Patient discussion about Allium sativum

Q. Is garlic helpful in heart ailments? I have heard that garlic is very good for cardiac health and using in curries or cooked with foods will be helpful. I have also heard that it has anti-inflammatory substances and also helps in weight loss. Is garlic helpful in heart ailments?

A. It acts as antioxidant and reduces the amount of free radicals in your body. It’s helpful once taken raw. But the raw garlic can cause bad breadth and blistering of skin and diarrhea. So, there should be a reduced intake of raw garlic. It’s better to have garlic in a cooked up form like in curries or with vegetables. This will also give the desired benefits of garlic and the side effect of over consumption of garlic will also be reduced.
