I know I could run the risk of repeating myself so please bear with me. If I am correct there are 2 real problems that could cause mental problems. Heart fire. Or some kind of rising heat. Or phelgm in the heart. Phelgm is dampness or water that has been acted upon and heated. I guess by chi. So it’s a “damp heat”. Dampness turning by heat. So would you want to get rid of the heart fire and get rid of the phelgmatic problem? By draining or such. I have heard that phelgm is the second worst problem second to “floating yang”.
