👉 The seven fluids, or humors, traditionally identified in ancient medical theories, are now largely considered obsolete but historically significant. These fluids are blood, phlegm, yellow bile, black bile, lymph, mucus, and sweat. Each fluid is thought to correspond to specific bodily functions and emotions; for instance, blood is associated with vitality and warmth, while phlegm with stability and coldness. Yellow bile relates to digestion and heat, black bile to metabolism and melancholy, lymph to immunity and coldness, mucus to lubrication and dampness, and sweat to heat regulation and irritability. Though modern medicine has moved beyond this framework, these concepts have influenced holistic health practices and continue to be referenced in some alternative therapies.
