Waiguan TB-5 is a very important point. Some practitioners claim that it is able to expel all six Pernicious Evils (Wind, Heat, Cold, Dampness, Dryness and Fire). However, it is more widely used for removing Wind-Heat and releasing it from the Exterior. Typical symptoms are ear pain, fever, sore throat, slight sweating, aversion to cold and a Floating-Rapid pulse.
However, it is also widely indicated for Lesser Yang Stage when the Wind-Heat penetrates the Defensive Qi. It is half in the Exterior and half in the Interior, with manifestations like alternation of chills and fever, irritability, hypochondrial pain, bitter taste, blurred vision and a Wiry pulse.
This point is also able to treat Painful Obstruction Syndrome of the arm, elbow, wrist, finger, shoulder and neck, especially if the Obstruction is caused by Wind Invasion. It is effective in all the sinew and muscles along the Channel due to its Connecting-Luo point characters.
Furthermore, Waiguan TB-5 benefits the ears. When Exterior Wind-Heat invades the ears, it may cause an ear infection with symptoms such as tinnitus, deafness, ear pain, itching or swelling.
Waiguan TB-5 clears Heat in the Head as well, which leads to symptoms such as redness, pain and swelling of the eyes, stiffness of the tongue, mouth ulcers, cracked lips, nosebleed and mumps.
Finally, it subdues Liver Yang Rising, so as to treat dizziness, neck pain or headache (especially migraine headache).
