Coriander Seeds (Dhania).Coriander is the seed of a small plant. The seeds are almost spherical, one end being slightly pointed, the other slightly flattened. There are many longitudinal ridges. The length of the seed is 3 - 5 mm (1/8" - 3/16") and the colour, when dried, is usually brown, but may be green or off white. The seed is generally sold dried and in this state is apt to split into halves to reveal two partially hollow hemispheres and occasionally some internal powdery matter. In Asia the herb is used against piles, headache and swellings; the fruit in colic, piles and conjunctivitis; the essential oil in colic, rheumatism and neuralgia; the seeds as a paste for mouth ulceration and a poultice for other ulcers. Coriander contains an antioxidant that helps prevent animal fats from turning rancid. It also contains substances that kill meat-spoiling bacteria and fungi.
