Homoeopathy to the Rescue in the Mentally Retarded Child

` Calc / Sil / Phos.

Dr Sosi Roy a psychiatrist originally, who later learned Homoeopathy is doing very good work with sub-normal children since 1934 when he got what he claims a Clarion Call.

He was greatly influenced by Prof Van Barnard of the Rudolf Science Society in Bornach, Germany. The approach therapy is given using music, colours, paintings, sketching and a peculiar form of dance called Eurethnoy for improving their speech and motor co-ordination. The students of a similar IQ also live together with a teacher with whom they develop a rapport.

He has grouped the children in Calcarea, Silica, and Phosphorus groups to remove the miasmatic blocks.

Calcarea - children with delayed milestones, defective intelligence and difficulty for mathematical calculation.

Silica - Children who are stubborn.

Phosphorus - Cretin children who are easily amenable. 

Treatment 
He claims that a combination of Homoeopathy and other therapies pay dividends in treating these burden to their parents.
