The time to take the cream is mostly from the winter solstice “one nine” to “nine nine”. Every morning, one spoonful is dissolved in boiling water and taken on an empty stomach. However, since the production of creams must be prepared by a special manufacturer, it takes some time (usually 2 weeks to 1 month) to send the prescription for creams from the doctor to the production line, so it is recommended that patients who need to take creams go to the hospital early to make an appointment for the preparation of prescriptions. Nowadays, there are many small workshops in the market for the preparation of poultices, but they are not qualified, and the poultices will easily become moldy after a long time. Be sure to check whether there is a certificate of qualification issued by the Shanghai Health Bureau.
