The Unani concept of Balgham (phlegm) occupies a central place in the understanding of Amrāḍ-i-Niẓām-i-Haḍm (digestive disorders), particularly where the Mizāj inclines towards Sard wa Ratab (cold–wet temperament). Classical authorities such as Jalīnūs, Ibn Sīnā (Al-Qānūn fī al-Ṭibb), and Zakariyyā al-Rāzī describe Balghamī maddah as a viscid, sluggish humor that, when produced in excess or altered in quality (mufriṭ or ghair-ṭabī‘ī), impairs the Quwwat-e-Hādima (digestive faculty), obstructs intestinal channels, and dulls gastric heat (harārat-e-ghareziya). This imbalance manifests in a spectrum of digestive ailments, from chronic indigestion and flatulence to gastritis, constipation-predominant syndromes, and sluggish bowel states. Unani therapeutics prescribes Khāṣṣ Balghamī Adwiya - drugs with specific phlegm-resolving actions-grounded in the principles of Ilājbil-Ḍidd (treatment by opposition), Tanqiya (evacuation), and Ta‘dīl-e-Mizāj (temperament correction). Classical formularies such as Makhzan al-Adviyah (Hakīm Najmul Ghani) and Bayaz-e-Kabir detail the use of Muḥallil (resolvent), Muṣaffī (purifier), Mulaṭṭif (attenuant), and Muharrik-e-Harārat (stimulant of gastric heat) drugs-examples include Zanjabeel (Zingiber officinale), Filfil Siyah (Piper nigrum), Saqrub, and Arq-e-Awāmis. This review synthesizes classical doctrines with contemporary biomedical research (2010–2025) that has begun to validate the pharmacological profiles of these drugs-demonstrating actions such as prokinetic effects, mucolysis, antioxidant defense, and modulation of gastric secretions. The paper explores how Unani descriptions of viscous cold phlegm parallel modern notions of mucus hyperviscosity, delayed gastric emptying, and low-grade mucosal inflammation, thereby providing a conceptual bridge between humoral theory and modern gastroenterology. By integrating literary exegesis of canonical Unani texts with critical appraisal of recent experimental and clinical evidence, this revi
