Green Living Channels Essential oils, used for everything from insect repellents to aromatherapy and fragrance, are very strong and need to be used with care, but they can cause environmental health problems if the brand doesn't provide pure oils.
Some oils have petroleum-based solvents added, which can be very toxic.
Put a few sample drops of your oils on a blotting paper. Pure essential oils will not leave any residue once they have evaporated, whereas petroleum solvents will. Each individual person, fabric, or material may react differently to a particular suggested use. It is recommended that before you begin to use any formula, you read the directions carefully and test it first. Should you have any health care-related questions or concerns, please call or see your physician or other health care provider.
