Sun Simiao discussed in the *Qianjin Fang* (Essential Prescriptions Worth a Thousand Gold): The Gao Huang acupoints (Gao Huang, BL-43/BL-44) can treat all diseases. They primarily manage emaciation and deficiency exhaustion, nocturnal seminal emission, rebellious Qi with cough and asthma, manic confusion, and forgetfulness or errors.

Acupoint location method: Have the patient sit upright, bend the spine, and extend both hands, placing the arms in front of the knees. Align the thumb of the extended hand with the knee cap. Support the elbow with an object to prevent arm movement. Palpate from the upper angle of the scapula down to its lower end. Between them are four ribs and three intercostal spaces; moxa the middle space. Locate the empty space between the ribs on the inner side of the scapula, approximately one finger-width away from the scapula edge. Rub the space between the tendons on the surface of the pectoralis major muscle. Pressing here should produce a sensation of traction extending to the Jian Jing acupoint (GB-21). Moxa one cone on each side of the mid-scapular region, accumulating up to 600 cones, or as many as 1,000 cones. At this point, one should feel Qi descending smoothly like flowing water. Phlegm turbidity should also be expelled. If there is no stagnant phlegm or old disease, nothing will be discharged. If the condition has been prolonged and severe, preventing the patient from sitting upright, have the patient lie on their side, pull one arm forward to locate the acupoint for moxibustion. Alternatively, a general method to find the acupoint is: use the right hand to press from above the right shoulder; the spot unreachable by the fingertips is the acupoint. The same applies to the left hand. Then apply moxibustion using the previous method. If the patient cannot sit upright for long or frequently extends their arms, they may lie prone on a cloth pad, extend both arms, and have someone help separate the two scapulae. Otherwise, the scapulae will cover the acupoints, making them inaccessible. The cloth pad used for lying must remain fixed in size and position; otherwise, the accurate acupoint location will be lost. After this moxibustion treatment, the person's Yang Qi will become robust and vigorous. One should adjust and nourish oneself accordingly to restore physical balance. The acupoints are located near the fifth thoracic vertebra. Referencing standard measurements, they are located bilaterally three cun lateral to the lower border of the fourth thoracic vertebra.

Discussion states: In ancient times, Qin Huan failed to cure the Marquis of Jin because the disease was located above the "Gao" (heart fat) and below the "Huang" (diaphragm fat), areas beyond the reach of acupuncture and herbal medicine. This refers to these acupoints. People at that time lacked skill and could not locate these acupoints, so chronic ailments were difficult to dispel. If one uses careful and convenient methods to locate and moxa these points, no disease will remain uncured. Wang Weiyi stated in the *Mingtang Tongren Jiu Jing* (Illustrated Manual of Acupuncture and Moxibustion on Bronze Figures): The Gao Huang acupoints are located bilaterally three cun lateral to the lower border of the fourth thoracic vertebra. They treat all conditions, including emaciation and deficiency exhaustion, nocturnal seminal emission, rebellious Qi with cough, mania, and amnesia. Another method for locating the acupoints: Have the patient sit upright, bend the spine, and extend both hands, placing the arms in front of the knees. Align the thumb of the extended hand with the knee cap. Support the elbow with an object to prevent arm movement. Palpate from the upper angle of the scapula to its lower end. There are four ribs and three intercostal spaces; moxa the middle space. From the inner side of the scapula, about one finger-width away, rub the intercostal space superficially. Pressing should produce a sensation of traction in the shoulder. Moxa one site in the middle of each scapular region, accumulating 100 cones, or up to 500 cones. One should feel Qi descending like flowing water. Discharge should occur. If phlegmatic diseases are present, everything can be expelled. If the patient is too weak to sit upright, have them lie on their side, pull the upper arm forward to locate the acupoint for moxibustion. Use the right hand to press from above the left shoulder; the unreachable spot is the acupoint. The same applies to the left side. Then apply moxibustion using the previous method. If unable to sit for long, extend both arms and have someone separate the scapulae. Otherwise, the scapulae will cover the acupoints, rendering moxibustion ineffective. After this moxibustion, the person's Yang Qi becomes robust. Adjust and nourish oneself accordingly.
