'Gaohuang' refers to the space between the Heart and diaphragm, and it is supposed to be the most difficult part of the body any medical treatments can reach. Thus Gaohuangshu BL-43 is often used in chronic diseases with great debility.
First of all, it tonifies the Original Qi and general Qi of the whole body and is indicated for patients after a long-term illness. Direct moxibustion with moxa cones is more recommended in this case.
Secondly, it strongly nourishes the Lung Yin, that is depleted after chronic Lung disease. The patient normally suffers from chronic dry cough, wheezing, coughing of blood, exhaustion, night sweating, consumption and weight loss. In this case, moxa is not recommended.
Thirdly, it nourishes the Essence in case of Kidney Deficiency, especially after a long-term disease, characterized by symptoms such as nocturnal emissions, seminal emissions, impotence, low sexual energy or poor memory.
Fourthly, it nourishes the Heart and invigorates the Mind. It achieves so by promoting the Essence's function of benefiting the Brain. Therefore, BL-43 is able to improve memory and lift the general spirit.
