It has been found that some essential oils can be harmful when used in incorrect doses or concentrations. Animal and laboratory studies have revealed that these oils can contribute to the development of tumors and other negative changes in the body. In addition, they can damage the skin, liver, and other organs if used improperly. Consuming essential oils is not safe and can lead to significant poisoning even if only small amounts are ingested.
For example, anise Pimpinella anisum (L.) can be deadly when used in excessive doses or with prolonged use for two or three weeks. It has the potential to cause circulatory and nervous system disorders. Cats are particularly vulnerable to essential oils, as exposure can result in severe liver damage, liver failure, respiratory failure, seizures, and even death. On the other hand, some essential oils may be beneficial when used correctly.
A study has shown that they may be effective in reducing anxiety and fear regarding childbirth. Furthermore, they can be used to relieve stress, pain, nausea, and even prevent pressure ulcers in hospitals and clinics. Helichrysum essential oil has been found to have anti-inflammatory and antimicrobial qualities. It is important to note that essential oils should never be used internally unless you have received advanced training and certification or are acting under the guidance of a trained professional.
Additionally, it is important to check the shelf life of essential oils before using them. If traces of essential oils are left on your hands and you rub your eyes or scratch the inside of your ears, you could experience a serious adverse reaction. When it comes to pregnancy, there are some essential oils that should never be used while others are considered safe for prenatal massages or through the diffuser method. It is also important to note that since essential oils are generally not regulated, it can be difficult to know exactly what is in the bottle: what species of plant, what concentration of active ingredient, or if there are any contaminants.
Finally, it is important to use caution when using essential oils on pets as they can cause more stress rather than calming them down. In conclusion, it is important to use essential oils with caution as they can be beneficial when used correctly but can also be harmful if used improperly.
