In the relationship between the production and grams of the five internal organs, the spleen has an inhibitory effect on the kidney, which belongs to water and the spleen belongs to soil. Therefore, there is a saying that kidney disease is caused by the spleen, and there are also anti-grams, so I will not discuss it in detail.
The restraint of spleen on kidney is not a restriction on its normal function, but on its abnormal performance. Only when kidney disease is rampant, the spleen will restrict the kidney. I understand it this way. Is it accurate?
