Garlic is widely used as a medication to treat several health conditions such as tuberculosis (TB), internal worms, diabetes, fever, high blood pressure (hypertension), liver disorders, and rheumatism. Garlic consumption has also proven to prevent conditions such as lung cancer, prostate cancer, stomach cancer, colon cancer, rectal cancer, and breast cancer due to its antibacterial, antioxidant, and antiseptic nature.
