I'm not sure about using potentised Staph as an application - I have not known it to have been used that way. However, if you have a 6x or lower, I can't see that there would be any harm in trying a pill, crushed and dissolved in the rinse water. Please report back as to the result...it would be useful to know if it does work, and it would be much cheaper than using a bottle of tincture each time.
