Botanical source

Anethum sowa is a distinct dill species of South Asia, particularly India and Pakistan. The Hindi name 'sowa' and Sanskrit 'satapashpi' reflect traditional use as both spice and medicine.

The oil is steam-distilled from the seeds. Differs markedly from European dill (Anethum graveolens) in chemistry because of its dill apiole content, a phenylpropene similar to parsley apiole.

Family Apiaceae.
