Be very careful with any herbals.
I am (was) addicted to licorice tea pre BC.
Out of curiosity I asked my Oncologist if I could still have, she consulted with the pharmacist, and it was a big fat NO.
One of the concerns was it messes with your potassium levels which in turn has a domino affect on the rest of your readings which in turn means a possible mess up of your treatments.
All of read through this forum gives me the impression we are all stuck with this horrible affliction.
But if you find something that gets the green light by your Oncologist and Pharmacist please, please let us know.
Good luck!!!
