk
Garlic can help lower the risk of heart disease by lowering total LDL cholesterol. A 2000 studypublished in the journal Annals of Internal Medicine found the effect of garlic on total cholesterol level in people with elevated levels moderately reduced cholesterol levels.Vandana Sheth, registered dietitian nutritionist and spokesperson for the Academy of Nutrition and Dietetics told Medical Daily in an email that this is achieved by “diminishing the activity of main cholesterol-producing enzyme in the liver.” Garlic supplements can enhance the body’s ability to dissolve blood clots that would otherwise increase the risk of heart attacks by closing the arteries.
