cholesterol after a few months of treatment, but perhaps not enough to reduce heart disease. Garlic is not nearly as effective as regular prescription medicines used to lower cholesterol.
Garlic seems to also lower blood pressure in people with high blood pressure and possibly slow "hardening of the arteries."
There is also some evidence that eating garlic might reduce the chance of developing some cancers such as cancer of the colon, and possibly stomach cancer and prostate cancer. But there is no reliable evidence that garlic is helpful for people who already have cancer.
Some people with diabetes try garlic to help lower blood sugar. But garlic does not seem to be effective for this use.
There isn't enough information to know if garlic is effective for the other conditions people use it for, including: treating a special condition involving high cholesterol in people with HIV/AIDS, earaches, arthritis, allergies, colds, flu, traveler's diarrhea, and others.
