Chuan hyssop is often used to draw fire downward.
According to the different places of origin, hyssop is divided into Chuan hyssop and Huai hyssop, both of which have the effects of promoting blood circulation and menstruation, inducing fire to go downward, tonifying the liver and kidney, strengthening the tendons and bones, and inducing diuresis and lymphatic flow, but Chuan hyssop focuses on activating blood circulation and removing blood stasis (to promote blood circulation and eliminate stasis of blood within the body), facilitating joints and inducing fire to go downward; Huai hyssop focuses on tonifying the liver and kidney, and strengthening the tendons and bones, therefore, it is used more often in Chuan hyssop to induce fire to go downward.
Chuan Niu Knee is used to draw fire downward (inhibit the rise of fire in the kidneys), mostly in raw form, and is used for heat symptoms in the head and face, such as vomiting blood, nosebleeds, swollen and painful gums, sores on the mouth and tongue, and dizziness and headache. It is contraindicated in pregnant women and those with excessive menstruation, and used with caution in those with weak spleen and stomach and frequent diarrhea. Adverse reactions include diarrhea and abdominal pain.
If medication is needed, it should be used under the guidance of a traditional Chinese medicine practitioner, and individuals should not take medication on their own.
