I found this on one book website when looking for info about the herbs:

What the EU has banned us from
According to the current EU legislation for herbs and herbal products, we may not provide more detailed information that could give us the impression of a health or healing effect of the herbs – even though those herbs have been used for hundreds of years and have helped millions of people. We are no longer allowed to mention even the effects of herbs proven by scientific research unless it is a drug registered by a pharmaceutical company.
