Machaerium scleroxylon) in a hobbyist handling the wood. Plants reported to cause erythema multiformelike eruption include poison ivy (Toxicodendron) (Schwartz and Downham 1981 Mallory et al. 1982), primula Primula obconica) (Hjorth 1966) and mug-wort (Artemesia vulgaris) (Kurz and Rapaport 1979). Mallory et al. (1982) reported urticarial eruptions with black deposits on the skin of four patients with Toxidocendron radicans dermatitis. Urticaria, erythema multiforme-like eruptions, in a patient from Rhus dermatitis was reported by Schwartz and Down-ham (1981). They recommended that patients with such reactions should be screened for systemic involvement as previous reports have shown that nephritis can be an associated feature (Meneghini and AngeUni 1981 Fisher 1986).

Ginkgolic acids are urushiol type alkylphenols, related to compounds in poison ivy Rhus toxicodendron), and are associated with contact allergic responses, especially dermatitis. Ginkgolic acids are found in relatively high concentrations in ginkgo seed coats and in lower concentrations in ginkgo leaf (Blumenthal 1997).

Allergic contact dermatitis occurs most commonly from nickel-containing objects, plants (such as Rhus)y rubber, adhesives, or dyes in athletic tape, gear, or running shoes, and topical medicaments. Reactions are induced or elicited by the athlete s perspiration, which leaches the chemical allergens from their gear (Cronin 1980). Table 6 lists common contact allergens in the athlete and their recommended patch-test concentrations (Marks and DeLeo 1997). 

The Rhus plants, which include poison ivy, oak, and sumac, and contain the allergen urushiol, are the most common cause of allergic contact dermatitis in North America, affecting 50% or more of the population (Bergfeld and Elston 1994 Lowell 1996). A vast array of plants, including primrose and Compositae, cause contact dermatitis, airborne dermatitis, contact urticaria, and phytodermatitis, and are a potential threat to athletes participating in outdoor sports.
