I just brought it from t2. Drank 3 cups a day since Friday. I asked my acupuncturist to make sure it was ok to drink. She said only to drink it until day before transfer. She also recommended I drink ginger tea to try stay warm. I just added some ginger to my raspberry leaf tea. Your lining was fine last month though before your transfer so it may not help you hun. I was also taking herbs from my acupuncturist. I stopped taking them yesterday too & didn't mention anything to my fs clinic about it.
