A hericium erinaceus stomach nourishing oral liquid and a production method of same. The invention belongs to the technical field of processing of traditional Chinese medicines, and particularly relates to the hericium erinaceus stomach nourishing oral liquid and the production method of same. The method includes the steps of: selecting hericium erinaceus strain from test tube slant, and inoculating the hericium erinaceus strain on a hericium erinaceus fermentation culture medium to culture the strain for 6-8 days to prepare a fermentation liquid; and boiling, filtering, blending, fill-packaging, sealing and sterilizing the fermentation liquid to produce a finish product. Because the main active components in the mycelia and fruiting bodies of the hericium erinaceus are relatively similar, in the invention, the hericium erinaceus fermentation liquid is used for producing the hericium erinaceus stomach nourishing oral liquid instead of fruiting bodies of the hericium erinaceus, so that the process greatly reduces production cost and is convenient to carry out in large-scale industrial production. In addition, during the production, astragalus membranaceus is fermented by means of the hericium erinaceus strain, so that effects of functional components, such as flavones, having stomach nourishing functions in the astragalus membranaceus are improved, and the stomach nourishing effect of the oral liquid is further improved.
