No. In fact, we've reason to believe they act similarly from a TCM perspective. Xiao Yao San, as you know, tonifies and moves Blood and moves Qi. Cyclosporine appears to tonify and move Blood. So my perception would be that, if any interaction is seen, it would be that the dog is able to be managed on a lower dose of cyclosporine than would ordinarily be expected.
Please let us know if that turns out to be the case.
