Hi Crazy2medic,
Welcome to our forum Crazy2medic!
Like Csmm suggested: have you or your wife had the time to go through the 'New to Lyme? ... Start here!' thread on top of the lyme forum? It is has a huge amount on information about different treatments, detoxing, symptom lists, useful links, etc.
I always took Cat's Claw (Samento) in tablet form, so the taste wouldn't bother me.
If she is taking the powder, maybe you can put it in capsules?
Samento is a very strong (but very efficient) herb. When starting it, slowly build up the dosage, be sure it stays comfortable to handle. I myself had to build it up over a month's period and then had to cut back again, then build up again.
Good luck!
MarieLS
