👉 The nine fluids, also known as the humoral theory of health and disease, are blood, lymph, phlegm, black bile, yellow bile, blood plasma, mucus, sweat, and bile. These fluids are considered essential for maintaining the body's homeostasis and overall well-being. Each fluid has specific roles: blood transports oxygen, nutrients, and waste products; lymph aids in immune response and fluid balance; phlegm lubricates and protects mucous membranes; black bile is associated with digestion and detoxification; yellow bile aids in the digestion of fats; blood plasma carries nutrients, hormones, and waste products; mucus protects surfaces from pathogens; sweat regulates body temperature; and bile helps in the digestion of fats. Imbalances in these fluids can lead to various diseases, highlighting their crucial role in health.
