Liuwei Dihuang Wan, also known as Six Flavor Rehmanni or Rokumi-gan in Japanese Kampo, is a well-known traditional Chinese medicine (TCM) prescription with a rich history dating back over a thousand years. This herbal formula is renowned for its ability to address yin deficiency, a common concept in TCM, and is widely used in eastern Asia.

Historical Origins

The formula for Liuwei Dihuang Wan was originally created by Qian Yi and published in the book “Xiao’er Yao Zheng Zhi Jue” in 1119.

Over time, it has undergone slight modifications, especially when it was adopted into Japanese Kampo medicine. Some Chinese herbs were replaced with their Japanese counterparts to adapt the formula to the region’s resources.

Key Ingredients

Liuwei Dihuang Wan is a complex blend of six herbal ingredients, each with its own unique properties and functions:

1. Rehmanniae Radix (Chinese Foxglove Root): Nourishes kidney yin and essence.
2. Corni Fructus (Japanese Cornel Fruit): Nourishes the liver and kidney, restraining the leakage of essence.
3. Dioscoreae Rhizoma (Chinese Yam Rhizome): Tonifies spleen yin and consolidates essence.
4. Alismatis Rhizoma (Water Plantain Rhizome): Promotes urination to prevent the buildup of significant fluids.
5. Poria (Tuckahoe Mushroom): Drains dampness from the spleen.
6. Cortex Moutan Radicis (Tree Peony Bark): Clears liver fire.

These ingredients work synergistically to address yin deficiency and related health issues.
