@Al, Thank you for asking. The potent substance in ginseng, ginsenosides, reacts with the gallic acids in tea in the intestine when the two are ingested together. They become various particles that are not absorbable. This way both the tea and the ginseng are wasted. It is not understood yet whether these particles are harmful or not.
I have never liked or recommended those so-called ginseng oolong products. I actually have always told people to avoid them.
@Betty, I love a hot cup of sweet milk before bed from time to time but I have always wanted to avoid white sugar. That led me to study the nature of real raw sugar and found that it is an entirely different thing from white sugar! It has become one of my favourite sweetener since.
