Since ancient times, jade has held a paramount position in Chinese culture, not only symbolizing wealth and status but also embodying the virtues of a gentleman. However, in the vast history of Chinese civilization, the value of jade extends far beyond these aspects. It has also been endowed with mysterious healing powers, becoming an indispensable part of traditional Chinese medicine (TCM) theory. Especially in Li Shizhen's monumental work, "Bencao Gangmu" (Compendium of Materia Medica) during the Ming Dynasty, the medicinal value of jade was meticulously documented, revealing the profound cultural heritage and scientific exploration behind this thousand-year-old medicinal stone.
The story begins in ancient times. Legend has it that as early as the Yellow Emperor's era, there was a saying that "jade is the most beautiful of stones," and it was believed that jade could "ward off evil and calm the mind." The "Shanhaijing" (Classic of Mountains and Seas) also records many peculiar effects of jade, such as "wearing it prevents confusion" and "eating it prevents hunger." While these accounts are mythological, they reflect the ancients' initial understanding of jade's medicinal value. By the Qin and Han dynasties, the practice of using jade in medicine was quite common. The silk manuscript "Fifty-Two Prescriptions for Diseases" unearthed from the Mawangdui Han tombs contains records of grinding jade into powder for treating illnesses. These early practices laid the foundation for the systematic discussion of jade in "Bencao Gangmu."
In "Bencao Gangmu · Metal and Stone Department," Li Shizhen classified jade as a superior-grade substance and meticulously documented its medicinal properties, indications, and usage. He believed that jade was "sweet in taste, neutral in nature, and non-toxic," possessing numerous effects such as "clearing heat from the stomach, relieving shortness of breath and vexation, quenching thirst, moistening the heart and lungs, aiding the voice, benefiting hair, nourishing the five zang organs, calming the soul, and promoting blood circulation." This aligns remarkably with modern medical research on trace elements. Jade contains various trace elements beneficial to the human body, such as zinc, magnesium, and selenium. These elements can indeed promote blood circulation, nourish the skin, and even play an auxiliary role in treating certain diseases to some extent. For instance, the ancients often ground jade into powder for internal or external application. Internal consumption of jade powder was said to "clear heat and detoxify, generate fluid and quench thirst," used to treat febrile diseases with thirst, sore throat, and other symptoms. External application could "astringe sores, promote tissue regeneration, reduce swelling, and relieve pain," used to treat carbuncles, swelling, contusions, and sprains. While modern medicine approaches such therapies with caution, the simple medical ideas and the wisdom of utilizing natural resources behind them are still worth pondering.
"Bencao Gangmu" also particularly emphasized the "health-preserving" effects of jade. Li Shizhen pointed out that long-term wearing of jade could nourish one's "essence, qi, and spirit," thereby achieving longevity. This is not only due to the trace elements contained in jade itself but, more importantly, its cultural significance and psychological suggestion. The warm and subtle quality of jade is often regarded as the demeanor of a gentleman. Wearers are subtly influenced by it, cultivating their character and achieving a peaceful state of mind. This philosophy of "nurturing virtue with jade and nurturing life with virtue" is at the core of traditional Chinese health preservation culture.
Today, although the direct application of jade as a medicine is rare, its cultural significance and auxiliary therapeutic effects are still widely recognized in modern TCM theory and health preservation practices. For example, jade gua sha boards and jade massagers utilize the physical properties and trace elements of jade to promote blood circulation, soothe muscles, and achieve health and wellness goals. Furthermore, the aesthetic value and spiritual solace provided by jade have never diminished. People wear jade ornaments not only for beauty but also to seek inner peace and protection. The combination of jade culture and TCM theory is a crystallization of Chinese wisdom, telling us that all things in nature have their properties, and proper utilization can benefit humanity.
Looking back at history, from the legends of "Shanhaijing" to the systematic treatises of "Bencao Gangmu," and then to modern health preservation practices, jade's healing journey has never ceased. It is not merely a beautiful mineral but a carrier embodying the profound cultural sentiments and life philosophy of the Chinese nation. In the future, with the advancement of technology and deeper exploration of traditional culture, more mysteries of jade may be revealed, and its value in health and wellness will be more scientifically explained and widely applied. This thousand-year-old medicinal stone will continue to illuminate the path to health for the Chinese nation with its unique radiance.
