One of the coolest things about remedies is their saftey as Allision states. Many of us have found that with a 30 potency repetions are not necessary when it's the correct remedy and there are no antodoting behaviors ( coffee or mint). If you wish to repeat often even lower potencies, 6 or 12 are probably preferable. Just off the subject a little. I had a client with very stubborn nipple yeast, seemed to be in her ducts as well. She chose to use a homeopathic remedy, we considered several after a complete case was taken and chose sulphur 200c. She is clearing up nicely and after only 24 hours. Rita Ippolito Warren
