Synopsis The miasms are causes of chronic diseases, and Psora itself is said to be responsible for seven eighth of diseases of mankind. So a deeper study of this giant miasm has been a need of the hour and this required a scientific analysis and a wider approach to view this factor. The author here, in his last chapter of the revised edition has given some winder approach after a deep study which may be appreciated by the enlightened homeopathic fraternity and people in general can be able to better benefit by the theory which so far remained in confusion for so many reasons.
