no problem, I know how disappointing it can be to get no answer to one's post...I just happened to check out this forum.
I have been drinking home made kombucha tea for many years and love it (I make it with organic green and white tea from mountainroseherbs). I find it helps me with my general state of health. Some people also claim that kombucha makes their grey hair turn colored again. I can't make this claim as my hair has gradually been turning more and more salt and pepper.
I usually reduce the price of my teas at mountainroseherbs even further by buying 5 or more pds.,one can mix and match herbs.
If foti helps you to get rid of gray hair, I'd love it if you would let me know!
