Clinical notes

As its name 'Wind Gate' implies, BL12 is a principal point for expelling pathogenic wind, whether hot or cold. It is essential for the early stages of common colds, influenza, and allergies, treating symptoms like chills, fever, headache, neck stiffness, sneezing, and cough. Its alternate name, 'Heat Mansion' , highlights its ability to clear heat from the upper body. Regular moxibustion on this point is traditionally used to strengthen the body's defensive Qi and prevent recurrent infections.
