I have had the same issue ... there is something in the tea that does not agree with you . give it a cupple days and see or if it bothers you that much get it checked. mine went a way in a cupple days .
It could be an allergy. Many herbal teas contain chamomille which is very similar to ragweed. If you have ragweed allergy, you could be cross reacting with the chamomille.
many years ago my parents brought back some apple tea from Greece - no idea what was in it that i reacted to as the ingredients were in Greek!! my parents raved about the stuff so i had a cup with them before going out to meet friends - i did not even make it to the bus stop! i ended up sat on a wall struggling for breath and in pain outside a house 5 doors away from our house - i rang my mum on my mobile in a blind panic and she had to come and get me!! by the time she got to me i was vomiting and had the most violent stomach cramps!! i was a mess!! mum chucked the tea away!
--The real answer (not medical as it is usually biased) is that it is an incorrect response by your immune system.
-- Why? Well it seems that the most likely explanation is that, there's an Energy imbalance affecting how your immune system responds.
--What to do? Avoid the offending substance or clear the Energy imbalance. Then the immune system will respond normally again. And the allergies disappear like magic
--How? Read my reply to mariyamary (Hand Allergy) for the procedure Dec.27.
That procedure should work fast for treatment and/or relief of allergies, sensitivities and reactions.
Blessings to All
