Ayurveda: Dosha Theory, Prakriti, Diet, Herbal Medicine, and Panchakarma

Introduction

Ayurveda is one of the world’s oldest holistic healing systems, originating in India over 3,000 years ago. The term Ayurveda combines the Sanskrit words ayur (life) and veda (knowledge or science). It emphasizes health promotion, disease prevention, and personalized treatment based on individual constitution (prakriti). Ayurveda incorporates diet, lifestyle, herbal medicine, cleansing therapies, yoga, and meditation.

Prakriti (Constitution) Assessment

Prakriti is determined at conception and remains stable throughout life. Most people are dual-dosha (Vata-Pitta, Pitta-Kapha, or Vata-Kapha) or have a predominant single dosha.

Dosha Pattern	Prevalence	Characteristics
Vata-Pitta	Common	Combines creativity and determination; prone to anxiety and irritability
Pitta-Kapha	Common	Strong, determined, stable; prone to anger and sluggishness
Vata-Kapha	Less common	Creative with endurance; prone to indecision
Single dosha	Rare (10-15%)	Extremely strong tendency toward that dosha’s characteristics
