This Chapter is a dialogue from The Yellow Emperor's Classic of Internal Medicine, specifically Chapter 61, "The Spiritual Pivot – The Five Prohibitions." The Yellow Emperor questions Qi Bo about acupuncture contraindications, outlining five prohibitions (days to avoid needling specific body parts), five depletions (conditions where draining techniques are forbidden), five oppositions (disagreements between symptoms and pulse), and nine appropriations (understanding needle types). The exchange details specific circumstances where acupuncture should be avoided to ensure patient safety and effective treatment. The text provides a foundational understanding of ancient Chinese medical practices and cautions concerning acupuncture.
