Licorice — Yashtimadhu in Sanskrit — is one of the most important and most widely used herbs in the entire Ayurvedic pharmacopoeia, celebrated for its exceptional sweet taste, its cooling and soothing properties and its remarkable breadth of therapeutic application across the respiratory, digestive, reproductive and nervous systems. Its Sanskrit name Yashtimadhu is both precise and evocative: yashti means stick or rod referring to the straight rod-like dried root and madhu means honey or sweet — together perfectly describing the character of this herb as the sweet honey-like root. It is the sweetest natural substance in the plant kingdom — its primary active compound glycyrrhizin is approximately fifty times sweeter than sucrose.
In Ayurvedic pharmacology licorice is classified as Rasayana, Balya, Medhya, Chakshushya (beneficial for eyes), Keshya (beneficial for hair), Kasahara (relieves cough) and Shwasahara (relieves dyspnoea). What makes licorice clinically distinctive is its combination of digestive properties with a cooling potency — making it one of the primary Pitta-pacifying herbs in the classical system. The respiratory system is its most important clinical domain in modern practice — licorice is the central herb in classical Ayurvedic treatment of cough, bronchitis, sore throat, laryngitis and chronic inflammatory respiratory conditions.
Modern research has confirmed glycyrrhizin and glycyrrhizinic acid as primary active compounds with significant anti-inflammatory and immunomodulatory effects. Studies demonstrate gastroprotective activity in peptic ulcer conditions. Clinical research confirms adrenal-supporting cortisol-modulating effects. Antiviral properties have been demonstrated against multiple viruses. The most important safety consideration is avoiding prolonged high-dose use which can cause pseudoaldosteronism with sodium retention and hypertension. DGL (deglycyrrhizinated licorice) is a safer option for long-term digestive use.
