room temperature; decocting for two times with 1 hour for each time, and combining the decoctions of the two times; adding
gelatin according to a ratio of 5.0g of the
gelatin to 200ml of the decoction to prepare a
gelatin solution; performing
ultrasonic oscillation at 60 DEG C for 5-10 times with 30-60 seconds for each time; performing suction
filtration and defoaming, and then spreading the gelatin solution into a uniform layer of which the thickness is 0.3mm;
drying at 70 DEG C; and
cutting the uniform layer into pieces, and irradiating the pieces with
ultraviolet light for 0.5-1 hour to obtain the Chinese medicinal plaster. The Chinese medicinal plaster is good in
