Choorna is a Sanskrit
word meaning powder. It is an Ayurvedic
preparation containing fine powders of herbs, roots or minerals after they have been completely dried. Simple choorna consists of only one ingredient while a compound choorna consists of more than one ingredient.
According to Ayurveda, the therapeutic value of most of the substances is greatly increased when they are in their powdered form, especially in the cases of antacids, protective and adsorbents. This is the principle behind choornas and it is easily administrable.
Choorna is generally taken in empty stomach in the morning and it is also taken before meals, as an appetizer and before bedtime for clearing the bowels. Usually choornas are taken with milk, water, ghrita, honey, curd or buttermilk.
Ashwagandhadi Choorna, Avipattikar Choorna, Bajrakshar Choorna and Bilvadi Choorna are some of the choornas.
