The sea buckthorn plant originated in the Himalayas and is widely used in health products and cosmetics. The oil extracted from sea buckthorn provides the polyunsaturated omega 7 fatty acids as well as omega 3 (alpha linolenic acid), omega 6 (linoleic acid) and omega 9 (oleic acid). Relatively few plant species are good sources of these essential fatty acids. The sea buckthorn plant originated in the Himalayas and is widely used in health products and cosmetics.
