Basically the EU regulations state that you must have the following on the label of a herbal remedy:
"Traditional herbal medicinal product for use in [insert baseless medical claim here] exclusively based upon long-standing use."
And you also get a lovely little kitemark to show that the MHRA has approved your drug:
They might be broadly safe and manufactured to certain minimum standards but the MHRA refuse to have any requirement to mention on the label that there isn't actually any evidence that this or that herbal remedy can do what the label claims, or even to mention that the evidence shows that it doesn't work at all. And then they boast about how:
"The growth of the THR scheme means that consumers will have access to a wide choice of over-the-counter herbal medicines made to assured standards.This government (and the last one) and the MHRA think you're stupid. They don't want you to know that these herbal drugs don't work because then you might not buy them. And that would upset their friends in the multibillion pound herbal supplement industry. Because ensuring a 'lively and competitive' market in useless drugs is more important than having a real informed choice. It's just the same story at home as selling useless dowsing rods as explosive detectors abroad.
"The current signs are that the market will be lively and competitive. The key difference for consumers is that in future they will be in the driving seat and able to make an informed choice when they wish to use these medicines."
