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, beyond its aesthetic and ceremonial value, jade has also played an indispensable role in the Chinese philosophy of health preservation. Especially in Li Shizhen's monumental work, "Bencao Gangmu" (Compendium of Materia Medica), jade was endowed with unique medicinal properties, revealing the ancients' profound understanding of nature's gifts and their persistent pursuit of health and longevity.

The story begins in the distant prehistoric era. In the Neolithic Liangzhu culture sites, a large number of exquisite jade artifacts were unearthed, including jade bi discs and cong tubes, which were not only mediums for worshipping heaven and earth but also carried the early people's simple cognition of cosmic order and the cycle of life. At that time, people might have vaguely perceived a certain special energy in jade, regarding it as a sacred object for communicating with deities, warding off evil, and curing diseases. This primitive belief laid the cultural foundation for the later use of jade in medicine.

By the Spring and Autumn and Warring States periods, as various schools of thought contended, medical ideas gradually emerged. The "Shan Hai Jing" (Classic of Mountains and Seas) records the saying "wearing jade to ward off evil," while the "Shennong Bencao Jing" (Shennong's Materia Medica) even listed jade as a superior-grade herb, stating that "long-term consumption lightens the body, prolongs life, and makes one immortal." These early medical records, though imbued with a strong mystical color, reflect the ancients' preliminary exploration of jade's medicinal value. They observed jade's warmth, toughness, and luster, and linked them to the human body's vital essence, believing that jade could harmonize yin and yang and nourish the internal organs.

It was Li Shizhen's "Bencao Gangmu" in the Ming Dynasty that truly systematized and theorized the medicinal value of jade. In this comprehensive medical masterpiece, Li Shizhen meticulously documented various medicinal effects of jade. He categorized jade into "jade dust" and "jade powder," believing that it tasted sweet, was neutral in nature, and non-toxic, possessing functions such as "removing heat from the stomach, relieving shortness of breath and vexation, quenching thirst, moistening the heart and lungs, aiding the voice and throat, nourishing hair, calming the soul, benefiting blood circulation, and brightening the eyes and ears." The book also recorded methods for treating various diseases with jade, such as applying jade dust to the face to moisturize the skin, and taking powdered jade internally to clear heat, detoxify, and calm the nerves. These records were not groundless but were compiled by Li Shizhen based on extensive collection of folk remedies, consultation of ancient texts, and his own practical experience.

So, why did the ancients believe that jade possessed such miraculous healing properties? This is rooted in profound traditional Chinese medicine theory. TCM emphasizes "the unity of heaven and man," believing that the human body is intimately connected with nature. As a product of nature, jade has undergone billions of years of geological changes, containing the essence of heaven and earth. The ancients believed that the trace elements and minerals in jade, such as calcium, magnesium, zinc, and selenium, could be absorbed by the human body through skin contact or internal consumption, thereby playing a role in health preservation and treatment. Furthermore, jade's physical properties, such as its warm and smooth touch and stable temperature, were also believed to have a positive impact on the human body. For example, wearing a jade bracelet can massage acupuncture points on the wrist, promoting blood circulation.

Modern science has also explored the medicinal value of jade. Although not all the effects mentioned in "Bencao Gangmu" have been fully confirmed, research indicates that certain types of jade do contain trace elements beneficial to the human body, and their unique physical structure may possess certain biological activity. For instance, some scientists believe that negative ions generated by jade during friction may be beneficial to human health. In addition, the warm and cool touch of jade, to a certain extent, also has a role in physical therapy, such as jade pillows and jade massagers, which are widely used to relieve fatigue and improve sleep.

To this day, the health-preserving culture of jade continues to thrive across China. From wearing jade ornaments for peace and health to using jade massage tools to soothe the body and mind, jade has long been integrated into our daily lives. It is not merely a beautiful stone but also the crystallization of the Chinese nation's millennia-old health wisdom, carrying the ancients' reverence and exploration of life, health, and nature. When we touch a piece of warm jade, it feels as if we can travel through time, experiencing the love for life and the quest for natural mysteries found in "Bencao Gangmu." This is precisely the eternal charm of jade culture.
