The aromatherapist should take a thorough medical history, and a lifestyle, diet, and current health history. Some people report developing allergies to essential oils after using them many times before. If a new allergic response appears, the individual should stop using it immediately and avoid its smell. Essential oils are made by steaming or pressing various parts of a plant to capture the compounds that give the plant its unique fragrance. Those oils can then be inhaled, added to a carrier oil for direct application on the skin, consumed orally (some, not all), or used in household products to clean and sanitize. Opening this Diptyque diffuser is an experience in itself. It arrives in a limited edition box illustrated by the artist Erik Winkowski with cacti, the sun, stars and moon, oranges, palm trees and more emblems of summer. Inside is a ribbed glass jar, rattan reeds, a 200ml bottle of citronelle fragrance and a tiny funnel.

Pop a couple of drops of lavender oil on your pillow for a good night’s sleep or spray the sleep mist around your bedroom just before bedtime. One mouse study found that ingesting a combination of thyme and oregano essential oils helped induce the remission of colitis. Two rat studies on caraway and rosemary oils found similar results ( 26, 27, 28).

However, while these test-tube study results are interesting, they do not necessarily reflect the effects that these oils have within your body. They don’t prove that a particular essential oil could treat bacterial infections in humans. Summary

Vergis, J., Gokulakrishnan, P., Agarwal, R.K., & Kumar. A. (2013, October 11). Essential oils as natural food antimicrobial agents: A review. Each essential oil has its own chemical makeup and reason for use, so it is important to speak with a trained aromatherapist, nurse, doctor, physical therapist, massage therapist or pharmacist before applying or using an oil for healing purposes. Although highly fragrant, concretes contain large quantities of non-fragrant waxes and resins. Often, another solvent, such as ethyl alcohol, is used to extract the fragrant oil from the concrete. The alcohol solution is chilled to −18°C (0°F) for more than 48 hours which causes the waxes and lipids to precipitate out. The precipitates are then filtered out and the ethanol is removed from the remaining solution by evaporation, vacuum purge, or both, leaving behind the absolute. Essential oils are obtained through distillation (via steam and/or water) or mechanical methods, such as cold pressing.
