Which acupuncture point is known to treat fever, hypertension, inflammation, and painful disorders?

The ear apex, also known as the apex of the ear or auricular point, is recognized in Traditional Chinese Medicine (TCM) for its significant ability to address various health issues, including fever, hypertension, inflammation, and painful disorders. This acupuncture point is part of the auricular acupuncture system, which is based on the idea that the entire body is represented on the ear. Stimulating the ear apex can help balance the body's energy, promoting a calming effect on the autonomic nervous system and assisting in the reduction of systemic inflammation.

In TCM, the concepts of Yin and Yang suggest that an overactive Yang can contribute to conditions like fever and hypertension, and stimulating the points associated with the ear can help bring balance. Additionally, this auricular point is also beneficial in pain management, making it versatile for treating multiple conditions.

The other options listed do not have the same established range of applications or may correspond to specific protocols that don't fully encompass the broader effects attributed to the ear apex in treating the conditions mentioned.
