Hello. Thank you for asking at HCM. I went through your history. I would like to know more about your problem like - Did you have loss of voice or altered voice? Did you have wheezing? Did you have anyone/more of itching, nausea, vomiting, fainting, collapse, skin rash, swelling of face/lips? Do you have any other allergies/asthma? Did you use the same brand of honey every time or they were different? Do you have similar complaints every time you take grapes or sometimes you can eat grapes without any problem? However, from your given history, I would like to make you following suggestions: 1. Honey contains many pollen proteins. Fresh fruits like grapes are also known to cause allergies. 2. If you have had any of symptoms like wheezing, collapse, fainting, loss of voice, choking, impending doom, etc it is highly recommended that you should consult an Allergy specialist who will ask your symptoms in detail and may suggest you allergy testing. As these symptoms can point to anaphylaxis (a form of severe allergy). If you have any of above mentioned symptoms, I would suggest you not to attempt taking honey or grapes before confirming your diagnosis. Hope above answer will be helpful to you. Should you have any further query, please feel free to ask at HCM. Wish you the best of the health. Thank you & Regards.
