Reddish-brown clear liquid with spicy smell; mainly used for emergency relief, anti-inflammatory and hemostasis; can treat abdominal pain, rheumatic bone pain, bruises, sprains, cuts, burns, burns, mosquito bites, etc., and some It has a certain effect on discomfort caused by motion sickness, seasickness and dizziness.

In the acute phase of a bruise (within 24 hours), the capillaries around the subcutaneous soft tissue will rupture. At this time, if you use safflower oil and other drugs to promote blood circulation and remove blood clots, it will aggravate the local injury. Blood seepage will not only fail to stop the bleeding, but will also aggravate the bleeding. If the skin at the sprained area is ulcerated, applying safflower oil directly will make the injury more serious or even induce infection.

Not suitable for trauma during the period of local swelling. After human tissue is damaged by external force, it will show an inflammatory reaction. A large amount of fluid will leak out from the blood vessels into the sprained area, causing local swelling, which will then compress the nerves and cause pain.

This reaction usually reaches its peak within 24 hours. If safflower oil is used at this time, it will accelerate local blood circulation and increase leakage. Not only will it not have a therapeutic effect, but it will aggravate local swelling and pain. At this time, you should rest, elevate the affected limb, and apply cold compress immediately to help the blood vessels contract and reduce swelling and pain. Wait 24 hours, then apply safflower oil to reduce inflammation, disperse stasis, and relieve pain.

At this time, local cold compress should be applied to the sprained area to promote hemostasis. After the bleeding stops, apply safflower oil and other drugs to reduce swelling.

It is not suitable for wounds with broken skin, because safflower oil contains a large amount of volatile components and is highly irritating. If it is applied directly when the skin is broken, it will make the injury more serious and even induce infection.

It should not be used by women during menstruation. Because drugs such as safflower oil that promote blood circulation, remove blood clots, and unblock collaterals have blood-activating effects. Physiological changes during the menstrual period will affect the bleeding and coagulation mechanisms of the human body. The self-physiological regulation of the endometrium causes the endometrium to release more tissue active substances during the menstrual period, thereby increasing the body's bleeding tendency. If women use blood-activating drugs without authorization, it may cause iron deficiency anemia, causing symptoms such as dizziness and pale complexion.
