Importance of Vishghan Dravya in Ayurveda

Vishghan Dravya refers to anti-toxic herbs in Ayurveda that are crucial in detoxifying the body and neutralizing the harmful effects of toxins (Visha). These herbs play a vital role in Rasa-Shastra (Ayurvedic alchemy) and are used to counteract internal and external toxins, including poisonous bites, food poisoning, environmental toxins, and metabolic waste accumulation. Vishghan Dravyas are also key components in Ayurvedic Panchakarma therapies, particularly Virechana (purgation) and Rakta Mokshana (bloodletting), to cleanse the body and restore balance.

Dosha-Dhatu Physiology of Vishghan Dravya

The anti-toxic nature of Vishghan Dravyas directly influences the Tridosha (Vata, Pitta, and Kapha) balance and helps regulate Sapta Dhatus (seven body tissues).

1. Effect on Doshas:

• Vata Dosha: Helps control excessive dryness and neurological disturbances caused by toxins.

• Pitta Dosha: Reduces excessive heat, inflammation, and oxidative stress in the body.

• Kapha Dosha: Clears mucus buildup and prevents metabolic sluggishness caused by toxin accumulation.

• Rasa Dhatu (Plasma): Purifies plasma and enhances blood circulation.

• Rakta Dhatu (Blood): Removes impurities from the bloodstream and protects against skin diseases.
