Importance of Rasayan Dravya in Ayurveda

Rasayan Dravya plays a crucial role in Ayurveda as rejuvenating and life-enhancing substances that promote longevity, immunity, mental clarity, and overall well-being. The term ‘Rasayana’ is derived from ‘Rasa’ (essence or nourishment) and ‘Ayana’ (path), signifying the path of nourishment to sustain bodily tissues and delay aging. These herbs and formulations enhance Ojas (vital essence), Tejas (cellular intelligence), and Prana (life energy), making them essential for promoting health and preventing disease.

Dosha-Dhatu Physiology of Rasayan Dravya

Rasayan Dravya work at a fundamental level in balancing Tridosha (Vata, Pitta, Kapha) and enhancing Sapta Dhatus (seven bodily tissues) for optimal physiological function.

1. Effect on Doshas:

• Vata Dosha: Provides nourishment, stability, and hydration, preventing premature aging and dryness.

• Pitta Dosha: Cools excessive heat, reduces oxidative stress, and enhances liver function.

• Kapha Dosha: Improves metabolism and prevents excessive mucus accumulation, ensuring cellular detoxification.

2. Impact on Dhatus (Tissues):

• Rasa Dhatu (Plasma): Enhances hydration and nutrient absorption.
