The Efficacy, Functions, and Contraindications of Psoralea corylifolia

Psoralea corylifolia is a traditional Chinese medicinal herb that offers various therapeutic effects and benefits, but it also has certain contraindications. It can tonify the kidney and strengthen yang, effectively improving symptoms such as kidney deficiency-induced impotence, cold pain in the lower back and knees. This herb has the effect of consolidating essence and reducing urinary frequency, providing therapeutic benefits for conditions like seminal emission, enuresis, and frequent urination due to kidney deficiency. Psoralea corylifolia can warm the spleen and stop diarrhea, helping alleviate symptoms associated with spleen and kidney yang deficiency, such as early-morning diarrhea (wugengxie). It also supports kidney function, enhances yang energy, anchors qi, and relieves asthma, thus improving conditions like failure of the kidney to anchor qi and asthmatic cough due to deficiency-cold. Additionally, Psoralea corylifolia may help prevent heart failure, promote hemostasis, protect the cardiovascular and cerebrovascular systems, and exert antibacterial effects. However, it may cause allergic reactions; individuals sensitive to its components should avoid using it. As a warming herb, Psoralea corylifolia is contraindicated in individuals with yin deficiency and excessive internal heat, as it may exacerbate their symptoms. It may also worsen constipation, so individuals suffering from constipation should avoid its use. When using Psoralea corylifolia, it is essential to strictly follow medical advice to avoid unnecessary risks.
