Simone,

For what it's worth, In Sankaran's THE SOUL OF REMEDIES, "The main feeling of Hyoscyamus is that of being suddenly let down, disappointed, betrayed and deserted by the person on whom one is completely dependent. ... The situation of Hyoscyamus is that of a man deeply in love with his wife who is having an extramarital affair. ...
Yet another case...of a woman who said that she was very dependent on her husband and lived with the constant fear that he might betray her. ...
Rubrics: ... Delusion, wife (husband) faithless."
