Deeply nourishing, even Rehmannia's roots grow deep.
Deeply nourishing, even Rehmannia’s roots grow deep.

This is the original Jin Gui (aka Ba Wei) with Fu Zi. If you are uncomfortable with this then you can order a Fu-Zi-Less version here. Jin Gui Shen Qi Wan w/o Fu Zi. 

This extraordinary formula does it all. Three herbs to urinate out edema, three herbs to prevent frequent urination, and two herbs to warm the underlying deficiency and three herbs to prevent frequent urination.

This formula’s original name translates to the “Kidney qi pill” which is to say that it normalizes the functions of the Kidneys and their many functions. Whether you’re peeing too much or not enough, the Kidney qi pill will get you going in the right direction and more importantly in the right amount.

Of course, in Chinese medicine, “Kidney qi” or functions are not limited solely to regulating urination. Kidney qi is what tends to become deficient as we age (according to Chinese medical knowledge). As such, this formula can help to regulate the quality of your hearing, low back pain that is aggravated by fatigue, knee weakness or pain, bone density, and libido. These are all reliant on the health of the Kidneys, and the Kidney qi pill is the core herbal approach to these issues.

Fu Zi 附子 This Version of the Formula contains Fu Zi  Radix Lateralis Aconiti Carmichaeli Praeparata [don’t use if pregnant]

Rou Gui 肉桂 inner bark of Saigon cinnamon, cinnamon bark Cinnamomi Cortex [don’t use if pregnant– or without advise of a professional herbalist]

      • These two herbs are warming and spicy. They’re the fire that burns, like the spark in your car’s engine that ignites the fuel, giving rise to the qi power of this formula. Plus rou gui (cinnamon bark) tastes good. So there’s that too. :)

Shu Di Huang 生地黃 Chinese foxglove root, rehmannia (prep),Rehmannia root Radix Rehmanniae Glutinosae

Shan Yao 山藥 dioscorea rhizome, Chinese yam Dioscoreae Rhizoma

Shan Zhu Yu 山茱萸 Asiatic cornelian cherry fruit, cornus Corni Fructus

      • These three herbs all help the body produce more fluids. This fluid is the fuel that is burned by the two warming herbs above. Sheng Di Huang is a very deep root that nourishes the body fluids deeply (picture above). Shan yao (a yam) and shan zhu yu (a sour cherry) round out the moistening and nourishing herbs in this formula. Because of shan zhu yu’s sour nature, it helps suck in excessive urination to address frequent urination or dribbling after you’re done.

Mu Dan Pi 牡丹皮 moutan root bark, tree peony root bark Cortex Moutan Radicis

Fu Ling 茯苓 sclerotium of tuckahoe, China root, hoelen, Indian bread Poria Cocos

Ze Xie 澤瀉 alisma rhizome, water plantain Rhizoma Alismatis Orientalis [supports pregnancy]

      • Mu dan pi is teamed up with the two diuretics fu ling and ze xie in order to stimulate blood flow in the urogenital system. This regulates one of the key Kidney functions, which is water metabolism. Folks who seek out the benefits from this formula often do so in order to regulate their urinary output.
