四气
sì qì本草理论
概述
Four Qi, also known as four natures, classify medicinal substances into cold, hot, warm, and cool properties based on their therapeutic effects on the body. These properties are derived from clinical observations of how substances alleviate or eliminate heat or cold patterns, guiding their use in Traditional Chinese Medicine.
理论要点
- The Four Qi (si qi) refer to the cold, hot, warm, and cool natures of medicinal substances, with a neutral nature (ping) for those whose effects are mild and not distinctly hot or cold.
- The property of a substance is summarized from its reactions and therapeutic effects in the human body: substances that reduce or eliminate heat patterns are considered cold or cool, such as Huangqin (Scutellaria) and Shigao (gypsum).
- Substances that reduce or eliminate cold patterns are considered warm or hot, such as Fuzi (Aconite) and Ganjiang (dried ginger).
- Cold and cool substances typically clear heat, purge fire, cool the blood, and resolve toxins; warm and hot substances typically warm the interior, disperse cold, support yang, and unblock meridians.
常见病机
- Disease patterns are characterized by heat or cold, and the Four Qi are used to counteract these imbalances.
- Heat patterns (e.g., fever, thirst, red tongue) require cold or cool substances to clear heat, while cold patterns (e.g., chills, cold limbs, pale tongue) require warm or hot substances to warm and dispel cold.
- Misuse of properties can exacerbate the condition, such as using hot substances for heat patterns or cold substances for cold patterns.
日常调养
- In daily life, one may choose foods and herbs with appropriate thermal nature according to one's constitution and seasonal changes, such as cooling foods in summer and warming foods in winter.
- Avoid excessive consumption of extremely cold or hot substances to maintain balance, especially for those with sensitive or weakened digestive systems.
