Flaxseed oil is known to cleanse the body from within, and is also used topically to get a smooth and clear complexion. It not only detoxifies the body from within but also helps clear blemishes, reduce acne scars and pigmentation marks. One of the greatest advantages of flaxseed oil is that it helps the digestive system to function properly and smoothly. Modern research has also found evidence to suggest that flaxseed can help control sugar levels, reduce the risk of cancer and contributes to maintaining a healthy heart.
