Artemis - Artemisia arborescens
Blue Artemis is picked/harvested as near
as possible to bloom. The soft tender stems, top leafy parts and flowers
are harvested and distilled as soon as possible after picking. In order to
keep the hydrosol blue and to collect as much essential oil as possible it
is important to use glass as the receiver. If your still holds 5 lbs of
plant material, use 3-5 gallons of water. Steam and water distillation is
best for hydrosol production, while steam distillation is best for
essential oil quantity.
Blue Artemis (A. arborescens) is a powerful, camphoraceous-smelling
deep indigo blue essential oil. When freshly distilled the hydrosol has
very visible particles of essential oil floating in the pale blue fragrant
Do not use any plastic, PVC or non-glass or non-metal in the distillation
of this plant. The essential oil will be absorbed by rubber or plastic
tubing rendering it dark blue. The eo will also collect on the inside of a
plastic container. You must use glass as your receiver.
To keep the essential oil in solution and the hydrosol blue, pour the warm
hydrosol (just off the receiver) as soon as possible into 1-quart size
glass containers. Your original glass receiver will have collected a layer
of the dark essential oil on the inside rim. Dissolve this with 95% ethyl
alcohol. Divide this now blue alcohol (with dissolved essential oil) into
as many parts as you have quarts of hydrosol and add it to the hydrosol.
In the best of times you will have only added up to 5% alcohol to each
bottle of still warm hydrosol — but this small amount of alcohol will
keep the essential oil in solution, the hydrosol will stay nice and blue
and the alcohol will only be 5% of the total and help to keep mold and
bacteria at bay.
