Hello everyone, I am new to this board. I am working with a homeopath. After working with lower potencies of Natrum Mur, with some good results (but they stopped working), my homeopath has increased the potency to the CM potency. I know that the CM potency is the highest. I just wonder why I need such a high potency. I do have depression, but it is not severe by any stretch. Is the CM potency given often for Nat. Mur? Do the symptoms have to be severe in order to give CM? Both 50M and 10M worked for a little while, then stopped. What happens if the CM potency worked for a little while, then stops working like the others...there isn't a higher potency to go to. I would assume then that I had the wrong remedy to begin with. Am I correct?
