Safflower oil and Yunnan Baiyao can be used after an ankle sprain. Both drugs have good blood circulation, blood stasis and pain relief effects, which can well relieve swelling and pain after an ankle sprain, but you must pay attention to the time period of application. Within 24 hours of the early injury, both drugs should not be used, otherwise they will easily aggravate the pain and swelling of the area. After 48 hours of injury, safflower oil or Yunnan Baiyao aerosol can be used externally, but the rubbing and kneading should not be too strong in the process of applying safflower oil, otherwise the soft tissues of the sprained area will be easily damaged. In addition, in addition to the use of these two drugs, you must be careful not to walk on the ground too early. Otherwise, the effect of drug treatment will not be particularly obvious, and may also aggravate the soft tissue damage of the sprained part, so that the symptoms of the disease appear aggravated, and cause the recovery period of the disease to be greatly extended.
