During this corona year I have advised some patients to take arsenicum album as homeopthy for
symptoms which fit in the picture of arsenicum alb.

The main symptoms I have seen to make me think about arsenicum alb were:
BURNING FEELINGS , ANXIETY AND RESTLESSNESS, SHORTNESS OF BREATH, diarrhea
These symptom were sometimes also seen in patients with negative CORONA[tests], but especially after having Corona.

Below I will mention / copy some important symptoms of arsenicum album.
Extreme anxiety, often with great restlessness, moves from room to room, anxious about health, fear for cancer, panic attacks, especially after midnight, always worrying about health, needs constant reassurance from their doctor and saves everything [“clollectors”], compulsive -need to be always in control,
sudden exhaustion which may alternate with restless
Needs heat, very chilly
Often feeling of burning: burning headaches, burning eyes ,burning stomach[gastritis], burning esophagus

In the beginning of the epidemic some homeopaths have advised Arsenicum as the main prevention /treatment for corona.

Homeopathic medinas never expires. If there is written an expiration date on the bottle then this is for “commercial” purposes.
You can buy in Israel [or order online] Arsenicum albom as D30 or C30 [in the USA often marked as X30]in globuli [glulot]form.

For children Ars albcan be useful for [summer] diarrhea when diarrhea and heavy vomiting go together,

May also be tried for wheezing/asthma especially when this happens in the middle of the night. Sucking one simple globule maybe enough.
Still available in Europe but the EU is doing everything to get homeopathy banned.

I still strongly advise to continue with Portulaca and Echinacea 2x per day 30 drops.
