Abstract: An excipient and a method for manufacturing concentrated Chinese herbs through using the excipient are provided. The manufacturing method includes the following steps: (a) providing a Chinese herb raw material; (b) obtaining an extract from the Chinese herb raw material; (c) collecting volatile oils in a separate bin, later reintroduced; (d) removing water from the extract, to get a concentrate; and (e) adding an excipient to the concentrate, and then granulating and drying, to get a Chinese herbal preparation, in which the excipient contains a capsule protective agent of 1-99 wt % with respect to the excipient and a decomposed product of starch of 1-99 wt % with respect to the excipient. Therefore, the amount of starch required to be used is reduced and the manufactured concentrated Chinese herbal preparation can be completely dissolved in water.
