Skin Rash or Hives
An allergic reaction to natural essential oils can often result in skin rash or hives. These are typically red, itchy, and can pop up anywhere on the body where the oil was applied.
Respiratory Problems
Respiratory problems such as shortness of breath, wheezing, or a feeling of tightness in the chest may occur. This is because, in some people, essential oils can trigger asthmatic symptoms or exacerbate existing respiratory conditions.
Swelling or Inflammation
Exposure to essential oils can lead to swelling or inflammation, particularly around the area where the oil was applied. In more severe cases, this could also include swelling of the tongue, throat, or lips.
Eye Irritation
Eye irritation is another symptom of an allergic reaction to essential oils. If the oils get into your eyes, they might become red, watery, itchy, or feel like they are burning.
Headaches or Dizziness
For some people, the potent smells of natural essential oils can lead to headaches or feelings of dizziness. This can also be a sign of an allergic reaction.
Stomach Upset
Stomach upset or nausea can also be a symptom of an allergic reaction to essential oils, particularly if they have been ingested. Remember, many oils are not safe for consumption and can cause severe internal irritation if swallowed.
