Essential oil from dill – step by step

Steam distillation using dill as an example

With the right still, it is very easy to make essential oils and hydrosols yourself. The extraction of essential oil from dill tips is shown here using the LEONARDO® CLASSIC still. Because of the low oil content of the dill tips, the LEONARDO® is very well suited for this.
