Garlic has been referred to as ‘nature’s antibiotic’. It is a powerful cleanser of the body and regular ingestion promotes a healthy heart and circulation by lowering blood pressure and cholesterol. It also helps fight infection and can boost immunity. There is strong evidence to suggest that garlic helps with the prevention of cancers of the  digestive system, including the oesophagus, stomach, colon and rectum. Those who  don’t like the taste of garlic should try the odourless supplements that are available.
