Due to their healing properties, essential oils are used as an alternative to natural medicine. However, as with medications, they should be used in moderation and be aware of possible side effects. Some essential oils can be harmful or even toxic, especially when taken orally.
The main rule is: never use
essential oils undiluted. Orally or topically. What else should you watch out for? Which oils can do more harm than good if you're not careful?
Tea tree oil
An oil with a simple, woodsy, and medicinal scent. Traditionally used for its antiseptic and antifungal properties, it supports the treatment of fungal infections. However, when taken orally, it can pose a risk. What are the risks? Internal use of tea tree oil may expose you to diarrhea, nausea, vomiting, rash, stomach pain, hallucinations, drowsiness, coma, balance disorders, stomach upset, and bleeding. In rare cases, topical application of the oil can cause allergic reactions. Young boys should not use tea tree oil together with lavender oil – it has side effects on their hormonal balance and can result in gynecomastia, or breast enlargement.
Peppermint oil
Peppermint helps with a variety of health ailments, from calming an upset stomach to relieving headaches to alleviating the symptoms of irritable bowel syndrome. However, peppermint oil should definitely not be given to infants and young children. Applying it to the face can cause breathing problems, which can be life-threatening. Use peppermint oil with caution if you are taking medication for diabetes or high blood pressure.
Rosemary oil
Rosemary essential oil is used in products that stimulate hair growth. It is a remedy for indigestion and muscle pain. However, it can be toxic when taken internally. Rosemary oil should not be taken by people with hypertension, ulcers, ulcerative colitis, or Crohn's disease. The oil may interact with antiplatelet medications, diuretics, and ACE inhibitors.
Eucalyptus oil
A popular ingredient in flu and cold remedies. Used to soothe respiratory and arthritic problems. Despite its wide range of uses, it carries certain risks. It should not be taken by children and should be avoided by pregnant and breastfeeding women. Eucalyptus oil can trigger asthma attacks, so asthmatics should use it with extreme caution.
