a. "Fry first" should be fried for 15 minutes before adding other medicines.

b. "Later" should be added 5 to 10 minutes before the medicine is cooked.

c. Those who want to "wrap and fry" should wrap it in a cloth bag and put it into the pot to fry together.

d. For "melted" ones, place them in the decoction liquid and add a slight simmer to dissolve them.

e. The medicine that is "taken immediately" is taken with the decoction liquid.

(2) When frying the head and decoction, add cold water 1 to 2 finger widths above the surface of the medicine, and soak for half an hour. The active ingredients will be easily decoctioned. After boiling over high heat, fry over low heat for 20 to 30 minutes. Filter the residue and set aside. When decocting the second decoction, the amount of water should be less, and then boil for 15 to 20 minutes.

(3) The decoction time of different medicinal materials is also different. If the medicine has a firm texture, it should be boiled for 5 to 10 minutes longer; tonic medicines can be boiled for 40 to 60 minutes; medicines that clear away heat and relieve external symptoms should be boiled for 5 to 10 minutes less. The amount of liquid for the first decoction and the second decoction is about one tea cup per cup. Mix it and take it in two portions.
