A simple but effective natural edible oil, the Chinese have been growing soya for more than 4,000 years. Soya oil is light, odourless and contains a valuable source of nutritious fatty acids, and is a versatile emollient and skin moisturiser. This plant has been known and used by the Chinese for more than 4,000 years, though today most of the oil comes from the USA. This oil is a cost-effective base on which to prepare hair and body products where good honest moisturisation is required at a budget price. Soybean is listed as a major starting material for stigmasterol, once known as an anti stiffness factor. Sitosterol, also a soy byproduct, has been used to replace diosgenin in some antihypertensive drugs.
