Ancient Marquis Tomb Yields China's Oldest Steel Acupuncture Needles

In a remarkable archaeological discovery, China's oldest steel acupuncture needles, dating back over 2,000 years, have been unearthed from the burial site of the Marquis of Haihun in Jiangxi Province. This finding is significant as it provides insight into the advanced medical practices of ancient China.

The needles were crafted through sophisticated puddling steel technology, a testament to the metallurgy skills of the Han Dynasty, which flourished from 202 BC to 220 AD. They were located inside a jade tube that had been stored within a gold-foiled lacquer box. Unfortunately, the burial conditions led to corrosion and fragmentation of these historical artifacts.

According to Yang Jun, the lead archaeologist on the excavation team, at least five needle-like objects were visible within the jade tube's cross-section. This meticulous crafting suggests a refined approach to medical instrumentation used in ancient times.

The needles are measured to be between 0.3 and 0.5 millimeters in diameter. It is believed that these needles were wrapped in cloth before being placed into the jade tube, ensuring both hygiene and easy handling during medical practices.

"This is unequivocally a medical instrument," stated Wang Chuning, a doctoral researcher at Peking University, emphasizing that the fineness of these needles closely resembles that of modern acupuncture needles used today.

Experts have pointed out the advantages of using steel over other materials like iron, gold, and silver in the making of acupuncture needles. Steel offers greater durability and efficacy, which are critical factors in medical applications.

According to Gu Man of the China Academy of Chinese Medical Sciences, these needles represent the earliest known steel acupuncture needles found in China, providing vital evidence for understanding the evolution of steel metallurgy and ancient medicinal practices of the Western Han Dynasty.

This significant discovery not only enriches the historical narrative of acupuncture and Chinese medicine but also highlights the technological prowess of ancient civilizations in metallurgy and healthcare.
