my daughter, aged 28 drank a cup of organic green tea with natural flavors. It was labeled green/blueberry tea and the contents as green tea with natural flavors. Within five minutes, she was not able to breathe through her nose, her eyes swelled up and her throat became very tight. Gave her benadryl, which she was just able to swollow. It stopped the reaction and ten minutes later, she could still not breathe through her nose so I gave her a face mister with eucalyptus essential oils and the membranes started to recede to allow her to breathe through her nose. Is this anaphylactic shock?
