Guizotia abyssinica is an annual herb native to Ethiopia, Eritrea and Malawi. It is grown for its edible oil and seed, which is used as bird feed worldwide. The seed is also used for culinary and medicinal purposes in some parts of India, and the oil is used for industrial purposes. It requires moderate rainfall between 1,000 to 1,250 millimetres (39 to 49 in) annually and moist soil to grow properly. The yield of seeds will average 300–400 kilograms per hectare (270–360 lb/acre) under favorable conditions but can produce up to 600 kilograms per hectare (540 lb/acre). It is self-sterile and requires bees for cross pollination. The oil is clear, slow-drying, and edible, with a pale yellow or orange color and a nutty taste and sweet odor. The seed's fatty acid composition is similar to sunflower oil and has high content of linoleic acid.
