At least essential oils have a use as air freshener and mood lifter. Some may be marginally effective as insect repellent. I’m guessing to be a true bullshit “homeopathic” dilution it has to be in water. However, if essential oils are cut with snake oil* then they become 10,000X more potent, sync up with the earths natural frequencies to heal your DNA and deliver you to a higher spiritual plane. Also it cures E.D., will make you lose weight and allow you to see auras. *Only true for unrefined, organic snake oil from snakes that have been fed undomesticated mice.
