PISTACHIO AND CASHEW ALLERGY SKIN

These allergic reactions include skin lesions (urticaria and angioedema), gastrointestinal symptoms (abdominal pain and vomiting) and even anaphylaxis. Oral ingestion or direct contact with skin/mucosa are the two routes of cashew nut exposure causing allergic reactions in individuals. Cashews are salt-loving species, that prefer growing in warm and humid climate with optimum temperature ranging from 22 to 32℃. Cashew nuts are consumed, either in raw or roasted form, as snacks or used in butter, sweets, confectionery items, chocolates, and ice-creams. This hard shell consists of toxic oily fluid, containing allergenic phenolic molecules inside it, however the kernels/nuts are protected from this toxic oil by a film. The unique features of this tree are its fruits that consists of a pseudofruit (cashew apple), which develops as a yellowish-red swollen peduncle and a true fruit, that evolves enclosing a kidney-shaped nut inside a double hard shell, growing at the end of the apple. It is a very versalile crop that grows commercially in many parts of the world. Cashew is a tropical, evergreen tree that belongs to Anacardiaceae family.
