Homoeopathic materia medica of sarcodes

The study of 'sarcodes' is one of the greyest areas of homeopathic materia medica, which has not yet been thoroughly explored. Most of the sarcodes are not proved as per the standard guidelines of Dr. Hahnemann nor have the majority of them been clinically verified. On scrutiny of the available literature on sarcodes, a lot of differences and contradictions are witnessed which lead to confusion in the minds of the readers, particularly in respect to their sources, preparation, clinical applicability, effective potencies & doses etc.. There is no clarity whether sarcodes should be earmarked as a separate class of the 'animal kingdom'. Moreover the signs and symptoms of each sarcode are not documented uniformly in different homoeopathic Materia Medicas, which naturally confounds the readers.
