This is shocking but not surprising in the light of what Hahnemann wrote in Chronic Diseases. He said there were three main errors a prescriber can fall into:
1. too large doses
2. wrong remedy
3. not waiting long enough

Ref too large doses, he said he on occasion had trouble when using a dose of 4-6 poppyseed granules of 6c because it was not a small enough dose.
[CD p120 footnote]
Ref not waiting long enough, he writes CD p126 that immediate repetition is only permitted by a practiced observer under certain circumstances.

It is problematic that the unsuspecting public has access to homoeopathic remedies, on the other hand if supply were to be restricted you can be sure that it would be restricted to the wrong hands.

Hahnemann wrote that homoeopaths should follow him EXACTLY if they were to cure the sick. What hope has the untrained public of being able to do that? Especially when the doses widely available in the UK from Ainsworths, Boots, Nelsons etc are 6c's promoted as safe to take, with dosage instructions on the bottles, take 3tabs 3 times a day. EXACTLY OPPOSITE to Hahnemann's advice and warnings.
