Eranda Moola

Ricinus communis

Eranda Moola (Ricinus communis) is a plant drug, also called Eranda, Aramdi and Remrii. Ricinine has good oral bioavailability (>50%) with rapid absorption. Flavonoids from root have moderate bioavailability (15-25%). Unlike the oil from seeds, root preparations are primarily used for anti-inflammatory and Vata-pacifying actions rather than purgation.

Reviewed by Dr. Awadesh Pratap Singh, BAMS, on 11 October 2026. What that review covered.

Consult a qualified vaidya before acting on anything here. Ayurvedic practice is prescribed to a person, not to a condition: the same dravya is given, withheld or substituted depending on your constitution, your agni, the season and what else you are already taking. A page cannot know any of that. Self-prescribing from a reference is how the wrong preparation, the wrong dose or the wrong anupana gets used.

Educational reference only. Nothing on this page is medical advice, a diagnosis, or a recommendation to take anything. Traditional uses and research findings are reported as published, not as claims about what any product does. If you take prescribed medication, raise any interaction with the prescriber rather than acting on a page. See our editorial standards.
