Calcium sulphuricum
Calcium sulphuricum is a relatively unknown remedy.
Recently the picture has been developed further, but the details have not been added to the standard materia medicas yet. Especially Candegabe (1987) and Sankaran (1991, page 219) have done a lot to expand our knowledge of Calcium sulphuricum. What we see is a picture of aggressive and jealous children. Sankaran sees the key symptom as 'lamenting because she is not appreciated'. This belongs to a situation in which a child feels himself unappreciated. The other children get more love and attention. The reaction to such a situation can vary between timidity and jealousy and aggression.
