Benefits of Garlic for Preventing or Treating Infections
Applying
garlic gel products may help to treat certain fungal skin infections, such as athlete's foot, jock itch, or ringworm. Keep in mind that garlic can be irritating to the skin and can cause significant damage if applied topically. It doesn't seem to provide much benefit for people infected with
Helicobacter pylori (
H. pylori), a type of bacteria that may contribute to ulcers. Early research does suggest that garlic may help prevent the
common cold.
Is Garlic Beneficial for Diabetes?
Garlic does not seem to have much of an effect on blood sugar in people with or without
diabetes. Therefore, it probably is not effective for treating this condition.
There are a few different active components in garlic, including allicin, ajoene, and S-allyl-L-cysteine. Some forms of garlic have more of these active components than others. For instance, freeze-dried preparations contain very little allicin.
For treating
high cholesterol, garlic is believed to work by decreasing the production of
cholesterol in the liver. It may have antioxidant effects, which may protect the blood vessels from hardening. It also has several effects that "thin" the blood, perhaps reducing the risk of blood clots, but which may also increase the risk of bleeding. For
treating high blood pressure, garlic may help to relax the blood vessels and cause them to dilate (open wider), actions that may help
lower blood pressure.
Garlic may also have antibacterial, antifungal, and anticancer benefits.
Garlic is safe for children when consumed in normal food amounts. However, it is not clear if
garlic supplements are safe for use in children. Do not give your child garlic supplements without the approval of your child's healthcare provider.
