Of those 3 almond is most likely to cause a reaction. With herbs, it could be any one of them. Try eliminating anything that could be suspect until it goes away and add them back in, one every 4 or 5 days. When you add the allergen back in, you’ll know. Could be more than one and just because you were fine with something 3 months ago doesnt mean you will be now. When you have had the infection under control for a while and you havent had exposure to the allergen for 6 months, theres a good chance you’ll be able to have it again.
