Steamed Glutinous Rehmannia (Shudihuang)

The Ancient Chinese Secret to Wellness and Longevity

Chinese traditional medicine has a rich history of using natural remedies to promote health and longevity. One of the most revered herbs in this tradition is glutinous rehmannia, commonly known as Shudihuang. This article delves into the history, processing, and medicinal uses of Shudihuang, highlighting its significance in Chinese herbalism and its potential benefits for modern-day health.

The Tale of Mayor Lin and the Legendary Herb

In ancient China, Mayor Lin, a government official during the Ming Dynasty (1368-1644), was said to have fathered a child at the remarkable age of 104. This extraordinary feat was attributed to his regular consumption of glutinous rehmannia, an herb known for its rejuvenating properties. Today, this herb continues to hold a prominent place in Chinese medicine, with its unique processing method and versatile applications in various health conditions.

Shudihuang: A Tale of Two Forms

The processing of glutinous rehmannia is an intricate and labor-intensive process, involving ten cycles of steaming and nine cycles of drying under the sun. The result is a shiny, black herb known as Shudihuang, or "old place." This contrasts with the raw form of the herb, which is referred to as "new place." These distinct forms have unique medicinal properties, making them suitable for different health conditions.

Raw glutinous rehmannia is known to reduce heat in the blood, whereas the processed form, Shudihuang, is effective in treating blood deficiency. As a result, these two forms are classified as separate herbs in Chinese herbalism, with distinct clinical applications.

Modern Research and Clinical Applications

Recent studies have corroborated the ancient wisdom surrounding Shudihuang, demonstrating its efficacy in treating various health conditions. For instance, the Chinese Medical Journal has reported its effectiveness in managing rheumatic and rheumatoid arthritis. Additionally, when combined with licorice, glutinous rehmannia has shown promise in treating bronchial asthma and contagious hepatitis.

Shudihuang: A Treasure Trove of Healing Properties

Belonging to the Scrophulariaceae family, Shudihuang (scientifically known as Rehmannia glutinosa Libosch) is a powerful herb that boasts a range of medicinal properties. It is primarily used to tone blood, nourish yin, support kidney function, and even reverse the graying of hair. It has been traditionally prescribed for a variety of ailments, including blood deficiency, tinnitus, night sweats, vaginal bleeding, diabetes, and seminal emission.

Moreover, scientific research has demonstrated Shudihuang's ability to protect the liver and reduce blood sugar levels, making it a valuable herb for modern-day health concerns.


Shudihuang, the ancient Chinese herb revered for its remarkable health benefits, continues to capture the interest of both traditional and modern medicine. Its unique processing methods and versatile applications in treating various ailments make it an indispensable treasure in the world of natural remedies. With ongoing research and growing interest in its potential benefits, Shudihuang is set to remain a vital component of health and wellness for generations to come.
