Chaste is primarily grown in countries with a temperate climate, such as Greece, Italy, and Spain. It is a hardy shrub that can reach up to 20 feet in height and can grow in a variety of well-drained soil types. The plant flowers in the summer, with small, fragrant lilac or white blooms, and produces small, dark brown to black fruits in the fall.The production of chaste berry involves harvesting the dried, ripe fruit from the plant and then crushing, grinding, or milling it to extract the active compounds. The extract is then dried and processed into different forms such as powders, capsules, and liquid extracts. Chaste is also available in its whole form, which is used for making tea infusions or adding to food and beverages.
