This article from Acupuncture Today explores the essence of acupuncture through the lens of classical Traditional Chinese Medicine (TCM) texts, particularly the Ling Shu. The author, a U.S.-trained practitioner, addresses the common questions of young acupuncturists regarding the power and efficacy of acupuncture, and the reasons behind the variability of acupuncture point effectiveness. The piece highlights a potential gap in U.S. TCM education concerning foundational classical texts like the Huangdi Neijing and Shang Han Lun, despite exposure to diverse acupuncture systems.

By delving into the Ling Shu, the article emphasizes that acupuncture's primary role is to unblock meridians and regulate qi and blood, crucial for overall health and treating various diseases. The text clarifies that the arrival of qi (qi zhi or de qi) is a key indicator of effective needling, rather than simply the act of insertion. Furthermore, the article details the nine classical needle types and their specific functions, ranging from surface regulation to addressing deep blockages. It also explains the various needling techniques described in the Ling Shu, tailored to different syndromes and acupoints, including Zang Fu-based approaches and treatment principles of tonifying deficiency and draining excess. Ultimately, the article underscores that effective acupuncture goes beyond needle placement, requiring skillful engagement of qi and a deep understanding of each technique's purpose, adaptable to modern practice.
