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.
Dendrobium Stem (Dendrobium nobile Lindl., Dendrobii Caulis) is one of the most valued tonic herbs in Traditional Chinese Medicine (TCM), renowned as “Golden Stem Dendrobium” – a superior Yin-nourishing and life-prolonging herb. With its sweet flavor and slightly cold nature, it enters the Lung and Kidney meridians, replenishing Yin fluids, clearing internal heat, tonifying the Stomach, moistening the Lungs, brightening the eyes, strengthening tendons, and enhancing overall vitality. Traditionally, it is used to treat Yin deficiency syndromes such as dry mouth, thirst, low-grade fever, night sweating, internal heat in the bones, post-illness fatigue, impotence, cystitis, blurred vision, dizziness, periodontal inflammation, and dry skin. Chemically, Dendrobium nobile contains valuable bioactive compounds including dendrobine (its main sesquiterpene alkaloid), nobiline, polysaccharides, bibenzyls, phenanthrenes, flavonoids, vitamins, and essential minerals. These substances contribute to its antioxidant, immune-regulating, Yin-restoring, and tissue-rejuvenating effects. The herb is usually prepared by decoction, gentle steaming, or extracted into tonic formulas, with a typical daily dose of 6–15 g dried material. Revered for centuries as a “longevity herb,” Dendrobium Stem nourishes the body, revitalizes energy, enhances skin hydration, and promotes graceful aging — just as ancient physicians said: “Regular use of Shi Hu brings youth to the face and life as enduring as the pine.”
