As per Ayurveda, onion normalizes vata and increases kapha and pitta. Hence it is used in diseases which occur due to vitiation of vata.
It acts as an anti-inflammatory agent and reduces pain. Ayurvedic texts recommend its use in sciatica, arthritis and other diseases which involve bones, joints and peripheral nervous system.
