What is Dill?
This dill plant goes by a few other botanical names: Fructus anethi and Peucedanum graveolens. It is also called American or European dill. However, it should not be confused with Indian dill, or Anethum sowa.
The plant itself features feathery green leaves, a smooth stem, and flower heads that are large and full of many small yellow flowers. These contain the small flat dill seeds we see in cooking.
Dill has been a garden favorite throughout history since the Middle Ages. The herb has been used in both culinary and medicinal purposes. It is the main ingredient in gripe water for babies and is still listed in the British/European pharmacopoeias. 
The plant is no longer restricted to its countries of origin; it is now cultivated worldwide, including in the United States, China, Europe, India, and more.
The oil, which is produced through steam distillation of the seeds, is mainly produced in the countries of England, France, Germany, Hungary, Spain, and the USA.
Dill seed essential oil is a colorless to light yellow liquid. Always look for the botanical name so you do not accidentally end up with Indian dill, which is of a different chemical makeup and contains dillapiole, which is an oral toxin and psychotropic. 
While most oil on the market is from the seed, there is also oil distilled from the fresh or dried herb. Both of the oils are used in beverages and foods, especially in condiments and pickling.
Dill oil blends well with angelica seed (Angelica archangelica), bergamot (Citrus bergamia), cardamom (Elettaria cardamomum), fennel, sweet (Foeniculum vulgare), juniper berry (Juniperus communis), nutmeg (Myristica fragrans), and spice and citrus oils.

Dill Essential Oil Research, Facts, and Studies
In a study from 2012, Iranian researchers set out to determine whether dill oil was effective in the induced inflammatory response in rat paws compared to Diclofenac, a traditionally-prescribed treatment for inflammation.
They discovered that the dill oil was significantly effective in reducing inflammation and that this effect is due to the impact of the carvone content in the oil itself.

In a report published in 2016, researchers detailed the effects of dill seed essential oil on several strains of microorganisms:
- Bacillus subtilis
