My 2 year old daughter has MRSA. She has already had 4 surgeries to drain them. I am currently making a Usnea infused oil or a salve. After a lot of research there’s not a lot of herbs you can use for staph or on young kids. Is there anything else I can add to my usnea salve to help her? Her little digestive system is so messed up from load of antibiotics from the docs and want to find a more holistic nature way to help her and hopefully avoid her next 5th surgery.
