Yinxi HE-6 is mostly applied to nourish Heart Yin, especially if there are also Empty-Heat symptoms such as night sweating, dry mouth, insomnia, mental restlessness or the feeling of 'steaming bones'. It is often used together with Fuliu KI-7 for this pattern of Heart Yin Deficiency.
In additional to that, as the Accumulation-Xi point of the Heart Channel, it can strongly invigorate the Blood and Qi. Therefore it can treat Blood Stagnation in the chest with typical symptoms like stabbing pain or fullness in the chest as well as palpitations.
Finally Yinxin HE-6 subdues Rebellious Qi so as to avoid Blooding going upward. Thus it can treat vomiting of blood or nose blood.
