Many scientists throughout history have been convinced in the healing properties of the linseed, including the father of medicine, Hippocrates. The linseed and the linseed oil are the most important source of nutrients in the entire food chain. The cold pressed linseed oil hastens metabolism, burns up fat faster and is the only oil that actually helps to reduce body weight.

The linen also contains vitamins indispensable in producing these essential fatty acids.
