Is arnica a clinical remidy which treats the symptoms as long as it is taken or is it a deep acting remidy that can remove a disease(neurogenic hypertension in my case) constitutionaly the drug picture matches about 40% to my symptoms . All tests like blood culture,ecg etc are normal.Currently my homeopath has put me on thuja ,sulphur,raowolfia,cactus,crategus,5 phos,staphysagaria. Previously he had started with plustila, anacardium,aconite,arsenic,kali this,nux vomica. Then on baryta mur for 14 days. I am Hypersensitive and overweight and also have some degree of white coat hypertension. My doctor told me that I have psoric and psycotic miasms. Unfortunately none of medication has worked so far. Now I feel worried and helpless just arnica with him.requesting for kind help from doctors regarding arnica or any other drug which may be discussed.thanks..
