The invention relates to a production technology of Ganoderma lucidum blood-purifying toxicity-removing stomach-invigorating cancer-resisting body-building health care liquid. According to the production technology, special nutrient solution for Ganoderma lucidum is sub-packaged into a non-toxic glass or plastic culture vessel; in a clean room, a special strain for Ganoderma lucidu is added into about 100kg of the nutrient solution for Ganoderma lucidum according to a ratio of about 20 to 60%; the nutrient solution for Ganoderma lucidum is placed at a temperature of about 30 DEG C for culturing; when the gloss of the nutrient solution in the culture vessel is faded and the nutrient solution has specific fragrance of Ganoderma lucidum (patients suffering from symptoms such as sub-health, constipation, stomach swelling pain and indigestion, body fatigue and disability, or dizziness and the like drinks about 100 to 150ml per time, and after about 1 to 6 hours, faeces toxicity starts to be removed, the symptom feelings are alleviated, or an effect is obvious), culture can be ended. In the production, traditional Chinese medicinal materials do not need to be added. Adoption of the technology has the characteristics of low investment, simple and convenient process technology, time saving, energy saving, environmental protection, short production period, high content of active ingredients, high activity, good effects, high yield and benefits and the like. The production technology is suitable for developers in the fields of bio-pharmaceuticals, health care products, a health club, a tea room and a tea house, a rehabilitation aged-care center and a high-tech bio product to apply.
