When I first saw a TCM herbal formula, I was overwhelmed. Thirty ingredients in one prescription, each chosen for specific reasons. It seemed impossibly complex. Then I learned the basic categories, and suddenly it made sense.
TCM herbs are not random plants. They are organized into categories based on their properties, actions, and the organs they affect.
The Four Natures (Si Qi)
Herbs are classified by their temperature effect on the body:
- Hot (Re): Treats Cold conditions (ginger, cinnamon)
- Warm (Wen): Gently warms (dong quai, jujube)
- Neutral (Ping): Balanced (licorice, poria)
- Cool (Liang): Clears Heat (chrysanthemum, mint)
- Cold (Han): Strongly cools (coptis, dandelion)
The Five Flavors (Wu Wei)
Sour (Suan): Astringes and nourishes (schisandra, hawthorn)
Bitter (Ku): Clears Heat and dries Dampness (dandelion, scutellaria)
Sweet (Gan): Tonifies and harmonizes (ginseng, licorice)
Pungent (Xin): Moves Qi and Blood (ginger, mint)
Salty (Xian): Softens and moistens (seaweed, minerals)
The Four Main Herb Categories
