The pragmatic regulation of herbal products

The pragmatic regulation of herbal products

I have a letter in the BMJ about pragmatism in relation to the regulation of herbs:

The risks to patients from unregulated herbal preparations means a scheme that reduces the risk of adulteration carries a public health benefit, even in the absence of known efficacy. Differing licensing requirements for prescribed drugs and herbal products do not reflect dual standards of evidence; a herbal product licence is an admission that the product has no proved efficacy.
