An essential oil is a concentrated hydrophobic liquid that contains volatile aroma compounds derived from plants. They are usually extracted from the plants by distillation mostly using steam, solvent extraction and expression. They are used in a number of products such as perfumes, soaps, flavouring of foods and drinks and cleaning agents. Organic essential oils are therefore obtained from natural sources as opposed to being chemically produced.
These extracts are very valuable to people who practice alternative medicine and in the health community, they are not taken seriously. It is therefore a very difficult task to find references of the specific benefits. The transmission of some resistant pathogen strains can also be controlled by the use of essential oils which is according to several studies.
A good number of these products are not to be taken in large amounts especially by mouth as they can cause a burning feeling or salivation. This can result into belching as it has a carminative effect in the stomach causing the gastric sphincter to close. Eucalyptus oils, camphor, capcaisin, menthol and anise are the worlds most beneficial with others offering insignificant benefits.
The tea tree oil is an example of an extract that can cause dermatitis with many affecting the skin and mucous membranes in a negative way. Menthols on the other hand are famous for bringing a cold feeling followed by a sense of burning caused by their effect on heat-sensing nerves. Dentists in the ancient times used clove oil as an antiseptic and anaesthetic.
Some of these extracts are claimed to possess an uplifting effect on the mind. However, such claims are not necessarily false but are difficult to quantify. The main solvents for these extracts are pure ethanol and polyethylene glycol due to the fact that they are immiscible with water. The danger of an essential oil is generally associated with its level or grade of purity and not the effect it has on the body.
Most of these substances are needed for their aroma therapeutic properties and should never be used on the skin especially in their crude form. Some of them are known to spur allergic reactions in individuals, cause severe irritation and become hepatotoxic with time. Some have photosensitizing properties particularly those that are obtained from citrus plants and they increase the skins exposure to sunlight.
Industries that deal with these products are required to consult the safety data sheets to determine their hazards are handling methods. This is because even grade oils meant for therapy can pose risk to pregnant women and epileptic individuals. These extracts are known to be harsh towards certain materials such as plastics and rubbers thus the correct handling equipment should be used.
Therapeutic essential oils have been known to have traces of pesticides and are the reason why these products are sought by practitioners. For the ingestible ones, they should be taken in their correct dosage which is usually safe for consumption in small quantities. Government standards should be used in the case of concerns of pesticide traces.
