The prescription for this Remedy is quite simple – it is for those who feel an irrational and disproportionate fear for the safety of those dear to them, a fear that makes their lives uneasy and at the same time is a heavy burden for the ‘claimants’. It overstrains and exhausts relationships. In their positive aspect, however, these people have exceptional self-possession and physical and psychic stability in strenuous and unexpected circumstances.
For those who find it difficult not to be anxious for other people. ... frequently anticipating that some unfortunate thing may happen to them.
