Yikes! Hives!
Was it the liquid form of ficin latex?
The Alt Med Dr. was going to get the Rain Tree (?) (Rain forest) products to try for the parasites, he said they were mostly liquid. I'm sure I've seen someone on this forum that has used them. I think they are only available through practitioners (?) but it turned out to be a hassle for him.
It's not cheap, but have you tried the megadoses of CoQ10? That might be worth a try while you've got it on the fight. The lightly ozonated olive oil isn't being shipped during the summer, but L-Cysteine, Coq10 and coconut oil or castor oil would be worth a try too.
