Begin Your Destiny™
This is Si Jin Bao’s version of a classical formula that dates back to the 17th century. It is well known for addressing symptoms of insufficiency of the Kidney-Yang and decline of fire from Ming Men as well as Wei Syndrome (Atrophy disorder) due to Kidney Qi and Yang Deficiency .
Rekindle the Fire at the Root
Yòu Guī Tāng, the Restore the Right (Kidney) Decoction, is Si Jin Bao’s version of Zhang Jing-yue’s classical formula for a Kidney Yang grown cold. It warms and rebuilds the fire of the right Kidney, the Ming Men, and replenishes the Essence that fire depends on.
The right Kidney holds the Ming Men, the gate of vitality, the warm fire at the body’s root. When that fire declines, cold rises from within. The lower back and knees ache and weaken, the limbs never quite warm, desire and fertility fade, and the stools loosen before dawn. This formula was built to rekindle it.
Seek the Yang within the Yin
The formula appears in the Jǐng-Yuè Quán Shū (Collected Treatises of Zhang Jing-Yue), completed in 1624. Zhang Jing-yue built a matched pair, Yòu Guī for the right Kidney and its Yang, Zuǒ Guī for the left and its Yin, on a rule he stated plainly: to tonify the Yang well, one must seek it within the Yin. So he warmed the Kidney with Aconite and Cinnamon, then set that fire in a bed of rich Yin and Blood tonics, so the warmth would have something to hold to.
The classical rendering included deer-antler gelatin, an animal tonic of the Yang and Essence. Si Jin Bao prepares the formula vegan, without that ingredient, leaning on warming Aconite and Cinnamon and on the seeds and roots that replenish the Essence: Dù Zhòng, Tù Sī Zǐ, and Shú Dì Huáng.
Kidney Yang Deficiency · 腎陽虛
The pattern is a decline of the Kidney Yang and the Ming Men fire. It shows as cold that comes from within: aversion to cold and cool limbs, aching and weakness of the lower back and knees, impotence or infertility, loose stools or dawn diarrhea, and at times a swelling of the legs as the Yang fails to move the water.
- Aversion to cold and coolness of the extremities
- Aching and weakness of the lower back and knees
- Impotence, infertility, spermatorrhea
- Loose stools; edema of the lower legs; lumbar and limb pain
Classical tongue & pulse: a pale, swollen tongue with a white coating; a deep, weak, and slow pulse.
Warm the Fire, and Feed It
Zhì Fù Zǐ and Ròu Guì bring the warmth, rekindling the Ming Men fire and driving out the deep cold. Warmth alone would only scatter, so Shú Dì Huáng, Shān Zhū Yú, Gǒu Qǐ Zǐ, and Dāng Guī fill the Yin and Blood that give the fire a place to settle.
Dù Zhòng and Tù Sī Zǐ strengthen the lower back and secure the Essence, and Shān Yào anchors the whole in the Spleen and Kidney. Warm the fire, and feed it, and the Yang returns without burning itself out.

Yòu Guī Tāng
When the fire at the body’s core burns low, the cold comes from within: the back and knees ache and give way, the limbs never quite warm, desire and fertility fade, the stools loosen before dawn. Zhang Jing-yue set out to rebuild that fire, but not with heat alone. He held to a rule of his own, that to tonify the Yang well one must seek it within the Yin, and so he warmed the Kidney with Aconite and Cinnamon while feeding it with rich Rehmannia and the seeds and fruits that replenish the Essence. Below is each herb on its own terms: its nature, the channels it enters, its classical actions, and the part it plays here.

A Kidney Yang that has run cold is felt in the low back and the knees, in limbs that will not warm and a vitality that has dimmed. Yòu Guī Tāng rebuilds that fire, and while the effect belongs to the whole formula, each of its nine herbs has also drawn modern study on its own. What follows is that record, taken herb by herb.
Each herb has been examined on its own, and the pattern of the findings mirrors the pattern of the formula: two herbs that warm, and a company of seeds, barks, and roots that fill and secure. Four centuries on, the mechanisms now carry names for the rule Zhang Jing-yue set down: to tonify the Yang well, seek it within the Yin.
