Although this snippet does not speak to exactly what I originally posted about, it does mention that Samento and quniolone Antibiotics are not identical.

I recalled something I'd read in herbalist Stephen Harrod Buhner's book "Healing Lyme" about the difference between Cat's Claw and quinolone Antibiotics i. I'll type what I read here in my 2005 paperback edition on page 102:
"The quinovic acid controversy: A rumor has spread that the quinovic acids in cat's claw are, at root, the same as quinolone Antibiotics . The rumors say that this is why cat's claw is effective against Lyme spirochetes. Concern has been generated by this untrue assertion because quinolone antibiotics, in some instances, can cause severe inflammationi in tendons. So, the word is that cat's claw can cause tendonitis, resulting in tissue destruction over time. This is all completely untrue. The quonovic acids in cat's claw are structurally different than quinolone antibiotics. Molecularly, they are not the same at all and they do not do the same things."
