Chinese civilization has long been known as the "Land of Jade." Jade is not merely an exquisite ornament; it is a spiritual object imbued with profound cultural connotations. In the vast treasure trove of Traditional Chinese Medicine (TCM), jade holds a crucial position, and its philosophy of "jade nurturing body and mind" has shone brightly for millennia, continuing to radiate its unique brilliance today.

Our story begins in the distant prehistoric era. In the late Neolithic period, artifacts such as jade pig-dragons and jade owls unearthed from the Hongshan culture sites were not only ceremonial objects but were also believed to possess the power to connect heaven and earth, ward off illness, and dispel evil. At that time, the early people's understanding of jade might have stemmed from its warm touch, resilient texture, and mysterious luster. They observed that people who wore jade seemed to fall ill less often, and rubbing jade on injured areas could alleviate pain. This simple empirical knowledge formed the earliest sprouts of jade medicine.

By the Spring and Autumn and Warring States periods, as the Hundred Schools of Thought contended, medical theories gradually became systematized. Although the "Huangdi Neijing" (The Yellow Emperor's Classic of Internal Medicine), a foundational work of TCM theory, did not directly discuss the medicinal use of jade, its philosophical ideas of "unity of heaven and humanity" and "Yin-Yang and Five Elements" provided a theoretical framework for the later incorporation of jade into medicine. For instance, the warmth and hardness of jade were attributed with "masculine" and "introverted" qualities, aligning perfectly with the balance of the body's internal organs. The mention in the "Shanhaijing" (Classic of Mountains and Seas) that "wearing jade can ward off evil" more directly reflects the ancients' belief in the health benefits of jade.

It was in the Eastern Han Dynasty that the "Shennong Ben Cao Jing" (Shennong's Classic of Materia Medica), China's earliest existing pharmaceutical monograph, truly introduced jade into the pharmacopoeia and systematically expounded its medicinal value. This book listed jade as a superior-grade medicine, believing that "long-term consumption lightens the body and prolongs life." It recorded that jade possesses numerous benefits, such as "clearing internal heat, relieving vexation, moistening the heart and lungs, aiding the voice, nourishing hair, nurturing the five zang organs, calming the soul, dredging blood vessels, and brightening eyes and ears." Here, "jade" broadly refers to various beautiful stones, but primarily soft jade (Hetian jade) and hard jade (jadeite). The ancients believed that jade contains various trace elements, and through long-term wearing or grinding into powder for internal consumption, these elements could be absorbed by the body, thereby achieving the goal of regulating the body and prolonging life. For example, Empress Dowager Cixi often held jade in her mouth in her later years, reportedly to moisten her mouth and maintain her appearance.

In the Tang Dynasty, the Medicine King Sun Simiao, in his "Qian Jin Fang" (Prescriptions Worth a Thousand Gold), meticulously documented various uses of jade, such as "consuming jade powder makes one ageless" and "applying jade powder to the face makes one radiant." He believed that jade could be used both internally and externally, with its essence absorbed through the skin. Li Shizhen's "Bencao Gangmu" (Compendium of Materia Medica) in the Ming Dynasty, a comprehensive compilation, provided an even more complete summary of jade's medicinal value. He categorized jade into jade powder, jade spring (jade liquid), etc., detailing their properties, flavors, meridian tropisms, effects, and main indications. For example, white jade is neutral in nature and sweet in taste, entering the lung and kidney meridians, with the effect of clearing heat, detoxifying, generating fluids, and quenching thirst; green jade is cool in nature and astringent in taste, entering the liver and gallbladder meridians, with the effect of calming the liver, brightening eyes, clearing heat, and dispelling dampness. These records undoubtedly served as authoritative affirmations of jade's medicinal value.

From a modern scientific perspective, the health benefits of jade are not entirely metaphysical. Contemporary research indicates that natural jade indeed contains various trace elements beneficial to the human body, such as calcium, magnesium, zinc, and selenium. With long-term wearing of jade, as the skin rubs against the jade, these trace elements may penetrate the body through the skin, supplementing the body's needs. Simultaneously, the physical properties of jade, such as its warm touch and constant temperature, can also provide a massaging effect on acupuncture points, promoting blood circulation and soothing nerves. For example, jade pillows and jade bracelets are believed to achieve calming the mind, aiding sleep, and promoting blood circulation by physical contact.

Today, the concept of jade health preservation continues. Jade massagers, jade mattresses, jade tea sets, and other products are emerging, combining ancient wisdom with modern technology. However, while pursuing the health benefits of jade, we should also cherish the cultural significance it embodies. Jade is a symbol of the Chinese national spirit and the embodiment of a gentleman's character. It reminds us that health is not merely physical strength, but also peace and harmony of the mind. Wearing a piece of warm jade, feeling its intimate contact with the skin, is not only a care for the body but also a continuation of traditional culture and an aspiration for a beautiful life. Let the millennia-old wisdom of jade continue to nourish our bodies and minds, guiding us towards a healthier and more beautiful future.

Jade, this gem condensed with the essence of heaven and earth, has played an indispensable role in the long history of Chinese medicine. It interprets the profound philosophy of "a benevolent physician, jade for health" in its unique way.
