It is certainly possible to use safflower oil after a broken foot, but you should pay attention to the time of using safflower oil. If the foot is just fractured, that is, after the injury occurs, you should immediately brake and apply ice water or ice to reduce the bleeding and swelling caused by local capillary breakage. Wait until the acute period has passed, that is, 24 hours later, you can use safflower oil or external application and local massage to accelerate local blood circulation and reduce swelling. There is also a situation where the foot is broken or bleeding, there is a wound, you should keep the wound clean, avoid the use of safflower oil external application, or local external application, massage, etc., so as not to cause local wound infection and inflammation, so that the condition worsens and difficult to deal with.
