Introduction A detailed review of mechanical irri.tams, stinging nettles, phototoxic compounds and contact allergens causing dermatitis in men is presented. The producing ~ l a n t s and their dermatitis causing constituents are listed. The chemical structures and the botanical sources of I primary irritants are also discussed. 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… 

Plants and Plant Products

Contact dermatitis from plants or plant products may occur by several mechanisms and reactions of mixed aetiology, for instance irritant reactions superimposed on allergic reactions, are often seen, while mechanical plus chemical irritant effects are evoked by, for example, stinging nettles.

Skin contact with a stinging tree requiring intensive care unit admission

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

Dermatitis-inducing psoralens on the surfaces of seven medicinal plant species

AbstractSeven species of plants from the families Umbelliferae, Rutaceae, and Leguminosae known or suspected to cause photophytodermatitis were quantitatively analyzed for psoralen, 8-methoxypsoralen

Isolation and characterization of irritant components of Euphorbia pilulifera L.

The dermatological investigation of irritant principles from locally occurring Euphorbia pilulifera was carried out and the chloroform extract of this weed was found most irritant to rabbit ' s skin.

Airborne contact dermatitis apparently acquired as a result of using pericarp juice from an Indian marking nut as a home remedy to treat patchy hair loss

Various medicinal activities have been ascribed to various parts of the Indian marking nut tree including antiatherogenic, anti-inflammatory, antioxidant, antimicrobial, antireproductive, CNS stimulant, hypoglycemic, anticarcinogenic, and hair growth promoting activities.

Mechanical Causes of Occupational Skin Disease

The skin is well adapted to cope with many types of trauma, but excessive friction and microtrauma can result in the formation of various dermatoses, and slowly increasing pressure or friction induces hyperkeratosis, lichenification and calluses.

The Super‐nettles

A widely distributed, well-defined, but not extensively studied group of higher plants comprises the stinging nettles. Because of their ability to inflict a painful sting on human skin contact, such

Direct release of the allergen tulipalin A from Alstroemeria cut flowers: a possible source of airborne contact dermatitis?

The allergen tulipalin A was collected by dynamic headspace technique from cut flowers of 2 Alstroemeria hybrids and quantified and identified by gas chromatography‐mass spectrometry (GC‐MS), and the amounts released into the air were correlated with the tulipalIn A and the total allergenic content in the plant tissue, respectively.

Investigation of Skin Irritancy of Crude Extracts of Ricinus communis L.

The present work was carried out to investigate the skin irritation effects of the crude extracts of leaves, roots, stem and seeds of Ricinus communis L. of family Euphorbiaceae on mammalian skin
