Whenever acupuncture is to be performed, the pulse must first be diagnosed to differentiate between deficiency and excess. If the Qi of the five Zang organs is exhausted both internally and externally, needling will result in death. When both pathogenic factors and healthy Qi are deficient, and the pulse is small, acupuncture should not be used; instead, sweet medicines should be employed for regulation, as detailed previously. In cases where both pathogenic factors and healthy Qi are excessive, a pure reducing method should be applied. If pathogenic factors are excessive while healthy Qi is deficient, reduction should precede tonification. Reversing the methods of tonification and reduction will exacerbate the disease. The principles regarding men being treated by reducing the exterior and tonifying the interior, and women by tonifying the interior and reducing the exterior, have also been detailed earlier. Improper application of tonification and reduction, whether excessive or insufficient, can also cause harm. For instance, when pathogenic factors are excessive and healthy Qi is deficient, the sensation at the needle tip when pathogenic factors arrive is tight and rapid, whereas when Gu Qi (Grain Qi, representing healthy Qi) arrives, it feels slow and mild. If the practitioner fails to analyze these sensations correctly and continues to use reducing techniques after Gu Qi has arrived, it will deplete the Ying Qi (Nutritive Qi), which is the refined essence derived from food and water. This is referred to as "hitting the target but failing to remove the pathogen leads to leakage of essence; leakage of essence causes the disease to worsen." Conversely, if both pathogenic factors and healthy Qi are excessive, and the pathogen has not yet been fully expelled while Gu Qi has not yet arrived, the needle sensation remains urgent. In such cases, reducing techniques should continue until the pathogen is completely eliminated. If the practitioner is unclear about the sensations under the finger and needle and withdraws the needle abruptly, residual pathogens may accumulate internally, potentially leading to carbuncles or sores. This is described as "harming the center and withdrawing leads to stagnation of Qi; stagnation of Qi generates carbuncles and sores." Practitioners must exercise extreme caution. This summarizes the general hazards of acupuncture.
The *Ling Shu: Jing Fa Shi Pian* states: "Reversing tonification and reduction exacerbates the disease." The *Nan Jing: Difficulty 78* states: "Men should reduce the exterior and women tonify the interior; failure to obtain De Qi indicates ten deaths for every one cure."
Twelve Prohibitions for Acupuncture:
(1) Reducing the exterior in men leads to loss of Qi.
(2) Tonifying the interior in women leads to loss of Qi.
(3) Do not needle immediately after sexual intercourse; do not engage in intercourse immediately after needling.
(4) Do not needle when intoxicated; do not drink alcohol immediately after needling.
(5) Do not needle when angry; do not become angry immediately after needling.
(6) Do not needle when fatigued; do not exert yourself immediately after needling.
(7) Do not needle when full; do not eat heavily immediately after needling.
(8) Do not needle when hungry; do not remain hungry immediately after needling.
(9) Do not needle when thirsty; do not remain thirsty immediately after needling.
(10) In cases of great fright or terror, wait until the Qi stabilizes before needling.
(11) For patients arriving by carriage, allow them to lie down and rest for approximately the time it takes to eat a meal before needling.
(12) For patients arriving on foot, allow them to sit and rest for approximately the time it takes to walk ten Li before needling.
