🌿 The Six Tastes (Ṣaḍ Rasa) in Ayurveda

Each food and herb has one or more of the six tastes, which affect digestion, the doshas (Vata, Pitta, Kapha), and the body’s tissues (dhatus). The six tastes are derived from combinations of the five great elements (Pancha Mahabhutas).

🌸 Role of Taste in Herbal Medicine

• Taste (Rasa) directly influences the therapeutic action of herbs.

• The tongue’s perception of taste sends signals throughout the body — influencing digestion, metabolism, and even emotional balance.

• Capsulated herbs lose part of their effectiveness because the tongue doesn’t perceive the rasa.

• Herbs are classified by:

  1. Primary taste (Rasa) – acts on plasma (rasa dhatu)

  2. Post-digestive taste (Vipaka) – acts on the nervous system

  3. Potency (Virya) – heating or cooling effect

📿 Example: Triphala contains all tastes except salty. It often tastes bitter at first (signifying need for that rasa), but as the body becomes balanced, it may taste sweet or sour later.
