Sensitization is triggered by the quinone primin (2-methyl-6-pentyl-1,4-benzoquinone). Sensitizing potency: Very strong. Sensitization frequency: Occasional.
The medically used primrose species (Primula veris, Primula elatior also called Priula officinalis) contain almost no primin.
Clinical pictureThis section has been translated automatically.
The literature reports numerous cases of irritant and allergic reactions after contact with the cup primrose. The most common allergic contact eczema today is observed in connection with domestic or hobby gardening activities. Occupational primrose allergies in gardeners or florists are rare. Cross-reactivity can occur in contact with other plants and wood species containing quinones with related structures, such as exotic wood species ( Dalbergia species, rosewood) such as teak or rosewood. Related chinoid constituents are also found in other primrose species, orchid species, etc. as well as marine animals (e.g. in natural sponges).
