Silver Sol is a nano silver. We used the gel on my mother when she had an acute case of MRSA. The doctors were astonished it healed. We used the gel liberally, but it got the job done. She also was on antibiotics.

Great for more superficial stuff but doesn’t work on deep tissue infections like I’ve had. No topical formulation does. Silver taken orally is worthless.
