How effective is it?
Natural Medicines Comprehensive Database (The Comprehensive Database Natural Medicines) rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate.
The effectiveness ratings for this product is:
Possibly effective for …
High blood pressure. Some research suggests that garlic can reduce by 7% to 8% blood pressure in people with high blood pressure. Also seems to lower blood pressure in people with normal blood pressure. Most studies have used a specific product garlic powder (Kwai, Lichter Pharma).
The “hardening of the arteries” (atherosclerosis). As people age, the arteries tend to lose the ability to taper and flexibility. Garlic appears to reduce this effect.
Preventing colon cancer, rectal cancer and stomach cancer. The eating garlic appears to reduce the risk of developing these cancers. Garlic supplements, however, does not seem to offer the same benefit.
Tick bites. Scientists have compared the number of tick bites among people who take high doses of garlic and those who do not eat garlic. High doses of garlic in the diet, for a period of about 5 months, it appears to reduce the number of tick bites.
Fungal infection of the skin (including ringworm, jock itch and athlete’s foot). Ringworm and Jock Itch respond to treatment with garlic gel containing 0.6% ajoene (a chemical in garlic) and applied to the skin. For athlete’s foot you need a garlic gel with a higher concentration of ajoene (1%). Indeed, the gel with 1% of ajoene appears to be as effective as athlete’s foot medication Lamisil.
Possibly ineffective for …
Diabetes. Taking garlic does not seem to have any effect on blood sugar, either in people with diabetes or those without diabetes.
The treatment of an infection caused by bacteria called H. Pylori can cause ulcers. The use of garlic by mouth for infection with H. pylori looked promising because laboratory tests showing activity against H. pylori. However, when using garlic cloves, garlic powder or garlic oil in humans appears to have some beneficial effect for treatment of persons infected with H. pylori.
High cholesterol. It has been many studies – some better than others – to measure the effectiveness of garlic in lowering cholesterol and other fats called triglycerides. The results have been mixed. But, if one takes into account only high quality studies, researchers have concluded that garlic does not significantly lower cholesterol levels and triglyceride levels.
Breast cancer. Taking garlic does not appear to reduce the risk of breast cancer.
Lung cancer. Taking garlic does not appear to reduce the risk of lung cancer.
Leg pain when walking due to poor blood circulation in the legs (peripheral arterial disease or (EAP). Taking garlic, for up to 12 weeks, there appears to help people with this condition wings.
Insufficient evidence to rate effectiveness for …
The benign prostatic hyperplasia (BPH). There is preliminary evidence that taking garlic orally may help improve urine flow, reduce urinary frequency and other symptoms associated with BPH.
The common cold. Preliminary research suggests that garlic may decrease the frequency and the number of colds when taken for prevention.
Corns. Preliminary studies suggest that applying certain garlic extracts to corns on the feet twice daily produces improvement. An extract of garlic that dissolves in fats produces an effect after only 10-20 days of treatment, while a water soluble extract can take up to 2 months prior to show improvement.
High blood pressure during pregnancy (pre-eclampsia). Some preliminary clinical evidence suggests that taking 800 mg / day of a specific garlic extract (Garlet) during the third trimester of pregnancy does not reduce the risk of developing preeclampsia in women at high risk.
Prostate cancer. The men in China who eat about a clove of garlic a day appear to have a 50% lower risk of developing prostate cancer. It is not known whether this same benefit is applicable to men from Western countries.
Warts. Preliminary evidence suggests that once daily apply garlic extract fat soluble to warts on hands warts removed in 1-2 weeks. Garlic extract soluble in water also appears to help but after 30 to 40 days of treatment.
How does it work?

Garlic produces a chemical called allicin. This seems the garlic makes work for treating certain conditions. Allicin is also responsible for the odor of garlic. Some products can be made “odorless” garlic aging, but this process can also be made less effective. It’s a good idea to look for supplements that are coated (enteric coated) so that they dissolve in the intestine and not the stomach.
Is there concern for the safety of its use?

Consuming Garlic is LIKELY SAFE for most people. The garlic can cause bad breath, a burning sensation in the mouth or stomach, heartburn, gas, nausea, vomiting, body odor and diarrhea. In general, these side effects are worse if used raw garlic. Garlic may also increase the risk of bleeding. There have been reports of bleeding after surgery in people taking garlic. Have also been reported cases of asthma in people who work with garlic and may also produce other allergic reactions.
When used on the skin, garlic is POSSIBLY UNSAFE. When used on the skin as a thick paste, garlic can cause skin damage similar to a burn.
Special warnings and precautions:
Pregnancy and lactation: Garlic is LIKELY SAFE for most women who are pregnant if taken in amounts normally found in food. Garlic is POSSIBLY SAFE during pregnancy and breast-feeding when used in medicinal amounts. There is not enough reliable information about the safety of using garlic on the skin if you are pregnant or breastfeeding. Be careful to avoid use.
Children: Garlic is POSSIBLY SAFE for children if taken orally and appropriately for a short time. But garlic is POSSIBLY SAFE when taken in high doses. Some sources suggest that high doses of garlic may be dangerous and even fatal to children, but the reason for this warning is not known. There are no reports available to report any significant adverse events or cases of child deaths associated with the use of garlic orally.
Bleeding Disorder: Garlic, especially fresh garlic may increase bleeding.
Have stomach or digestive problems: Garlic can cause irritation of the gastrointestinal (GI) tract. If you have stomach or digestive problems Use with caution.
