Yeah so I just started, Brother's girlfriend gave me a Scoby. I was wanting to use White Tea. However my White Tea that I have is mixed with Hibiscus, Lemon Grass, and Dried Pomegranate, and was wondering if these herbs are safe? I am turned off to using green/black tea due to the toxic levels of Fluoride in them. So was hoping to do a mix of black and white (mostly white). Will these herbs kill the scoby?
