Cashew allergy rash8/13/2023 ![]() Terry Rector writes for the Warren County Soil and Water Conservation District. Pruritic rash beginning 1-8 days (median 2) after cashew consumption and lasting 5-21 days (median 7) was reported by 29 persons rash occurred on: extremities-97, trunk-66, groin-45, axilla-34, buttocks-21. Now, for some itch-free plants, remember Arbor Day tree seedlings will be handed out Friday morning by the Warren County Soil and Water Conservation District at the USDA office on Sherman Avenue. So far I refuse to quit coffee but it might happen. The older I get the more good things to eat and drink I have to abandon because they cause nasal swelling, funkiness of the throat and other allergy symptoms. The full-strength stuff lasts too long.Īlthough rare, there are those among us who are sensitive enough to any minute level of urushiol that they have had rashes breakout after eating cashews or had itching of lips after eating mango.įor those unfortunate few, I say tell your doctor about it and life can still be good without cashews or mangos. I don’t know how many washings mangos get before display at the store, but peeling sends whatever oil might be left to the landfill or compost pile. The treatment for anaphylaxis is injectable epinephrine. Mitchell JC, Rook A, 1979, Botanical Dermatology, Plants and Plant products injurious to the skin, Greengrass, Vancouver.Again, the people doing the harvesting and handling of the fruit where grown are the ones who need and get protection from urushiol.

Garcia F, Moneo I, Fernandez B, Garcia-Menaya JM, Blanco J, Juste S, Gonzalo.These cross react to other members of the Anarcardaciae family including poison ivy, Toxicodendron succedaneum (Rhus tree) and mango. Fortunately allergy to cashew nut appears to be much less common than to other tree nuts. This appears to cross react with pistachio nuts. This potentially life-threatening condition is due to an allergic reaction to a very small molecular weight component of the kernel itself. ![]() This is quite different to the IgE-mediated immediate anaphylaxis to cashew nut. Most reactions appear to have only been dermatitis (although most needed treatment with high doses of oral steroids). There are a number of reports of allergic contact dermatitis following ingestion of cashew nut butter, a cashew nut pesto, and cashew nuts contaminated with cashew nut shell oil. ![]() Problem arise when children play with the raw shells, if improperly shelled cashew nuts are sold, or roasting is incomplete. Roasting the shell of the nut liberates irritating vapours, but if roasting is complete, all the allergens should be inactivated. There are two problems with cashew nuts, allergy to cashew nut shell oil and allergy to the nut itself. The cashew shell nut contains a brown oily juice, full of very potent allergens including cardanol, cardol and anacardic acid. Modified cashew shell nut oil has a number of industrial uses including an ingredient in ink, as an adhesive and in the manufacture of resin. ![]()
