Many essential oils are steam distilled, which involves simmering the plant material to produce steam, which travels through a tube, which is then run through cold water. The liquid that forms from condensation will be in two parts, a water compound, and an oil compound. The water compound is where floral waters, such as lavender and rose water, come from. The oils that rise to the top are DIY essential oils.
Make sure all your instruments are in stable positions. Depending on the tools you’re using and the shape of your pipe, you may have to work a little bit to find a safe, stable setup for all of your still components. Put the lid on the pressure cooker with the pipe attached to it, run the pipe through your cooling tub, and position the open end of the pipe over your essencier. Make sure the pipe is at a comfortable angle and nothing will get knocked over.
Young children and the elderly may be more sensitive to essential oils. So you may need to dilute them more. And you should totally avoid some oils, like birch and wintergreen. In even small amounts, those may cause serious problems in kids 6 or younger because they contain a chemical called methyl salicylate. Don’t use essential oils on a baby unless your pediatrician says it’s OK.
