Early experimentation with Anacardium occidentale and cardols present in Australian species indicated that susceptibility to cardols was more prevalent than to anacardic acids or cardanols. However, more recent studies with Ginkgo biloba have found that anacardic acids were good sensitisers, while cardanols failed to induce allergic contact dermatitis [297].

Ginkgo leaf contains ginkgolic acids (urushiol type alkylphenols), compounds that are related to those found in poison ivy Toxicodendron radicans) and associated with contact allergies, especially dermatitis. Ginkgolic acids are found in relatively high concentrations in ginkgo seed coats and in low concentrations in the leaf (Blumenthal 1997). 

Contact with ginkgo fruit pulp has been associated with contact dermatitis in a number of individuals (Nakamura 1985 Tomb et al. 1988).
