When your cycle is being affected by other factors randomly, the pill isn't as stable in your system, thereby decreasing effectiveness. (anybody with a thyroid condition should never eat grapefruit too, btw, really messes the thyroid gland up)
There are over the counter herbs and supplements that can make them less effective, so always check with a doctor or look things up online extensively before taking anything like that. I've never heard of basic teas affecting anything pill/endocrine system wise. Green, Black, White, and regular herbal teas should all be fine. There are special "medicinal" herbal teas that can mess things up, but you'd have to go to a specialty store to get them, unlike what you'll find on the grocery shelf, etc.
This just goes to show that anything in excess is bad for the health. I just want to ask. Is it the same case if you are going to take natural grapefruit? I do not think so, right? Even those who have diabetes can work with the sugar from freshly-picked fruit, right?
