Embodiment 1

[0016] Cut the whole herb of Asarum into 2cm pieces, put it in a flask, add water (the ratio of Asarum to water is 1:1~10), shake and mix, then heat the flask slowly to boiling, and keep it in a slightly boiling state for 0.5 ~ 2 hours, stop heating, let stand for a while, and filter out the liquid medicine. Collect the medicinal residues after the volatile oil has been evaporated, drain, soak the medicinal residues with 55% to 95% ethanol, heat at 70°C to 90°C for 0.5 to 2 hours, filter out the medicinal liquid, repeat 1 to 3 times, combine the medicinal liquids, After recovering ethanol, dry under reduced pressure to constant weight to obtain a black thick paste.

Embodiment 2

[0018] a. Cut the whole herb of Asarum into 2cm pieces, put it in a flask, add water (the ratio of Asarum to water is 1:1~10), shake and mix, then heat the flask slowly to boiling and keep it slightly boiling After 0.5 to 2 hours, stop heating, let it stand for a while, and filter out the liquid medicine.
