Analysis of Purīṣavirañjīya Dravya in Ayurveda
Introduction
Ayurveda, the ancient science of life, is based on the principles of dosha, dhātu, and mala equilibrium to maintain health and well-being. Among various classifications of medicinal herbs, Purīṣavirañjīya Dravya holds a crucial place in regulating and optimizing stool color, consistency, and overall bowel health. The term Purīṣavirañjīya is derived from two Sanskrit words:
- Purīṣa – Meaning stool or feces
- Virañjīya – Meaning substances that influence its color and appearance
This category of dravyas includes herbs that help in correcting stool abnormalities, ensuring proper digestion, absorption, and excretion. It plays a significant role in managing malabsorption syndromes, irritable bowel syndrome (IBS), jaundice, anemia, and chronic gastrointestinal disorders.
Pharmacological Importance in Ayurveda
Purīṣavirañjīya Dravya exerts its influence on bowel health by correcting agni (digestive fire), improving pachana (digestion), facilitating proper mala pravṛtti (bowel movement), and balancing rakta and pitta dosha. These herbs act as:
- Pittahara (Pitta-pacifying agents) – Useful in jaundice, hyperbilirubinemia, and acidity-related stool changes.
- Raktaprasādana (Blood purifiers) – As abnormal stool color often reflects liver or blood-related disorders, these herbs help purify the blood.
- Dīpana and Pācana (Digestive stimulants and digestives) – Assist in improving the metabolism of ingested food.
- Anulomana (Regulators of downward movement of Vata) – They regulate proper elimination of waste products.
Impact on Dosha-Dhātu Physiology
Effect on Doshas
Vata Dosha:
- When aggravated, Vata can cause dry, hard stools or irregular bowel movements.
- Purīṣavirañjīya herbs with snigdha (unctuous) and anulomana (downward moving) properties help pacify Vata and improve stool consistency.
Pitta Dosha:
- Aggravated Pitta can lead to yellowish or greenish stools, loose motions, and hyperacidity.
- Tikta (bitter) and sheeta (cooling) herbs in this category help to pacify Pitta and normalize stool color.
Kapha Dosha:
- Excess Kapha leads to sticky, mucous-laden, pale stools with heaviness.
- Rūkṣa (dry) and deepana (digestive stimulant) herbs help remove excess mucus and regulate digestion.
Effect on Dhātus (Tissues)
- Rakta Dhātu (Blood Tissue): Many of these herbs are raktashodhaka (blood purifiers), which help in correcting jaundice and anemia-related stool discolorations.
- Rasa Dhātu (Plasma Tissue): They optimize nutrient absorption, preventing disorders like chronic diarrhea and malabsorption syndromes.
- Mamsa and Meda Dhātu (Muscle and Fat Tissues): If not properly digested, undigested fats in stools (steatorrhea) indicate improper metabolism, which these herbs help correct.

- Grahani (Malabsorption Syndromes)
- Kamala (Jaundice)
- Pravahika (Dysentery)
- Atisara (Diarrhea)
