Abstract: A method for isolating and/or culturing cambium stem cells of panax ginseng is disclosed. The method comprises a step of treating tissues containing panax ginseng cambium with a compound of formula I. The present application further relates to cambium stem cells of panax ginseng obtained according to the method and use of such cambium stem cells in preparing a product for a suspension culture of panax ginseng. The method for isolating and/or culturing cambium stem cells of panax ginseng according to the present application can effectively separate the cambium stem cells of the panax ginseng which have unlimited cytodieresis ability and strong anti-adversity ability, can provide a basis for ultra-large volume liquid culture, which can significantly reduce production costs.

Abstract: A far infrared anion complex sanitary napkin/pad comprises in sequence from upper to lower layer a web layer, an absorbent layer, a waterproof coating layer, an adhesive layer, a floral essential layer and a far infrared anion fiber layer. The floral essential layer is a paper/fabric layer soaked with extracted floral essential solution. The far infrared anion fiber layer is woven of fiber obtained by mixing anion mother grain, far infrared mother grain, and homopolymer carrier or spinning liquid. The anion mother grain is made from nano grade mineral powder that activates anion in the air. The far infrared mother grain is made from nano grade mineral powder that activates far infrared. The advantages of the sanitary napkin/pad include disinfection, sterilization, anti-inflammation, skin benefits, deodorization and prevention of various gynecological diseases, and also promotes oxygen level carried by anion, minimizes the irritation of the essential solution to the skin.
