Introduction
In general, the main functions and effects of Psoralea corylifolia (Bakuchiol) include nourishing the kidneys and invigorating yang, warming the middle jiao to strengthen the spleen, consolidating essence and reducing urination, regulating qi to relieve asthma, and promoting bone health. It is commonly used to alleviate symptoms such as kidney yang deficiency, coldness due to spleen and stomach weakness, frequent and excessive urination, and shortness of breath with wheezing. However, it should be consumed in moderation to avoid increasing the burden on the gastrointestinal tract. Additionally, special populations should take it under medical supervision.

Psoralea corylifolia (Bakuchiol) is a common traditional Chinese medicinal herb. Its main functions and benefits generally include nourishing the kidneys and strengthening yang, warming the middle jiao to invigorate the spleen, consolidating essence and reducing urine frequency, promoting the downward reception of qi to relieve asthma, and supporting bone health. Specific details are as follows:

1. Nourishing the Kidneys and Strengthening Yang

Certain substances in Psoralea corylifolia help maintain kidney health, thereby achieving the effect of strengthening kidney function and yang energy, such as coumarin compounds and flavonoid compounds. It can be used to alleviate symptoms such as soreness and weakness in the waist and knees, seminal emission, cold intolerance in the limbs, and physical fatigue.

2. Warming the Middle Jiao and Invigorating the Spleen

Psoralea corylifolia is warm in nature and has the effect of warming the middle jiao and dispersing cold, which can relieve discomfort caused by spleen and stomach deficiency-cold, such as diarrhea, abdominal pain, nausea, vomiting, and poor appetite.

3. Consolidating Essence and Reducing Urine Frequency

Psoralea corylifolia also has the effect of consolidating essence and reducing urine frequency. It can contract the urethral sphincter muscles and increase tension at the bladder neck, alleviating symptoms such as frequent urination, excessive urination, and incomplete voiding. It is suitable for individuals experiencing nocturnal polyuria.

4. Promoting the Downward Reception of Qi to Relieve Asthma

Psoralea corylifolia has the function of strengthening kidney yang and promoting the downward reception of qi to relieve asthma. It is suitable for patients with deficiency of both the lungs and kidneys and can help alleviate symptoms such as wheezing and shortness of breath.

5. Supporting Bone Health

Components of Psoralea corylifolia can promote the absorption of calcium and phosphorus, increase bone density, support bone growth and development, maintain bone health, and accelerate the healing of fractured bone ends. It is suitable for individuals with osteoporosis or fractures.

Although Psoralea corylifolia offers many benefits, attention should be paid to the dosage to avoid discomfort caused by excessive consumption. Additionally, pregnant women, lactating women, children, and individuals with yin deficiency and excessive internal heat should take it only under medical supervision.
