Health Benefits

Manage - Digestive issues 

Active enzymes in ajwain improve the flow of stomach acids, which can help to relieve indigestion, bloating, and gas. The plant can also help to treat peptic ulcers as well as sores in the esophagus, stomach, and intestines.

In pain management

Ajwain can also help to soothe pain and swelling. Crushed fruit can be made into a paste and applied to the skin at the joints to treat arthritis pain. Alternatively, you can fill your tub with warm water and add a handful of seeds for a soothing bath.

Due to the anti-inflammatory properties of thymol and other essential oils, ajwain can help to reduce pain associated with toothaches. Thymol may also help to improve your oral health by fighting bacteria and fungi in the mouth.  

Upper Respiratory Tract Infections

Ajwain (carom seeds) has bacteriostatic, bactericidal and antibacterial actions, which helps to fight off upper respiratory tract infections. In many cases with chronic upper respiratory tract infections, bad odor with the sputum and altered taste of mouth due to it is a main concern reported by patients. 

In such cases, Ajwain is a highly useful remedy. It reduces microbial growth and thickness of the mucus, and increases the expulsion of the accumulated mucus content from the lungs.


However, Ajwain (carom) can help in all types of intestinal worms by stopping the growth of parasites, but is reported by ayurvedic practitioners that it is more effective in hookworm infestation.

Its extract called Ajwain Sat (Carom seed extract) is used in dosage of 125 mg twice daily for a week to eradicate hookworm from the alimentary canal.
