Bill Sardi is half right. In most European Countries a herbal can be sold both as a prescription AND and as an over the counter dietary supplement in supermarkets and pharmacies.
If this seems confusing, having both a prescription and a dietary supplement for the same herbal, its similar to the situation in the US over fish oil.
One company in the US has produced a prescription fish oil drug(
) which has been approved by the FDA after trials proving it lowers triglycerides and is prescribed by doctors(at an outrageous cost). At the same time fish oil is sold in health shops at 10% of the price.
This WHO list shows what individual European countries do with herbals both prescription and over the counter. This is given in the last paragraph of each countries report. In some countries they are allowed to claim that they are effective for individual complaints, something that seems anathema to the FDA in the US.

The EU is at the moment trying to rationalise all these different countries attitudes to herbals under Codex and cut down the number of approved herbals and their availability.
