YesI have given Thios to a patient with internal scarring after an accident and bone graft etc. When the surgeons went in again to cut out the scarring they thought was causing the limb to be so stiff there wasn't any, it had gone ( 3-4 months Thios 6). The problem was no tendon and bones going the wrong way.

Also used it on myself externally for scar from acne. They did go but might of anyway. I dissolve a pillule in water and dabbed it on. Warning, the liquid starts fermenting after a few days!!!

It is also well known for shrinking fibroids.
