N:The best allergic reaction and my friend has it for over the counter reaction was a magnesium chloride 1/8 teaspoon mixed in 1/2 glass of water. The response in detoxification is quite fast and within minutes. In event that this can't be located, any magnesium citrate (WITHOUT ANY CALCIUM) will work.
The second one that might help is 5 drops of 3% H2O2 food grade in 1/2 glass of water taken.
The third one is activated charcoal as per packaged instructions.
Improvement with above two should be relatively quick within minutes.
This is first aid only and longer term remedies can be considered later, such as 1/2 teaspoon of baking soda with 3-5 drops of 3% H2O2 food grade in 1/2 glass of water will reduce the rest of the other toxins.
The last remedy may either be apple cider vinegar and bakng soda and/or vitamin C sodium ascorbate, but that's usually not required as the other remedy should take care of most of it already.
