Here I woud like to describe just a few MAOR CARACTERISTICS of this remedy

Many fears : diseases, cancer ,poverty, death

Anxiety about health [clinging to their doctor], needs company, out of fear

Extremely restless

Very chilly, craves for heat

Often symptoms start or worsen after midnight [1-3 in the morning]

There are many more symptoms but is the ones described above are dominating then there is a fair chance that the patient may react rapidly on Arsenicum

An Indian homeopathic doctor claims that iif these cases one may see a rapid improvement of the symptoms: fear.r, anxiety, restlessness, and chilliness will be less within half an hour! This is the power of homeopathy, if the remedy is right!
