Nightshade family

Vast group of vegetables. As with all cross reactivity, allergy is not automatic but being allergic to one or more increases the chance you will be allergic to another.

  • Tomato – but see also salicylate intolerance
  • Aubergine – can contain histamine like chemicals!
  • Bell pepper (capsicum) – from which you get the spice paprika, often used in other things eg salami, pepperoni
  • Chilli pepper
  • Potato (but not sweet potato). Raw potato is sometimes the problem (contact, obviously) rather than cooked.
