Trouble with specific herbs when cooking?

I made a compound butter with some herbs from my garden. I froze it in small containers and have been using it on all sorts of things for the last few months. I did notice that when I put it on plain noodles, I would have a bad night. I thought it might be too much butter, since I was a bit heavy handed with it. But the more I use it, the more I am realizing that I think it is the herbs that are bothering me. I had some on rice yesterday. Rice is one of the 2 or 3 safe food I can eat right now. I always put butter on my rice, but I was miserable afterward and for the rest of the day. I really don't want to give up all flavor, but if I could figure out which herb or combo might be the likely suspect, maybe I can make a new batch and still have some tasty food.

Here's what I put in:

Parsley
Scallion
Thyme
Mint
Basil
Oregano

Anyone know if any of those are likely to cause trouble? or is it just the fact that I put something green in my mouth?

For me its parsly....when we eat out I have to make sure that I ask for that to not be on my plate.

Well I'll just add to the confusion....for me the mint would be the worst thing on the list.  For some reason mint or even mint extract bothers me.  Thyme is questionable as I have it so rarely, but I know I had an issue the last time I had it....might be coincidence

When I am trying to reintroduce greens into my life, I puree them first, one or two at a time, and try them that way.

e.g. puree parsley; use it as a pasta topping.

I find that parsley can be pretty scratchy on the tum at the best of times, and is best pureed anyway.

If you're sensitive to onions, scallions could be the culprit?

This is what is so confusing about this dang disease. None of these used to bother me (except the mint, which I never really used before). All of the herbs were very finely chopped and I have cooked with them for years. I guess I will try either each one by itself or just eat very plain food. Right now everything except rice and fish seems to bother me and even those aren't always safe........
