Primitively ecological nano processing method for Chinese herbal medicines

The invention discloses a primitively ecological nano processing method for Chinese herbal medicines. The method comprises the following process steps: washing raw and fresh Chinese herbal medicines, smashing the Chinese herbal medicines into slurry at normal temperature, adding the obtained slurry in a vacuum pressure tank and vacuumizing, impregnating at normal temperature in vacuum by using reverse osmosis (RO) purified water, pressurizing to enhance osmosis at normal temperature, suddenly relieving the pressure so that the medicines are bulked, freezing in a refrigerator, smashing ice and breaking to form slurry at normal temperature, performing vacuum dehydration at the temperature of 40 DEG C, and performing vacuum screening to obtain dried nano powder. The method has the advantages of energy conservation, low carbon, primitive ecology as well as capacities of keeping the drug effects of original medicines as much as possible, fully exerting the effects of drug resources and improving sustainable develo
