Nature: acrid, hot

Also used for other conditions where the upper part of the body is hot (e.g. dry mouth, sore throat, or toothache that become worse at night) and the lower part is cold (e.g. lower back pain, cold lower extremities, diarrhea, weakness in the proximal position of the pulse). To conduct floating Yang back to the kidneys, a tiny dose is used – 0.1 to 0.5g.

DY: Supplements the source Qi.
• By supplementing source Qi, it assists in the engenderment of Qi, blood, and essence (as in Shi Quan Da Bu Wan [Ba Zhen Tang + Huang qi and Rou gui]).
• Real Rou gui is very expensive. Many importers sell the culinary quality – Gui pi – which has little medicinal value. It focuses on the middle burner. It does not reinforce kidney Yang or Ming Men fire.
• With Huang lian (3-6g each) to harmonize Yin and Yang, drain the south (heart fire) and supplement the north (kidney Yang), and re-establish the interaction between the heart and kidneys. For indications such as:
– 1. Insomnia, vexation, and agitation due to heart and kidneys not communicating. (Such as for kidney Yang deficiency which cannot move and upbear kidney water, which then becomes dead and stagnant, and fails to nourish heart Yin and control heart fire which rises upward. Use Jiao Tai Wan.)
• As a powder (Rou gui mo or Rou gui mian), some expense can be spared, as it needs only be prescribed at a dose of 1-2g daily, taken directly or added to a decoction within the last 5 minutes of cooking.
Dose: 1.5-4.5g (to conduct floating Yang back to the kidneys, use 0.1-0.5g)

 

Guan Gui: the thinner bark of trees that are 6-7 years old

Dose: 4.5-9g
Rou Gui Xin (Gui Xin): the heart of Rou gui
• This is cinnamon bark which has been cleaned of its fine, superficial layer.
