pedicel, mint and other medicinal materials. The
traditional Chinese medicine composition is prepared by loading a functional natural eutectic
solvent concentrated solution on matrix
medicine powder. The preparation method comprises the following steps: carrying out supercritical CO2 extraction on
menthol to form a
menthol-
choline chloride natural deep-eutectic
solvent, carrying out synergistic treatment on part of medicinal materials by the
solvent to obtain a functional natural deep-eutectic solvent concentrated solution, carrying out
superfine grinding on the rest medicinal materials to prepare matrix medicinal

powder by adopting a
fluidized bed, and carrying out
freeze drying to obtain the
menthol-
choline chloride deep-eutectic solvent. Finally,
