Sensitization and cross‐reaction patterns in Danish Compositae‐allergic patients
Chrysanthemum (Dendranthema) and marguerite (Argyranthemumfrutescens) were the most important suspected sensitizers in both occupationally and nonoccupationally exposed, and cross‐reactions between chrysanthamum and feverfew/tansy/chamomile may partly explain the high prevalence of positive reactions to the 3 last mentioned.

Experimental and chemical investigations revealed that common ivy (Hedera helix susp. Helix) contains 3 compounds which are powerful irritants and moderate sensitizers, and this is the third species of the Araliaceae in which these polyacetylenic sensitizer have been found.

Diphencyprone in the treatment of alopecia areata.
Diphencyprone was found to be as effective as DNCB or squaric acid dibutylester in the treatment of alopecia areata and is more stable and thus more suitable for storage when dissolved in acetone.
Degradation products of monoterpenes are the sensitizing agents in tea tree oil.
The seamy side of natural medicines: contact sensitization to arnica (Arnica montana L.) and marigold (Calendula officinalis L.)
It is concluded that compositae allergy contributes significantly to the epidemiology of contact dermatitis and that sensitization to arnica and marigold cannot be assessed by testing with the Compositae or sesquiterpene mix alone.

The sensitizing capacity of Alstroemeria cultivars in man and guinea pig
Tuliposide A was determined in specimens of Alstroemeria ligtu cultivars of 14 different origins of various colours: its content varied between 1 and 2%.
