Heat-Clearing Medications: Helping Your Body Overcome Pathogenic Heat

I. Definition:

• Heat: Refers to the heat within the body. There are two types of heat:

• Physiologic heat: The heat generated by metabolic processes, providing the necessary warmth for bodily functions.

• Pathogenic heat: Also known as toxic heat, it’s the harmful heat that causes illness. Pathogenic heat can originate internally due to organ dysfunction or externally through exposure to pathogenic factors like wind, cold, heat, dampness, and dryness.

• Heat-clearing medications: These are herbal remedies designed to eliminate pathogenic heat from the body, restoring yin-yang balance and promoting recovery.

II. Symptoms of Pathogenic Heat:

• Common symptoms:

• Fever: Body temperature exceeding normal (above 37°C or 98.6°F).

• Dry mouth and thirst: Craving for cold drinks.

• Blood heat: Heat generated due to imbalanced organ function (liver fire, heart fire) or allergies, infections (itching, rashes, etc.); warm heat invading the blood, causing loss of fluids, neurotoxicity, vascular disturbances. This is often a complication of infectious diseases in their full-blown stages.
