Preparation method of vernonia anthelmintica compound silver nanometer colloid

The invention relates to a preparation method of a vernonia anthelmintica compound silver nanometer colloid, comprising the following steps of: firstly preparing an extracting solution of vernonia anthelmintica; then uniformly mixing the extracting solution of the vernonia anthelmintica with a silver nitrate solution; and reacting at room temperature or by heating in water bath or adding into a sodium hydroxide solution for oscillating reaction at the room temperature so as to obtain the vernonia anthelmintica compound silver nanometer colloid. The vernonia anthelmintica compound silver nanometer colloid obtained by using the preparation method is directly used in the fields of medicine and health, compounds the functions of the heat clearing, the deswelling, the disinfestation and the tinea treatment of the vernonia anthelmintica and the characteristics of the diminish inflammation and the disinfection of silver nanometer particles and is expected to bring the enhanced drug effect for the treatment of skin d
