Embodiment 1

[0130] Embodiment 1: dropping pill

[0131] Prescription: Chonglou 900g, Hypericum perforatum 600g

[0132] The medicinal material of Chonglou is extracted twice with 70% ethanol, the first time is extracted with 10 times the amount of reflux for 2 hours, and the second time is extracted with 8 times the amount (by weight) for 1.5 hours; the extracts are filtered and combined. Centrifuge at a speed of 2500rpm for 30min, take the supernatant, and collect the residue; the supernatant is made of AB-8 resin, the loading concentration is 0.2g / ml, the adsorption flow rate is 2BV / h, the washing volume is 5BV, and the elution volume is 5BV with 30% ethanol. The eluent is 70% ethanol, and the amount of eluent is 5.5BV, and the elution flow rate is 3BV / h; the 70% eluent is combined with the residue, the ethanol is recovered, and vacuum-dried.

[0133] Hypericum perforatum was extracted twice with 80% ethanol, 2.0 hours each time, 10 times the amount; the extracts were filtered and comb...

Embodiment 2

[0137] Prescription: Chonglou 1000g, Hypericum perforatum 600g

[0138] The medicinal material of Chonglou is extracted twice with 70% ethanol, the first time is extracted with 11 times the amount of reflux for 2 hours, and the second time is extracted with 9 times the amount (weight ratio) for 1.5 hours; the extracts are filtered and combined. Centrifuge at a speed of 2500rpm for 30min, take the supernatant, and collect the residue; the supernatant is made of AB-8 resin, the loading concentration is 0.2g / ml, the adsorption flow rate is 2BV / h, the washing volume is 5BV, and the elution volume is 5BV with 30% ethanol. The eluent is 70% ethanol, and the amount of eluent is 5.5BV, and the elution flow rate is 3BV / h; the 70% eluent is combined with the residue, the ethanol is recovered, and vacuum-dried.
