Settle the Yang (Chai Hu Jia Long Gu Mu Li Tang) has at its core Harmonize the Qi (Xiao Chai Hu Tang), which has a balanced effect on normalizing the movement of Yang energy in and out of the body core. It is used to restore circulation within the Triple Burner, and the movement back and forth of Yang energy by the Shao Yang layer of the body. Harmonize the Qi also directly supplements Qi that has been damaged from prolonged or severe Yin Yang separation.

In Settle the Yang, herbs have been added that bring the focus of the formula strictly on Yang internalization. A failure of Yang energy to internalize properly, or to move outwards too exuberantly, seems more common in the spring and fall months. Stratification occurs, with Yang being trapped in the outer layers of the body and Yin consolidated in the interior.

These herbs give the formula a more one-sided Yang internalizing effect. The heavy mineral elements of Dragon bone and Oyster shell sink Yang energy into the interior without depleting it. Chinese rhubarb rhizome and root purges Fire downwards and inwards, while relieving agitation and anxiety. Poria is calming, and teams with Chinese cinnamon twig to mobilize fluids in the body and support normal urine production. Chinese cinnamon twig also helps expel any internalized Cold invasion back outwards through the Tai Yang layer.
