The side effects depend on what oil you’re using & how you’re using it.

• Citrus-based oils (orange, lemon, & bergamot) are photo-sensitizers. You can get a sunburn easily.
• Tea tree & eucalyptus are toxic to the nervous system and liver. Use care around animals, infants, the elderly, and pregnant women.
• Mugwort, pennyroyal, & wormwood can cause contractions, so don’t use during pregnancy.
• Be cautious if you have respiratory conditions or strong reactions or allergies to fragrances.
• They do release off-gases. So limit your use.

Safety testing shows very few risks when used as directed.

• 15 to 60 minutes is the ideal limit—never breathe in essential oils for more than one hour at a time.
• Always follow the instructions on the bottle.
• If you’re taking any medications or suffer from a chronic health condition, ask your doctor first.
• Essential oils must be used correctly to yield health rewards.
• A diffuser is the most effective way to disperse essential oils into the air. Use one or two drops of one oil at a time.

If you stick within the safe time limit and open a window when you're done, you can practice aromatherapy every day.

Follow these tips to make sure you purchase genuine products:

• Beware the aromatherapy label, often on diluted oils laced with synthetic fragrances.
• Look for 100% pure and organic oils free of fillers, pesticides, and synthetic chemicals.
• If a label says therapeutic grade or steam distilled, even better.
• Most essential oils have long shelf lives—more than a year if stored in a cool, dry place. If the shop you're in is hot or humid, buy elsewhere.
