The invention discloses a method for preparing Guangxindanshen Dripping
Pill, which comprises the steps of: (1) extracting
Salvia miltiorrhiza with 75-95%
ethanol, filtering to obtain a filtrate, and recovering
ethanol from the filtrate under reduced pressure; (2) extracting
Salvia miltiorrhiza residue with water or 30-70%
ethanol, filtering to obtain a filtrate, concentrating the filtrate, standing, centrifuging, collecting supernatant, and adsorbing with a resin column; (3) rinsing with water, eluting with 30-70% ethanol, collecting eluate, and recovering ethanol under reduced pressure; (4) extracting
Panax notoginseng with 30-70% ethanol to obtain an extractive solution, filtering the extractive solution, concentrating, standing, filtering to obtain a filtrate, and adsorbing with a resin column; and rinsing with water, eluting with 30-70% ethanol, collecting eluate, and recovering ethanol under reduced pressure; (5) mixing the above medicinal solutions, and concentrating to obtain a
concentrated extract; and (6) mixing the
concentrated extract with a matrix material, stirring, adding
rosewood oil, mixing, sealing, keeping temperature, and making into dripping
pill. The inventive dripping
pill has remarkable improvements in terms of contents of effective ingredients,
