Although the germ only constitutes 3% of the weight of a wheat grain, it contains nearly 25% of the protein, vitamins and minerals. The oil is very high in vitamin E and essential fatty acids and because of its high vitamin E content, which is a natural antioxidant which helps to prevent rancidity, it is often added to other carrier oils to help lengthen their shelf life and to prevent them from expiring.
When it is applied topically onto the skin, it helps promote the formation of new cells, improve circulation, and to help repair sun damage to the skin. It is also used to help relieve the symptoms of dermatitis.
Though the consistency of wheatgerm oil is too sticky and heavy to use on its own, it can be mixed with another carrier oil. A small percentage can be used with mixing with a massage oil or when preparing a carrier oil blend.
