I don't know much about herbs but I do know that I have had excellent luck with chorella and liquid bentonite clay. Chorella is a heavy metal chelator, Taken internally, liquid bentonite supports the intestinal system in the elimination of toxins. Liquid bentonite is inert which means it passes through the body undigested.
Bentonite clay is made up of a high number of tiny platelets, with negative electrical charges on their flat surfaces and positive charges on their edges.
When bentonite clay absorbs water and swells up, it is stretched open like a highly porous sponge. Toxins are drawn into these spaces through electrical attraction and bound. In fact, according to the Canadian Journal of Microbiology (2), bentonite clay can reportedly absorb pathogenic viruses, as well as herbicides and pesticides.
The bentonite is eventually eliminated from the body with the toxins bound to its multiple surfaces.
Here is info on chlorella.

I took the chlorella in the morning and the clay at night, I did it for 3 weeks and I definetly noticed I was less reactive to things after the cleanse. You know when your sick you will try just about anything that you think will help you feel better or get better. But I'm a leaker not a shocker so it's not as scarey for me to try stuff like this. You said your husband reacts to a lot of things so definetly ask your doctor first if it is safe. It was recommend to me by a naturopath and my chiropractor. I felt no side effects during the cleanse, I feel it was extremely gentle.
If your interested in what brands to use I can give recommendation on what I used.
