Role of Impaired Digestion in Disease Pathogenesis: According to Unani System of Medicine
Abstract: The relationship between digestion and disease occupies a central position in Greco-Arab (Unani) medicine, as emphasized by classical physicians such as Ibn Sina and Al-Razi. In Unani medicine, digestion (Haḍm) is not confined to the gastrointestinal tract alone but represents a comprehensive physiological and metabolic process involving four sequential stages: gastric digestion (Haḍm-e-Mi‘dī), hepatic digestion (Haḍm-e-Kabidī), vascular digestion (Haḍm-e-‘Urūqī), and tissue digestion (Haḍm-e-‘Uḍwī). These stages are governed by Quwwat-e-Hāḍima (digestive …

Long-Term Effects of Feeding High-Lignin Forage to Ruminants: Implications for Productivity, Health, and Sustainability
Abstract: The long-term feeding of high-lignin forage to ruminants can significantly impact various aspects of animal performance, health, and environmental sustainability. Lignin, a complex phenolic compound present in plant cell walls, is indigestible by rumen microbes, leading to reduced fiber digestibility and decreased nutrient utilization. Over time, feeding ruminants with forages high in lignin results in a decline in voluntary dry matter intake (DMI), inefficient energy and protein absorption, and suboptimal …
