  1. With reference to cerebral hypersensitivity, how would you estimate the effectiveness of treating patients suffering from Visual Snow with loganaceae?

  2. Your comparative study of 9 Medicines of LOGANIANACE is very good. Your notes helped our 23 members group to acquaint with the Medicines. Highly informative and properly analysed.
    Once again Thank you.

  3. Spigelia,palpitation of heart due to rheumatism worse morning worse lying down hand feet cold.Veratrum palpitation hand feet cold but better lying down skin pale plus forehead cool perspire.Heart is epicentre of any trouble PALPITATION cure is 50 percent cure.old age weak memory plus palpitation anacardium.students are advised to keep a copy print of article by P Klien homoeo world aug 1932 journal on heart palpitation.1930 to 1950 homeopathy was at peak then eclipsed due to many reasons one being modern homeopaths blended homeopathy with importance to symptoms disease wise.Hering proving notes and law of cure is writing on stone wall it does not change.

  4. curare blockage nervous stimuli neuronal-muscular synapse leads to flaccid muscles lack voluntary contraction produce condition like myasthenia gravis,suffocation chest weakness lung muscles,general hypothermia hypotension with tachycardia,numb paralytic deltoid,wrist hand feel weak,useful in senile debility and diabetic numb extremities,hair lose luster grow grey,tinnitus,bitter taste,flaccid muscles spoiled by gym excessive exercise.causticum esp for bladder control is better by humid climate,gelsimium influenza types.curare q do not use will make muscles lose tone.curare30 or 200 plus nux vom very low potency muscular tonics,rhus tox200 remove arthritic toxins,many homeopaths earn good money by these thee remedies as one feels active praises homeopathy,but they will not divulge name of remedy homeopathy still a trade secret pathy.
