Aromatherapy Cautions

There is a vogue for many scientifically nonqualified aromatherapists to practice clinical aromatherapy, in which they prescribe the internal usage of essential oils. Internal prescribing involves oral, rectal, and vaginal intake however, the use of tampons soaked in various potentially toxic essential oils, such as the various tea tree oils, with variable biological potential could have a possible harmful effect on the delicate internal mucosal membranes. The possibility of misdiagnosis of a urogenital condition by medically unqualified aromatherapists or by the patients themselves could also result in serious consequences. 

More than 10,000 new compounds have been isolated from bacteria, fungi, microalgae, seaweed, sponges, soft corals, opisthobranch mollusks, bryozoans, echinoderms, and ascidians. 

Most of the highly bioactive marine metabolites are also highly toxic, which is very serious. If enough materials are available, parent compounds could be modified to reduce their toxicity or to improve their therapeutic efficacy. However, such attempts have not been accomplished because of limited amounts of materials and their highly complex structures, except for readily synthesized substances such as didemnins and dolastatins. 

Of course, the discovery of new structures is very important. Marine microbes are relatively new targets for such research. Bacteria and fungi isolated from marine environments, i.e., seawater, sediments, and marine organisms, often produce metabolites identical or similar to those from terrestrial species. 

Phytoplanktons produce a wide variety of unusual metabolites with strong bioactivities and frequently unprecedented structural features. However, there are some problems — low growth rates, low productivity of metabolites, and complexity of structures are negative factors (Fusetani, 2000). Table 46.1 and Table 46.2 list a few of the more than 10,000 potential drugs that are being isolated from marine life.

The essential oils used in aromatherapy are a potent mix of chemicals, with a vast range of properties and reactions, and should be handled with caution. A useful working definition of aromatherapy is the use of essential oils in a controlled manner. In order to ensure safe and effective use of these oils, the... 

Phenol is not actually an alcohol, although the molecular structure is similar. The difference between alcohols and phenols should be recognized. Phenols need to be used with caution in aromatherapy. 

CAUTION Methyl salicylate makes up 90% of essential oils of wintergreen and birch, They are not suitable for aromatherapy, although the pungent winter-green is often an ingredient in sports gels for external use only. 

Most aromatherapy books state that peppermint is nontoxic, nonirritant when diluted and possibly sensitizing owing to its menthol content. It is often advised to use it in moderation. However, it should be used with caution and is contraindicated for use with babies and young children. The high menthol content has been shown to cause breathing problems in infants. It is irritant to mucous membranes and may exacerbate skin irritations and contact dermatitis. External use necessitates a concentration of not more than 3%. Internal use should be under the direction of a qualified medical practitioner, medical herbalist or pharmacist and is beyond the scope of aromatherapy. 

Pregnancy and aromatherapy can be a controversial issue caution is always advised for the first three months, but careful choice and use of essential oils can be very helpful.
