Cooling composition, functional cooling patch and preparation method of functional cooling patch

The invention discloses a cooling composition, a functional cooling patch and a preparation method of the functional cooling patch, the cooling composition comprises lithospermum erythrorhizon and angelica sinensis, and the mass ratio of lithospermum erythrorhizon to angelica sinensis is 1: (0.5-1). When the cooling patch is prepared, the cooling composition is soaked in an ethanol solution, and then decoction and concentration are performed to prepare extract; adding glycerol, polyvinyl alcohol and disodium ethylene diamine tetraacetate into hot water, and uniformly stirring and mixing to obtain a mixture; adding the extract into the mixture, and uniformly stirring and mixing to obtain cooling gel; coating a non-woven fabric with the cooling gel, and then carrying out film molding and shearing, so as to obtain the product, the cooling patch not only can effectively solve the problem that the existing cooling patch is high in irritation, but also has the advantages of physically and quickly cooling, simultane
