Joan;
Gosh I hope not !
I made Lemon Balm Tea (from my garden) and drank it all summer. I dont recall It specifically triggering any symptoms... I know it has a calming effect and also  is a powerful antioxidant. I read up on it online, cuz I wasnt sure what to do with it at first. Mine got frostbite before I could save some for winter. (Also known as Sweet Melissa). I hope its not a degranulater- I used it in dressing too. I use grapeseed oil or olive oil with fresh lemon/lemony herbs because vinegar is a degranulater.
Hope this helps,
lori

I do fine with night time teas and stress teas and they have lemon balm. I can do licorice tea too, but none with cinnamon, cloves, etc. I also make my own ginger lemon tea and it's awesome.
