We generally divide plasters into two kinds: the first one, which is made of western medicine. Its main ingredient is a cream made of painkillers, which can be used topically to reduce the risk of some gastrointestinal tract and liver function damage brought about by oral medication because of the large amount. The second, mainly some Chinese poultices, even including some Tibetan poultices, can also be used. It mainly plays the role of activating blood stasis and strengthening bones, and can also relieve the patient’s pain. However, no matter which ointment is used, it is necessary to pay active attention to the patient’s skin condition, and stop using it immediately if there is redness and swelling of the skin, or even allergy. After using the cream for more than a week, if the symptoms are still not relieved or even aggravated, it is recommended to go to a specialist hospital for active further treatment.
