In the world of Traditional Chinese Medicine, Six Ingredient Rehmannia (Liu Wei Di Huang Wan) is a classic herbal blend revered for its ability to "nourish Yin", support kidney health, and promote overall vitality.  As one of the most widely used foundational formulas in Chinese Herbal Medicine, Six Ingredient Rehmannia has been trusted for centuries to bring balance to the body and support long-term wellness.

As one of our “Classic” formulas, we continue to be amazed by its relevance in today's crazy world.  But what exactly does it do, and why has it endured for generations? 

We take a deeper dive below.

The Essence of Six Ingredient Rehmannia From a Traditional Chinese Medicine Perspective

At its core, Six Ingredient Rehmannia is designed to replenish Kidney Yin, a fundamental concept in Traditional Chinese Medicine theory that relates to the body’s ability to maintain fluid balance, resilience, and deep nourishment.  

When Kidney Yin is depleted — often due to stress, aging, or overexertion — the body may experience dryness, restlessness, and a general sense of being “worn down.”

With the craziness of today’s society, where we’re constantly juggling responsibilities, dealing with screen fatigue, and pushing our limits, it’s easy for our Yin reserves to become depleted. This is where Six Ingredient Rehmannia comes into play.

“Six Ingredient Rehmannia is a cornerstone formula in Traditional Chinese Medicine because it provides deep nourishment for the body’s core.  By replenishing Kidney Yin, it supports hydration, resilience, and long-term well-being. It’s a formula that is timeless.”

 – Dr. Eric Karchmer, DAO Labs Chief Doctor of Traditional Chinese Medicine

From a Traditional Chinese Medicine perspective, this formula works to:

• Replenish Yin & Moisture: Helps counteract dryness, overheating, and depletion.

• Support Kidney & Adrenal Health: Aids in energy regulation and long-term vitality.

• Promote Inner Calm & Balance: Encourages a sense of grounding and restoration.
