The invention relates to the field of drugs, particularly to a
throat lozenge and a preparation method thereof. The
throat lozenge is characterized by being prepared from the following raw materials in parts by weight: 10-30 parts of honeysuckles, 10-14 parts of chrysanthemum, 12-16 parts of

menthol, 4-6 parts of
scaphium scaphigerum, 1-3 parts of radix angelicae, 1-3 parts of longan pulp and 5-7 parts of
peristrophe japonica. The preparation method comprises the following steps: adding water into the raw materials to decoct, removing
drug residues, getting and concentrating liquid supernatant into paste, adding
alcohol after cooling, standing and precipitating, getting and concentrating the liquid supernatant into thick paste, adding
sugar powder and
dextrin to prepare particles; spraying a
menthol solution and pressing into tablets. The
throat lozenge disclosed by the invention has the effects of expelling wind to resolve the exterior, clearing away heat and toxic materials, diminishing
inflammation and relieving pain, dispersing
blood stasis and draining pus, clearing heat from throat, reducing
