    Area of Science:

    • Dermatology
    • Allergology
    • Toxicology

    Background:

    • Aloe vera is widely used for its purported medicinal properties.
    • Potential adverse reactions to topical and oral aloe vera are not well-documented.
    • Hypersensitivity reactions can range from mild irritation to severe dermatitis.

    Observation:

    • A 47-year-old male patient presented with generalized nummular eczematous and papular dermatitis.
    • The patient reported a four-year history of consistent oral and topical aloe vera use.
    • Symptoms were presumed to be related to contact urticaria from aloe vera exposure.

    Findings:

    • Patch testing with aloe vera yielded positive results in the patient.
    • This confirmed a diagnosis of hypersensitivity to aloe vera.

    Related Experiment Videos

  • The findings suggest a causal link between aloe vera exposure and the observed dermatological conditions.

    • Implications:

    • Prolonged oral and topical use of aloe vera can lead to hypersensitivity reactions.
    • Contact urticaria and eczematous dermatitis are potential adverse effects.
    • Healthcare providers should consider aloe vera as a potential allergen in patients with unexplained dermatitis.
