Essential oils gained popularity recently and have been utilized for their assumed health benefits. These oils are created using different plant products and utilized in various ways. The oils can be diffused into the air which is called aromatherapy, applied topically on the skin and some are even ingested orally. Even though these essential oils are derived from natural plant sources, it does not mean that they cannot trigger side effects particularly allergic reactions when used.
Contact dermatitis
The common allergic reaction to essential oils is no other than contact dermatitis. The rash due to essential oils is characterized as itchy bumps that manifests at the area of contact with the oil.
The rash appears strikingly similar to poison oak with blisters and even peel once it starts to resolve. It is also likely to end up with systemic contact dermatitis after using essential oils orally. In such cases, an individual ends up with a generalized body rash and/or abdominal pain and diarrhea.
It is important to note that contact dermatitis can also occur among individuals who have previous rashes to fragrances or allergy symptoms linked to weed pollens. Those who have this history must be careful when using any essential oils and must consider patch testing by placing a small amount of the oil on the skin at the fold of the elbow at least 2 times a day for 3-5 days.
In cases there is no reaction at the area where the oil was applied after the 5th day, it is not likely that the individual is allergic to the oil. If the skin at the test site turns itchy and red or the skin starts to blister and peel, the oil must be avoided.
Nasal allergies and asthma triggered by essential oils
Individuals who have asthma and nasal allergies particularly those who are sensitive to weed pollens must be careful when using essential oils particularly when diffusing or ingesting them.
Remember that essential oils are made out of different plant products usually weeds that might contain allergens. The ingestion or inhalation of these oils can trigger symptoms of nasal allergies or even asthma.
Non-allergic rhinitis
Individuals who do not usually suffer from nasal allergies might end up with nasal symptoms after using essential oils. The strong odors from essential oils can trigger the nasal symptoms such as runny nose, sneezing, postnasal drip or nasal congestion. Remember that these symptoms are not always due to nasal allergies.
Those who do not have allergies can still end up with symptoms due to the irritant effect from the strong odors. Even today, there is no test for non-allergic rhinitis. The usual treatment for non-allergic rhinitis is avoidance of the irritant triggers.
