Abstract: To make diacylglycerol obtained by adding an emulsifier contain both an effective oil-soluble component and an effective water-soluble component which are contained in herbal medicines, a herbal medicine component for promoting the absorption of the oil-soluble component in the small intestine and a production method thereof are objects of the present invention. The powder of the herbal medicines is added to solvent oil selected from diacylglycerol and/or triacylglycerol cooking oil to which lecithin and/or a W/O type emulsifier are added, is heated and an herbal medicine component is extracted or dissolved. By such a method, drugs and healthy food which contain all effective oil-soluble and water-soluble components contained in the herbal medicines and which promote the absorption of the oil-soluble components in the small intestine can be produced.

Abstract: A method for solubilizing in water a refractory element not soluble in water can be a method of adding a refractory element to material water obtained by solving a solubilizer, and finely grinding the refractory element using a homogenizer. However, the mechanical method of grinding using a homogenizer cannot evenly particulate the element, and it is difficult to obtain a translucent solubilizing liquid which is stable for a long period. When an ethanol solution obtained by solving a refractory element is mixed with material water, the ethanol solution is instantaneously dispersed, and the refractory element is particulated into colloidal particles. When a solubilizer solution obtained by solving a solubilizer in water is added to the colloidal solution and gently stirred, the particle is bound to the solubilizer to obtain a translucent solubilizing liquid which is stable for a long period.

Abstract: One species or a mixture of a plurality of species of turmeric, which are made to contain a water content and dried after being irradiated with a far infra-red ray, is soaked in cooking oils and fats. A far infra-red ray is further irradiated, so that oil-soluble ingredients are dissolved. As a result, active ingredients, which are easy to be absorbed in intestines, are generated from the raw turmeric, the oil-soluble ingredients of the turmeric, such as curcumin, essential oil, etc. are dissolved in the cooking oils and fats to facilitate the absorption in intestines, and an offensive smell and a bitterness, which are peculiar to turmeric, are removed.
