“Also known as Dill Herb Oil. The dill plant, Anethum Graveolens, is one of the many umbellifers which supply us with aromatic seed or culinary herb material. The plant grows wild in most parts of Europe, the Middle East up to southern Russia, all around the Mediterranean Sea widely in India and Fareast Asia, in Italy and in Kenya. The plant is distinguished by having yellow flowers (like the pimpinella plant) in contrast to the white flowers of most other umbelliferes.”
