Got a bee sting? Try Apis (30C or 200C (200C is a little bit stronger than 30C)). AND GO TO THE HOSPITAL if you are worried!
Got a peanut reaction (synthetic/chemical)? Try Carbolic Acid (30C or 200C). AND GO TO THE HOSPITAL if you are worried!
If anaphylaxis is the issue, try either Poumon-Histamine or Gentiana lutea (200C) AND GO TO THE HOSPITAL!!! You may find that you do not need treatment once you get there, but don’t take the risk – homeopathy may not be for everyone.
