The ‘Shenmen’ is an ear acupoint located inside the triangular fossa. First, you need to find the triangular fossa, which requires orientation based on the anatomical structure of the auricle surface. It is a triangular depression formed between the antihelix and the corresponding helix on the antihelix. To find the triangular fossa, you need to know the positions of the helix and the antihelix.

The helix is the curled part of the outer edge of the auricle. The antihelix is located inside the helix, opposite to the antihelix, and is a part of the protruding part of the auricle, resembling the shape of the letter ‘Y’. A part between the upper foot and the helix is a branch of the antihelix upwards. The lower foot of the antihelix is a part of the antihelix, and the depression formed by its branches and the helix is called the triangular fossa. By separating the triangular fossa, the Shenmen point is located one-third above the triangular fossa, closer to the branch of the antihelix. In clinical practice, it is generally necessary to first find the approximate location with a probe, and then press it. In general, in clinical practice, it is necessary to first find one’s own location with a probe, and then make a Shenmen.

It has certain curative effects on insomnia, frequent dreams, hypertension, neurasthenia, epilepsy, and other symptoms, and can be used to treat hypertension, neurasthenia, epilepsy, and other conditions. Auricular therapy generally uses the pressure bead method, commonly using the patch of notoginseng, which can continuously stimulate the acupoints. In clinical practice, in addition to the pressure bead, ear acupoint embedding needles can also be chosen. This is a kind of traditional Chinese medicine physical therapy, that is, embedding the dermal needle in the ear acupoint for auxiliary treatment.
