Tea with asian ginseng. Should not be used for more than 2 wks at a time without a 1 or 2 week break. I just use it every other day. That would be tommorow. Ginseng stimulates the adrenal glands, perhaps it overworks them if use continueously, but its different with the elderly. Some how, it was not in the herb book I read. Asian ginseng is the strong shit not like American ginseng.
