Embodiment 1

[0024] Preparation of topical plaster:

[0025] Calculated by weight as follows:

[0026] Corydalis: 50g

[0027] Preparation method: (1) Grind borneol into fine powder and set aside. (2) Crush the medicinal material through a No. 1 sieve, add 65% ethanol to soak for 30 minutes at a material-to-liquid ratio of 1:6, reflux at 65°C for 30 minutes, collect the filtrate, and concentrate under reduced pressure to a relative density of 1.07. (3) CMC-Na and tartaric acid were mixed with water and swelled overnight to obtain a transparent and uniform liquid, followed by adding 23mL liquid extract and 0.3g borneol and stirring to obtain phase A. In addition, PAAS, aluminum hydroxide, EDTA and glycerin were mixed and stirred to obtain phase B of the suspension. (4) Then slowly pour phase A into phase B, and with continuous stirring, the matrix will rapidly thicken and harden from liquid. After standing for 4 hours, the particles in the matrix disappeared. At this time, the ...
