An Gui and Cinnamomum cassia are the same kind of Chinese medicine in terms of efficacy, function and so on.
An Gui, also known as Cinnamon, is pungent and sweet in flavor, with great heatiness, and belongs to the kidney, spleen and heart meridians. It has the efficacy of tonifying fire and assisting yang (replenishing the body’s yang qi), inducing fire to return to the source of energy (inhibiting the rise of fire evils in the kidneys), dispersing cold and relieving pain (relieving pain by dispelling the body’s cold evils), and warming and opening up meridians and veins.
Cinnamon can be used to treat various pains, impotence, dizziness and redness of the eyes, abdominal coldness and pain, cold paralysis, blood stasis and menstrual cramps caused by deficiency of kidney yang, deficiency of yang upward (the relative deficiency of yang affecting the head and face), and cold condensation.
Cinnamon should not be combined with lithospermum, and should be used with caution by those with bleeding tendency and pregnant women.
If there is a need for medication, it should be used under the guidance of a doctor to identify the evidence, and should not be used blindly on its own to avoid adverse consequences.
