Borage (Borago officinalis), also known as "starflower", is an annual herb native to central and eastern Europe. It grows to a height of 60-100 cm, and is bristly-hairy all over the stems and leaves; the leaves are alternate, simple, and 5-15 cm long. The flowers are small, blue or pink, with five narrow, triangular-pointed petals. It produces plenty of seeds and thus continues to grow and spread from where it is first sown or planted.

The leaves have been found to contain small amounts (10 ppm of dried herb) of the liver-toxic pyrrolizidine alkaloids: intermedine, lycopsamine, amabiline and supinine. They taste like fresh cucumber and are used in salads and soups especially in Germany. One of the better known recipes with borage is the Green Sauce made in Frankfurt. Frankfurter Grüne Sauce, as it is called in Germany, is made from seven herbs: parsley, chervil, chives, cress, sorrel, burnet and borage.

The flower, which contains the non-toxic pyrrolizidine alkaloid thesinine, has a sweet honey-like taste and is often used to decorate desserts and dishes. If frozen into ice-cubes, the flowers become exotic drink coolers.

The oil that is extracted from the seeds (marketed as "starflower oil" or "borage oil") is a good source of gamma-linolenic acid.
