The Efficacy and Functions of Salt-Processed Psoralea corylifolia

Psoralea corylifolia (Salt-processed) has good effects in tonifying kidney and reinforcing yang, as well as warming and strengthening the spleen and stomach. Clinically, it is commonly used not only for treating various conditions caused by kidney deficiency, such as diarrhea due to deficient cold in the kidney, enuresis, impotence, or nocturnal emission, but also for treating symptoms like diarrhea, abdominal distension, aversion to cold with cold limbs, and predawn diarrhea caused by yang deficiency of both spleen and kidney. It is suitable for patients with insufficient kidney yang or deficient spleen yang. However, it should not be used in cases of yin deficiency with hyperactive fire or constipation due to heat accumulation.
