The efficacy of drinking water infused with Psoralea corylifolia (Bugu Zhi)
Psoralea corylifolia (Bakuchiol) steeped in water generally has functions such as nourishing kidney-yang, consolidating essence and reducing urine, warming the spleen to stop diarrhea, regulating qi to relieve asthma, promoting hair growth, and darkening hair.

1. Nourishing Kidney-Yang
Psoralea corylifolia can warm and nourish kidney-yang and is commonly used to treat various conditions caused by kidney-yang deficiency. Drinking Psoralea corylifolia-infused water warms and nourishes kidney-yang, alleviates pain, and improves symptoms such as cold intolerance, cold limbs, and frequent nocturia caused by kidney-yang deficiency. It helps enhance kidney function and improve the body's cold-deficient condition.
2. Consolidating Essence and Reducing Urination
Psoralea corylifolia has the effect of consolidating essence and reducing urine frequency. It can be used to treat symptoms such as seminal emission, spermatorrhea, enuresis, and frequent urination caused by kidney deficiency. Drinking Psoralea corylifolia-infused water appropriately can consolidate kidney essence, enhance the kidney's containment function, strengthen the control of seminal emission, reduce episodes of seminal leakage, and also help improve urinary incontinence.
3. Warming the Spleen and Stopping Diarrhea
Psoralea corylifolia warms spleen-yang and assists in treating diarrhea caused by deficiency of both spleen and kidney yang, especially diarrhea occurring at dawn (5 a.m. diarrhea). Drinking Psoralea corylifolia-infused water warms kidney-yang, thereby warming the spleen, enhancing the spleen's transformation and transportation functions, exerting effects of warming the spleen and stopping diarrhea, and alleviating diarrhea symptoms.
4. Regulating Qi and Relieving Asthma
Psoralea corylifolia acts on the kidney meridian. Since the kidney governs qi absorption, it helps the kidney regulate qi and relieve asthma, treating asthmatic wheezing caused by the kidney's failure to grasp qi. Drinking Psoralea corylifolia-infused water warms and nourishes kidney-yang, enhances the kidney's function of grasping qi, allows lung qi to descend properly, thus reducing asthma symptoms and alleviating breathing difficulties.
5. Promoting Hair Growth and Darkening Hair
The kidney-nourishing effect of Psoralea corylifolia indirectly benefits hair. It nourishes kidney essence, providing sufficient nutrition for hair growth, promoting hair growth, and improving problems such as hair loss and graying. It has a regulatory effect on premature graying and hair loss caused by kidney deficiency.
It is recommended to use Psoralea corylifolia-infused water under the guidance of a physician. Maintaining a light diet and healthy lifestyle in daily life will help sustain overall health.
