La Compagnie des Sens has developed this guide in order to draw up a non-exhaustive list from the bibliography of essential oils that can be used by people with asthma or epilepsy. Although these do not present any particular contraindications, it is important to note that in general essential oils are not recommended for epileptics and asthmatics, unless with medical advice. Some will in fact be more inclined to cause an asthmatic or epileptiform reaction but all present a potential sensitizing risk. Do not hesitate to consult a healthcare professional (doctor and/or pharmacist) in case of persistent doubts and to carry out an allergy test before any use.

Essential oils are, remember, substances composed of numerous chemical molecules capable of acting on our body.
In the case of asthma, the fragility of the bronchi and their state of constriction induce increased reactivity of the respiratory system. It is then important to consider the volatility of aromatic molecules which can represent a threat to an asthmatic subject, in particular essential oils that are too expectorant or oxygenating such as those containing a significant rate of’eucalyptol (1,8-cineole), for example the essential oils of Eucalyptus Globulus, Radiata, Smithi, etc. The irritant and allergenic action of other molecules, such as terpene aldehydes (citronnellal, geranial, neral, etc.), terpene ethers and terpenes, requires a careful use with a maximum of 50% final concentration of essential oils. Indeed, if this dilution seems particularly essential for the cutaneous route, it is even more so for all mucous membranes.
There neurotoxicity terpene ketones, lactones and, to a lesser extent, terpene oxides contraindicate their oral use in neurologically affected patients, thus concerning epileptics and people at risk of convulsions. Careful use, and for all available ways of use, it is important to seek advice from an aromatherapist or a health professional (doctor and/or pharmacist).
