Ajwain (Trachyspermum ammi) is a plant that produces small, seed-like fruits similar to caraway and cumin. It comes from the Apiaceae family, which is a group of plants that includes celery, caraway, coriander, fennel, parsley, and parsnips. It goes by many other names, including carom seed, bishop’s weed, and ajowan caraway.

Ajwain seeds have a small amount of oil in them known as ajwain oil. The oil contains thymol, a phenol that gives the fruit its thyme-like smell. Thymol is commonly used to treat digestive problems. It also has antifungal and antibacterial properties.

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.

Many of the essential oils in ajwain, most notably thymol and carvacrol, can help to fight the growth of bacteria and fungi. They may also help to fight bacteria like salmonella and E. coli, which can lead to food poisoning and other stomach issues.
