[0055] Example 1
[0056] Preparation of antidiarrheal and antipruritic balm for infants and young children:
[0057] (1) Preparation of wild chrysanthemum volatile oil ointment: the wild chrysanthemum is washed, dried, and crushed through an 80-mesh sieve to obtain wild chrysanthemum powder. Put the wild chrysanthemum powder in the extraction kettle, add subcritical fluid dimethyl ether (DME) according to the ratio of material to liquid of 1:8 (g:mL), extraction temperature is 20℃, extraction pressure is 0.5MPa, extraction is 4.5 h Obtain the subcritical initial extract of wild chrysanthemum, the solvent is recovered to the solvent tank by the circulating compressor, recycled, and extracted 3 times, and then the initial extracts obtained 3 times are combined. Finally, the initial extract was spin-dried to dry the solvent dimethyl ether on a rotary evaporator to obtain the wild chrysanthemum volatile oil ointment.

[0080] Preparation of antidiarrheal and antipruritic balm for infants and young children:
[0081] (1) Preparation of wild chrysanthemum volatile oil ointment: the wild chrysanthemum is washed, dried, and crushed through a 70-mesh sieve to obtain wild chrysanthemum powder. Put the wild chrysanthemum powder in the extraction kettle, add the subcritical fluid dimethyl ether (DME) according to the ratio of material to liquid of 1:9, the extraction temperature is 15℃, the extraction pressure is 0.6MPa, and the wild chrysanthemum subcritical is extracted for 5 hours. The initial extract and the solvent are recovered to the solvent tank by the circulating compressor, recycled, and extracted 3 times, and then the initial extracts obtained from the 3 times are combined. Finally, the initial extract was spin-dried to the solvent dimethyl ether by a rotary evaporator to obtain the volatile oil ointment of wild chrysanthemum.
