It does lower blood pressure, so if you have low blood pressure this needs to be kept in mind until the adrenals are built back up. This will bring the blood pressure back to normal as low blood pressure is a symptom of poor adrenal function. And it is bitter, so it can be a problem if you do not have a gallbladder as the bitterness will stimulate a release of bile. Without a gallbladder this can lead to burning of the intestines and diarrhea. The tea can be diluted to get around this problem. Otherwise it will not adversely affect digestive issues. The bitterness will help with heartburn though.
