Kia ora Lyndall. Thank you for taking time to provide a review for our Kawakawa Decongestant Rub. We're pleased to hear it worked well for you but gave you a rash. Here is a list of ingredients (100% natural) - New Zealand Kōrari (Flax) Seed Oil, Beeswax, Macropiper Excelsum Kawakawa, Cinnamomum Camphora Camphor, Mentha Piperita Peppermint. You may recognise one of them which historically impacts your skin. Thank you again for your review. Natures Therapeutics.
