The invention discloses a method for preparing an enzyme bath material by probiotic solid fermentation technology. The method comprises the following steps of: 1, preparing an enzyme fermentation material, i.e. uniformly mixing a plant raw material, a nutritional material, hot water at the temperature of 60 to 100 DEG C in a ratio of 100:1-5:80-150 to prepare the enzyme fermentation material; and2, preparing the enzyme bath material, i.e. adding seed liquor into the enzyme fermentation material in a ratio of 1 to 5 percent, uniformly mixing the mixture, piling the mixture for fermentation and preparing the enzyme bath material when the temperature of the enzyme fermentation material reaches 60 to 70 DEG C. Probiotics utilized by the method belong to thermophilic bacteria and the heat from the growth of the probiotics can keep the temperature of enzyme bath over 60 DEG C. The fermentation heat can stimulate a human body to sweat, promote blood circulation, accelerate the metabolism ofcells in the body, improve the detoxification capability in the body, expand pores, promote cutaneous respiration and absorption of nourishment, and keep skin elasticity. The probiotics can also restrain the growth of pathogenic bacteria and makes bath more natural, comfortable, nutrient and healthy.
