The invention discloses a method for recycling Chinese patent medicine production waste decoction dregs. The method comprises the following steps: chopping the decoction dregs after the extraction of the Chinese medicinal plant into blocks with the length of between 4 and 6cm, packaging the blocks into a plastic bag, sealing the bag, fully decomposing the decoction dregs for 40 to 60 days, and taking the decomposed decoction dregs as a substrate for the soilless culture of Chinese medicinal plants, vegetables or fruit seedlings. Compared with the prior art, the decoction dregs can be used as the substrate for the soilless culture of the Chinese medicinal plants, vegetables or fruit seedlings after the decomposition, thereby making full use of the nutrient contents in the decoction dregs, avoiding the pollution of the Chinese medicinal plants, vegetables and fruits caused by the heavy metals and pesticides in the soil, opening up an economical cycle way for producing green Chinese medicinal plants, vegetables and fruits, and saving the land resources needed by the burying of the decoction dregs.
