Any Indian would say their dal tadka is incomplete without ajwain. Also called carom seeds, this spice has a rich aromatic flavour, and is often compared to thyme.
Ajwain has long been used in Ayurveda to get rid of indigestion and gas. Extracts found in the spice may also help relieving peptic ulcers or sores in the small intestine, stomach and esophagus. You can drink ajwain in water to get relief.
Carom seeds may help ease congestion and common cold because of their thymol content. Thymol has anti-bacterial, anti-fungal and anti-inflammatory properties that can soothe congestion. Crush the spice and mix with jaggery. Take the mixture a few times a day!
Anti-inflammatory properties of ajwain could also help you reduce arthritis-related joint pain. All you've got to do is add a spoonful of seeds in a tub of warm water and soak the joints giving you pain. Alternatively, you can apply a paste on the affected areas.
