Classification
Of the Asteraceae family, Rasna is grouped among the Vata-pacifying, anti-inflammatory dravyas. Its bitter taste, heavy quality and heating potency clear Ama and calm Vata-driven pain and swelling.

Frequently asked questions
What is Rasna used for?
Joint pain and stiffness above all, particularly rheumatoid arthritis (Amavata). It is the classical anti-arthritic and the lead ingredient of Maha Rasnadi Kwath, one of the most-prescribed Ayurvedic joint preparations.
What is the dose of Rasna?
Root or leaf powder 3–6 g per day, or decoction 40–80 ml twice daily. As Maha Rasnadi Kwath, typically 15–30 ml with an equal quantity of water, twice daily before meals.
What is Amavata?
The classical term for what largely corresponds to rheumatoid arthritis — painful, stiff, swollen joints combined with digestive disturbance and a coated tongue. Ayurveda treats it as a digestive disorder that manifests in joints, which is why Rasna is both Deepana and anti-inflammatory.
How long does Rasna take to work on joint pain?
Four to eight weeks of consistent use before judging. Chronic joint conditions are worked over three to six months in classical practice, alongside dietary change — Amavata treatment always addresses digestion as well.
Is Rasna the same as Alpinia galanga?
This is a genuine point of confusion. In north India Rasna is usually Pluchea lanceolata; in south India and Kerala, Alpinia galanga is often used instead. Both are used for joint pain. Check which botanical a prescription means.
Are there side effects of Rasna?
Well tolerated at classical doses. It is bitter and warming, so it may aggravate Pitta in excess. Consult a physician in pregnancy.
Can Rasna be used with conventional arthritis medication?
It is commonly used alongside, but tell your rheumatologist. Do not stop prescribed disease-modifying drugs for rheumatoid arthritis to take a herb — joint damage in untreated RA is permanent and accumulates quickly.
