Garlic, affectionately known as the “stinking rose,” has been called the most promising anti-cancer agent we have to date. The same elements that give garlic its powerful scent also give it the disease-preventing power.
Garlic appears to have antimicrobial and immunostimulating properties and may give some relief of symptoms of colds or upper respiratory problems. This occurs as garlic stimulates the mucus-producing vagus nerve reflexes.
You can find garlic in a variety of forms, including fresh, powder, and pills, however, raw garlic may be the most potent.
