A method for preparing a traditional Chinese medicine composition comprising Ramulus cinnamomi, Poria cocos, Cortex moutan, Radix paeoniae alba, and peach kernel in equal proportions, characterized in that the method comprises following steps: (a) preparation of a Poria cocos powder intermediate: pulverizing 30-49% of the prescription amount of Poria cocos to obtain the Poria cocos powder intermediate; (b) preparation of a paeonol inclusion compound: extracting paeonol from Cortex moutan by direct connection steam distillation, and collecting aromatic water and medicinal dregs for use later; resting the aromatic water for 48-72 hours until crystals are completely crystallized, and filtering and drying in shade to obtain paeonol crystals; and including with β-cyclodextrin to prepare a paeonol inclusion compound; (c) preparation of a Ramulus cinnamomi volatile oil inclusion compound: extracting volatile oil from Ramulus cinnamomi by direct connection steam distillation, adding ethyl acetate extraction during the extracting process, and collecting aromatic water at ethyl acetate layers and medicinal dregs for use later; placing the aromatic water layer in a separating funnel, resting the aromatic water layer, separating an upper ethyl acetate layer, extracting a lower layer with equal amount of ethyl acetate, combining the ethyl acetate layers, carrying out reduced-pressure recovery, and adding ethanol for further concentration to obtain pure volatile oil; including with β-cyclodextrin to prepare the Ramulus cinnamomi volatile oil inclusion compound; (d) preparation of spray-dried powder intermediates of extracts: carrying out alcohol extraction and water extraction on Cortex moutan dregs, carrying out alcohol extraction and water extraction on Ramulus cinnamomi dregs, and carrying out alcohol extraction and water extraction on Radix paeoniae alba, peach kernel, and 51-70% of the prescription amount of Poria cocos; concentrating the alcohol extracts or water extracts separately, combining the concentrated extracts for further concentration to obtain extract, and mixing after spray drying to obtain spray-dried powder; and (e) total mixing: mixing the Poria cocos powder intermediate, the spray-dried powder intermediates of extracts, the paeonol inclusion compound, and the Ramulus cinnamomi volatile oil inclusion compound to obtain the traditional Chinese medicine composition.
