Main Combinations:
1. Blood deficiency and Menstrual disorders associated with Blood deficiency, with Dang Gui, Paeonia Bai Shao, Ligusticum Chuan Xiong (as in Si Wu Tang)
2. To strengthen the Kidneys and Nourish the Yin or Yang, combine with Cornus Shan Zhu Yu and Dioscorea Shan Yao. This trio forms the basis of the most important formulas used to strengthen the Kidneys. Alone, they nourish Kidney Yin and are usually corrected with the addition of Poria Fu Ling, Alisma Ze Xie and Paeonia Mu Dan Pi (as in Liu Wei Di Huang Wan, 'Rehmannia 6'). When combined with Cinnamon (Rou Gui) and Aconitum Fu Zi, it is called Shen Qi Wan (Kidney Qi Pill) and is used for Yang deficiency.
3. To strengthen Kidney Yang, add Cinnamon and prepared Aconitum Fu Zi.
4. Heat with Yin deficiency, combine with Gui Ban (Turtle shell), Phellodendron Huang Bai and Anemarrhena Zhi Mu.
5. To more strongly nourish Yin and clear Heat, strengthen the bones an calm the Mind and Nerves, combine with Pearl.
6. To avoid the heavy, cloying, hard-to-digest nature of Rehmannia from overwhelming the Spleen, Costus or Amomum Sha Ren can be added.
