Arsenicum is often indicated in the treatment of anxiety when accompanied by marked fear, restlessness and irritability. The central theme of Arsenicum is a feeling of being too weak to survive a world that is both chaotic and threatening. In this context, Arsenicum types feel overwhelmed with vulnerability and have a tendency to lean heavily on others for support, which can lead to overbearing dependency. Other characteristic symptoms include fastidiousness, a preoccupation with death and dying, and lots of fears that include cancer, disease, robbers and poverty.
