1. First of all, we should identify the nature of the lesion. Which of the eight levels of identification are involved? I feel that Yin, Cold, Deficiency, Actual, Internal and Superficial should be the main ones, among which “Deficiency” naturally needs no explanation – Yang deficiency cold; although the swelling of the lower limbs can be considered “on the surface”, it is the external manifestation of Cold-Dampness in the Internal Although the swelling of the lower extremities can be considered “on the surface”, it is an external manifestation of cold and dampness in the interior. 2, followed by what pathological factors are involved? Chinese medicine treatment, there is no other than “help righteousness” or (and) “remove evil”. But the so-called dispel evil, is only for the common wind, cold, summer, dampness, dryness, fire, heat, phlegm, stagnation, toxicity, depression, which is only a limited number of evil, so look at this patient what “evil”? Cold, dampness and water are the obvious evidence, but is there phlegm or stasis? Is there qi stagnation? Astringency in the mouth is mostly due to dryness and heat that injures the fluids, and salivation is more due to spleen deficiency or kidney deficiency, such as non-transportation or water flooding. 3. Thirdly, where is the disease? You said in the middle jiao, it seems that not only that, it is more practical to identify the location of the disease from the five organs to analyze. I see more in the spleen and kidney, in the spleen for good reasons, in the kidney based on the lower extremities swelling, morning stool urgency, Zhongjing so-called swelling below the waist when the urine to choose kidney qi pill, morning diarrhea has similar to the five night discharge – more spleen and kidney deficiency cold, or even kidney deficiency. Many other aspects can be judged not only in the spleen, but also in the kidneys. You can carefully speculate in many aspects. In addition, why can astringent mouth and saliva be seen together? Generally, when there is not much fluid in the mouth, the mouth will be astringent, and as it is said in the book, astringency in the mouth is mostly due to dryness and heat that injures fluid, but in this patient, both are seen at the same time. In addition, the feeling of “wood” in the limbs, we should consider the problem of qi and blood, “qi deficiency is numb, blood deficiency is wood”, this patient’s wood, blood deficiency? Or is it due to Yang deficiency cold and dampness. 4, analysis so far, the direction of treatment will not be a big mistake. You preferred Ling Gui Zhu Gan Tang with Job’s Tears, the urgency of the stool disappeared in the morning after the medicine, the amount of food increased, dry mouth, etc., showing that the drug has the right symptoms, the second diagnosis you used the formula is obviously too disorganized. For example, is the addition of white peony with Gui Zhi to regulate the Ying and Wei, or is it combined with Radix et Rhizoma Polygonati, or do you want to complement the warm medicine? And add maidenhair, raw earth a little, all seem indecisive, or trying to be all things to all people? My experience is that yin evidence with yin and soft products unless in parallel with the masculine medicine can be. In conclusion, this patient, naturally, has been ill for a long time, and deficiency and reality coexist, so treatment does not need to be rushed. The basic and main contradictions can be solved to obtain remarkable results. In the treatment, you can “cross the river by feeling the stones” and adjust the direction and priority while treating. The next time you prescribe, I think there are several ways to consider, focusing on warming Yang, drying dampness, strengthening the spleen and benefiting the kidneys, along with invigorating the blood and clearing the channels. For example, you can gradually and boldly increase the dosage of Radix et Rhizoma – but first decoction – gradually increasing, or available up to 30~50g, of course with dry ginger, licorice, cinnamon stick, etc. If the limbs are edematous, Huang Qi He, Fang Qi and Gui Zhi can be considered, because Huang Qi is a medicine that goes to the surface, combined with Radix Aconiti, you can try. These years, the Chinese medical community is very prosperous Fu Yang school, I support that there is a reason for it, but I think we can not go too far, but to “have is the evidence with is the medicine”, and with the evidence of the combination can be.
