Bo He (Menthae Haplocalycis Herba), commonly known as Field Mint, is a classical herb in Traditional Chinese Medicine known for its pungent, cooling nature and its actions on the Lung, Liver, and Gallbladder meridians. Widely used in Wind-Heat exterior syndromes, it helps clear Heat from the head and face, relieve headaches, soothe sore throat, open the nasal passages, promote sweating, and support natural fever reduction. Beyond respiratory benefits, Bo He also improves digestion by relaxing smooth muscles, reducing gastrointestinal spasms, relieving bloating, nausea, and supporting bile secretion. Modern studies highlight its antibacterial, antiviral, and antifungal properties. The herb also soothes Liver Qi stagnation, reduces stress, brightens the eyes, enhances mental clarity, and boosts alertness. Rich in menthol, its essential oil provides cooling analgesia, reduces neuropathic and muscular pain, and improves scalp microcirculation, supporting hair growth. Despite its many benefits, Bo He is contraindicated for individuals with Qi Deficiency, Yang Deficiency Cold (Xu Han), spontaneous sweating, hyperactive Liver Yang, and should not be used topically for infants due to the risk of respiratory suppression. This article presents a complete overview of Bo He's therapeutic actions, properties, chemical constituents, dosage, and safety considerations based on both TCM principles and modern research.
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.
