Is a combination of our favourite herbs Turmeric, Schisandra, Withania and Rhodiola. The curcuminoids in turmeric give this product a distinctive golden colour. CORT RX is as good as gold. Your friends may have told you about this combination and suggested you try it. That is a good friend. Do your own research and see what people are saying about these herbs and you will see it is the same thing people have been saying for generations about the use of these herbs in soups, teas and broths.
