Which point is known for calming the spirit and relaxing muscles?

The point known for calming the spirit and relaxing muscles is HT-4. This point, also known as "Lingdao" or "Spirit Path," is located on the heart meridian and has significant properties related to emotional well-being. HT-4 primarily aids in alleviating anxiety, palpitations, and emotional disturbance, which directly contributes to a calming effect on the spirit.

In terms of muscle relaxation, HT-4 has effects that can help relieve tension in the chest and promote overall relaxation in the upper body. This dual action makes it particularly useful in cases where both emotional stress and physical tension are present.

In correct context, HT-6, while also related to calming the spirit, focuses more on nourishing the heart yin and addressing night sweats and insomnia rather than muscle relaxation directly. PC-5 is more associated with the treatment of phlegm and related emotional issues such as anxiety rather than muscle relaxation. PC-3 is primarily used for clearing heat and resolving upper jiao conditions, which doesn't specifically target calming the spirit and relaxing muscles in the same manner as HT-4 does. Thus, HT-4 stands out as the specific point for these combined effects.
