Thankyou so much for the information. I forgot to mention the base was black tea. Also, I realized that I think I was getting a double dose of everything because my husband brews his own mixture with black tea and then adds the store bought powder chai. Do you think it's a problem and something that could lead to cancer? The research I've tried to do doesn't look very conclusive. I'm not taking the double dose anymore, but my husband still is.
