I posted earlier that I was reading that peppermint tea can help with symptoms, but in checking into it, I learned that it can worsen acid reflux. So, if you have that, definitely do not try it. Most studies have been on the oil, not tea. I'm experimenting with tea for now. One article suggested that if you want to use the oil, which can be deadly if overused, you should consult your doctor. Heck, my doctors don't even know anything about COVID.
