The induction of contact dermatitis is a highly effective defence mechanism shown by many plants; it can result from contact with living or damaged plant materials (1), and may occur in the patient immediately, hours after contact, or even only after subsequent exposure. Plants and plant products are divided into several different groups, and, from a clinical perspective, it is important to be able to recognize the plant involved. The stinging nettles constitute one of the five groups, and… 
Plant-Induced Urticaria
This chapter focuses on plant-induced urticaria as well as effective treatments and preventive strategies for irritant contact dermatitis.
Neurotoxic peptides from the venom of the giant Australian stinging tree
The venoms of Australian Dendrocnide species contain heretofore unknown pain-inducing peptides that potently activate mouse sensory neurons and delay inactivation of voltage-gated sodium channels, providing an intriguing example of inter-kingdom convergent evolution of animal and plant venoms with shared modes of delivery, molecular structure, and pharmacology.


Plants and plant products that induce contact dermatitis.
The production of dermatitis by contact is a highly effective defence mechanism exhibited by many plants, and poses a clinical problem both for the physician and the veterinary surgeon.
Stinging nettle dermatitis.
The stinging nettle (Urtica dioica) is a common weed that can cause a wide range of cutaneous reactions that act to cause itching, dermatitis, and urticaria within moments of contact.
Identification of oxalic acid and tartaric acid as major persistent pain-inducing toxins in the stinging hairs of the nettle, Urtica thunbergiana.
Oxalic acid and tartaric acid were identified, for the first time, as major long-lasting pain-inducing toxins in the stinging hairs of U. thunbergiana.
A case of canine poisoning with New Zealand Tree Nettle (Ongaonga, Urtica ferox)
There is widespread anecdotal awareness, but published reports of poisonings and treatment protocols are scarce in the human literature (McGouran 2010) and rare in the veterinary literature.
