The invention discloses fructus forsythiae granules and a traditional Chinese medicine preparation thereof. The fructus forsythiae granules are prepared through the method comprising the following steps that fructus forsythiae decoction pieces are taken, 2-5 times of water is added, distillation by heating is conducted for 1-3 h, volatile oil and aromatic water are collected and included by beta-cyclodextrin to obtain beta-cyclodextrin inclusion, and a medicine liquor is filtered for standby application; medicine residues are decocted 2-3 times by adding water, each time of decoction is conducted under heating for 1-2 h by adding 5-10 times of water, the medicine liquors are mixed; filtrate is concentrated into clear cream with the relative density of 1.02-1.12, and the clear cream is screened with a 250-350-mesh sieve when the cream is still hot; the clear cream is spray-dried to obtain spray-dried powder; the beta-cyclodextrin inclusion and the spray-dried powder are mixed to be uniform, and dry granulation is conducted to obtain the fructus forsythiae granules with the grain size of 16-40 mesh. According to the fructus forsythiae granules, the preparation technology is simple, technological parameters are easy to control, and a scientific and fast detection method with the high controllability is achieved.
