The invention discloses a cough relieving extract and preparation method thereof. The preparation method includes the steps: cleaning boat-fruited
sterculia seeds, dasystyle
honeysuckle immature flowers, wild mint herbs, grosvenor
momordica fruits, ural
licorice roots, sea buckthorn fruits, emblic leafflower fruits, ansu apricot seeds,
tangerine peel, lanceleaf lily bulbs, assam tea leaves and common reed
rhizome by weight,
drying and crushing the cleaned raw materials to mix; cleaning pears,
water chestnuts, persimmons and loquats, removing peel and pits of the pears, the
water chestnuts, the persimmons and the loquats,
cutting the pears, the
water chestnuts, the persimmons and the loquats into blocks, performing vacuum
freeze drying on the
cut blocks, crushing the blocks, mixing the raw materials and honey by weight, filling a vacuum
plastic bag with mixture, and preparing the cough relieving extract under
high pressure. According to the method, heat-sensitive
active components can be reserved, so that substances are loose, porous and spongy, sufficient infiltration of the honey is facilitated, structures of
macromolecular substances such as proteins and
starch in medicines change, micro-molecular substances easily permeate, ultrahigh pressure has the function of accelerating aging, the particle
diameter of
emulsion can be reduced, the size of the particle
diameter of dispersion phases of the
emulsion has important influence on stability of paste
emulsion, the quality and the taste of the cough relieving extract can be improved, and effective components are furthest reserved.
