Garlic- In modern times, people are sticking to the adage - a clove of garlic a day keeps cancer away!! Due to its therapeutic properties, garlic has garnered the reputation of being a 'wonder' drug that fights virtually all possible illness ranging from common cold and flue to cancer and plague. Garlic not just keeps cancer at bay but also helps you manage high cholesterol levels. While most people prefer to use organically grown garlic for its high sulphur content, many choose to take garlic supplements in the form of pills and capsules. It is believed that raw garlic is quite effective for treating acne symptoms as well. Moderation is the key here, as consuming garlic in large quantities can cause irritation of the digestive tract and may even damage it.
