In most cases natr antidotes carc, but not always, individualization rules, each case must be somewhat monitored, and you use the remedy in each case that fits the present picture best, at any given time.
That natr mur is a antidote to carc, is merely A MARK, on a little notepad that you have, reminding you that in most cases it is this who works, but do not thrust blindly in that, that can be a fatal mistake to do, indivvidualize, ALWAYS.
Do not fool yourself to think that it is a easy way out, that a mental picture you see, have given you the remedy, in most cases it gives you a distorted vision of the patient, you need to know science theorie, it will tell you of this problematic, so always repertorize a picture, and use spontane bodysymptomes, the body dont lie, and the spontane symptomes the body present, is often clear cut, and is not interpreted by you or the patient.
Saying Aou.... when you cut your finger is sutch a spontane, clear symptome.
Begin to interpret that, and you end up looking for a rubric that dont exist, as, a knife, cause to..that is trying to treat the knife insted of the patient....if you qiute can follow what i try to tell.
