Bu Gu Zhi (Cullen corylifolium (L.) Medik., syn. Psoralea corylifolia L.), commonly known as Babchi or Bakuchi seed, is a traditional Chinese medicinal herb renowned for its Kidney-Yang tonifying, Spleen-warming, and essence-preserving effects. The dried seeds, with a bitter-acrid taste and warm nature, enter the Kidney, Spleen, and Pericardium meridians. In Traditional East Asian Medicine, it is prescribed for impotence, spermatorrhea, frequent urination, chronic diarrhea, lumbar weakness, vitiligo, psoriasis, and general deficiency or aging syndromes. Modern pharmacological studies have identified key bioactive compounds—bakuchiol, psoralen, isopsoralen, isobavachalcone, and various flavonoids and terpenes—responsible for its anti-inflammatory, antioxidant, osteogenic, immunomodulatory, and skin-rejuvenating properties. Bakuchiol, in particular, is widely used in dermatology and cosmetics as a natural alternative to retinol. Clinical and laboratory evidence also supports Bu Gu Zhi’s potential in improving bone metabolism, cardiovascular function, hormone balance, and anti-tumor activity. With its dual legacy of ancient wisdom and modern validation, Bu Gu Zhi stands as a bridge between traditional Oriental medicine and contemporary integrative health science. Proper dosage and caution are advised, as the herb should be avoided in patients with Yin deficiency with heat, urinary tract inflammation, or constipation.
Licorice Root (甘草, Gān Cǎo) – Glycyrrhizae Radix et Rhizoma – refers to the root and rhizome of Glycyrrhiza uralensis, G. glabra, or G. inflata from the Fabaceae family. In Traditional Chinese Medicine, Licorice is honored as the “National Elder”, the harmonizing herb that balances hot and cold properties of other medicinals. Sweet in taste and neutral in nature, it enters the Spleen, Stomach, Heart, Liver, and Lung meridians, promoting Qi replenishment, detoxification, cough relief, and internal balance. Modern pharmacological studies reveal that compounds such as glycyrrhizin, glabridin, and liquiritin possess anti-inflammatory, antimicrobial, hepatoprotective, immunoregulatory, and antioxidant activities. Licorice Root is widely used in formulas for treating coughs, sore throat, gastritis, fatigue, endocrine imbalance, and skin disorders. However, excessive or prolonged use may cause hypertension and hypokalemia due to mineralocorticoid-like effects. As both a medicine and a harmonizing agent, Gān Cǎo remains an indispensable herb bridging the wisdom of traditional healing and modern therapeutic science.
