Limited and preliminary clinical research has examined the efficacy of aniseed toward diabetes, dysmenorrhea, and menopausal hot flashes.

The present narrative review summarizes human and animal studies reporting potential health benefits of aniseed and highlights areas for future research. Nutr Today 2022;57(2):96-109 A nise ( Pimpinella anisum L., family Apiaceae) is an aromatic annual herb native to the eastern Mediterranean region and western Asia (Figure 1) and cultivated in numerous regions such as southern Europe, northern Africa, South America, China, and Japan. Turkey, Egypt, and Spain are major exporters of this herb, whereas Russia, Spain, and Poland are major suppliers of its oil. The small fruit is incorrectly referred to as a seed.

This is due to the precipitation of congeners and by-products of distillation that are most soluble in ethanol compared with ethanol and water. In regional foods, this spice is a part of, for example, German springerle or anise-flavored cookies. For these cookies, anise oil (1/ 2 tsp) or extract (1 tsp) can be added directly to the dough, or on the other hand, toasted aniseeds can be distributed on the cookie sheets before baking. Greek butter cookies (koulourakia), traditionally made for Easter and Christmas celebrations, include aniseed (1/2 tsp) and ouzo (1 tbsp) among its flavorings.
