hi linda : I have the same problem with cortisol ,it is on the high side , I was able to lower it with ginseng which is an adaptagenic herb ,but also found out at the same time that there is a reason that it is so high, the high cortisol is trying to compensate for other hormones that are out of whack , for me it is testosterone , when I raised my testosterone with herbs according to my blood work , then the cortisol level came down , you probably have high cholesterol levels too , cholesterol is the very first ingredient in creating other hormones , that is why most people that are truly mercury poisoned have high cholesterol levels or very low levels

If hormones are out of whack then the body tries to compensate in other ways , the key is to find out what hormones are out of balance and try to balance them as much as you can with herbs or through supplimentation while you get the mercury out of you body , It made a big difference on how I feel through mercury detox
