I have just eaten a head of Organic romaine lettuce and my mouth gets totally dry and feels like swelling, it feels weird, hard to describe exactly.. I have experienced this some times now after i bagan to eat the greens for themselves and not in smoothies. It happens with most green after i have been chewing/eaten a good portion (100-200 g). Is it something that i should just ignore or? Hope you Can help me Doug. Thank you!
