Abstract: A method for making a fiber containing active ingredients from a Chinese herb. The method includes subjecting a fiber material, which is to be combined with active ingredients from the Chinese herb, to be swelled with a solvent of cellulose and then to be impregnated in a solution of an extract of the Chinese herb. The fiber material is a cellulose fiber or a spunlaced nonwoven fabric made thereof. The method requires no use of adhesives. With the method, the fiber material does not need to be subjected to acidic or basic solutions or high temperature, which would cause the active ingredients to be decomposed. The method can provide a cellulose fiber or a nonwoven fabric made thereof, both of which have a higher content of active ingredients from a Chinese herb and higher durability. Furthermore, the method is simple and is easy to control, and thus, suitable for mass production.
