Plants are of relevance to dermatology for both their adverse and beneficial effects on skin and skin disorders respectively. Virtually all cultures worldwide have relied historically, or continue to rely on medicinal plants for medical care.

Here we document two patients who developed contact dermatitis due to Allivum sativum, and Ranunculus illyricus after applying to the skin in order to relieve the rheumatological joint pain. © Blackwell Munksgaard 2007.
