Since ancient times, the Chinese nation's reverence and love for jade have not been limited to its gentle and understated physical properties and aesthetic value. Deep within our culture, jade has been endowed with the sacred power to connect heaven and earth and nurture life. This profound belief, in the eyes of ancient physicians, transformed into an unremitting quest to explore the medicinal value of jade. Among the great synthesizers, Li Shizhen's Bencao Gangmu (Compendium of Materia Medica) of the Ming Dynasty stands out. This monumental work not only recorded plant and animal medicines but also included jade, revealing its unique status as a "medicinal stone."
The story begins in the distant prehistoric era. In the Neolithic Liangzhu culture sites, a large number of exquisite jade artifacts were unearthed. They were not only symbols of power but were also believed to possess mysterious effects such as warding off evil, bringing good fortune, and even curing diseases. Ancient people observed the toughness, warmth, and unique energy of jade formed over billions of years in nature, and began to try to apply it to medicine. The earliest records can be traced back to the Shanhaijing (Classic of Mountains and Seas), which describes certain jades as having the effects of "wearing it prevents confusion" and "eating it prevents hunger." Although mysterious, it reflects the ancient people's initial understanding of the medicinal value of jade. By the Han Dynasty, although Zhang Zhongjing's Shanghan Zabing Lun (Treatise on Cold Damage and Miscellaneous Diseases), the medical sage, did not directly mention jade as medicine, his use of mineral medicines undoubtedly laid the foundation for later physicians to explore the medicinal properties of jade.
It was Li Shizhen's Bencao Gangmu that truly systematized and scientifically organized the medicinal value of jade. In this encyclopedic medical masterpiece, Li Shizhen meticulously recorded the properties, flavors, meridians, efficacy, and indications of various jades. He classified jade as part of the "Metal and Stone Department," believing that it has a "sweet taste, neutral nature, and is non-toxic," possessing numerous effects such as "clearing internal heat, relieving vexation, moistening the heart and lungs, aiding the voice, nourishing hair, nourishing the five zang organs, tranquilizing the soul, benefiting blood vessels, and brightening the eyes and ears." For example, he mentioned "jade powder"—powdered jade—which could be used to treat "vexing heat, diabetes, asthma, and palpitations." There are even records of ancient people holding jade pieces in their mouths to promote salivation, quench thirst, and clear heat and detoxify. This meticulous observation and generalization of the medicinal properties of jade reflect Li Shizhen's rigorous scholarship and profound understanding of traditional medicine.
The records of jade in Bencao Gangmu were not unfounded but were based on long-term clinical practice and folk experience. Ancient people believed that jade contained the essence of heaven and earth, and its trace elements and physical properties could produce subtle biological effects when in contact with the human body. For example, modern scientific research shows that some jades contain beneficial trace elements such as zinc, selenium, and magnesium, which may be absorbed by the human body through skin contact or internal consumption (jade powder) under certain conditions, thereby playing a certain health-care role. Of course, the ancient understanding of "qi" and "energy" differs from modern scientific explanations, but their core idea is to harmonize the body's yin and yang through the inherent properties of jade to achieve disease prevention and fitness.
In Chinese culture, jade is not only a material existence but also a spiritual sustenance. It symbolizes nobility, purity, auspiciousness, and eternity. Regarding jade as a "medicinal stone" is not only an ancient exploration of the medicinal properties of all things in nature but also a deep concern for life and health. This concept of "nurturing life with jade" is still prevalent among the people today. Many people wear jade ornaments, believing that jade can "nourish people" and ward off evil and ensure safety. This includes both psychological comfort and a simple belief in the traditional efficacy of jade. The combination of jade culture and traditional Chinese medicine theory demonstrates the unique philosophy of life of the Chinese nation: the unity of heaven and man, conforming to nature, and achieving health and longevity through harmonizing body and mind.
In modern society, how should we inherit and develop the wisdom of jade in Bencao Gangmu? This is not to encourage everyone to blindly consume jade powder, but to deeply explore the scientific principles and cultural connotations behind it. We can use modern scientific and technological means to analyze the mineral composition, physical properties of different jades, and their possible effects on the human body. At the same time, we must cherish the value of jade as a cultural heritage and protect those jade artifacts that carry historical memory and traditional wisdom. Let the gentle, tough, and understated spirit of jade be integrated into our lives, advocating a healthy, harmonious, and coexisting lifestyle with nature. Let the jade in Bencao Gangmu be not just a record on a page, but a symbol of Eastern wisdom that lives in the present and gently benefits the world.
