you wil need Acetone/ nail polish remover, 2 medium-sized clean bowls Potato masher (or similar implement to mash plant matter) Cheese cloth (to strain liquid) Rubber tube siphon.

Put the flowers in a bowl and mash it up. Place about five of the same flowers and stems with their leaves (if appropriate) into a bowl. Mash them so that every flower,stem and leaf has a cut opening to its inside juice. The overall effectiveness of your finished product can be guaranteed by the consistent and thorough pulverizing of your plant matter.

Pour the acetone solvent in the bowl containing the plant mash. Be sure that all parts of the plant mash are completely covered by the Acetone.

Store your bowl of "solution" in a well-ventilated, cool place—preferably outside.
While it is important that your solution stays cool to do its magic, be certain it is also sheltered from direct sunlight, flying insects and other such typical outside irk. A screened porch can be the perfect solution for your solution. Wait 1 week.

Filter the mash after the week waiting period. Take the cheesecloth and cover the opening of the bowl with it. Gently separate the plant matter from the liquid by pouring the liquid substance into another bowl. You should have two liquids now, one on top of the other.

Draw off the top liquid oil using the rubber tube siphon. This top oil is the essential oil. You may even siphon off the bottom half of the two-tone liquid—which is the left-over water and whatever impurities that were present in the solution during its process time.

But extracting the oils is a long process, and she’ll need large amounts of the plant material.

Here’s a good step-by-step regarding the process:
