I had an interesting experience with raw garlic yesterday and am wondering if anyone has an idea. I chopped up garlic and ate a couple of small cloves with heirloom tomatoes for lunch, not something I normally do (raw garlic, that is). About 10-15 minutes later, I felt very light headed and a little dizzy, like mild vertigo. It lasted for about 5 hours and I was fine after that. Do you think it was my blood pressure plummeting from eating raw garlic or a high histamine response? Thanks for your thoughts. Am thinking about doing a before and after blood pressure reading next time I eat raw garlic, but didn't think about it in time.
