Hi. 24 wCF
I have heard of people taking silver suppliments. I take sulfer to help reduce the inflamation in my joints and muscles.
Aloe Vera is a wonderful healing agent and unless your little sister is allergic to it, I think it is a great idea
As for the silver. I can't say either way. As long as your little sister goes to her check ups and all her blood work is good, then it shouldn't be doing her any harm
and , as we all hope, doing something to help keep her healthy.
