Bacillus Ling oral liquid and preparation method thereof

The invention discloses a bacillus Ling oral liquid and a preparation method thereof. The bacillus Ling oral liquid is mainly prepared from the following raw material components by weight parts: 250-450 parts of rhizoma coptidis, 500-700 parts of baikal skullcap roots, 300-500 parts of gardenia, 200-400 parts of common andrographis herb, 150-300 parts of roots of Chinese pulsatilla and 50-200 parts of liquorice. The preparation method comprises the steps of: mixing the six medicines in uniformity, adding water and decocting for two times; filtering; maintaining the temperature at 55-65 DEG C; decompressing and concentrating into extractum with a relative density of 1.05-1.20g/ml; adding a proper amount of auxiliary materials and 25-40% of sucrose, and stirring in uniformity; adding water to be in 800-2000 parts; settling for 24 hours; adding enough water to be in the original part; and bottling to obtain the bacillus Ling oral liquid. The bacillus Ling oral liquid has the advantages of simple process control, high bioavailability, good effect, high efficacy and low cost.
