Herbal Medicines

Lord Taverne Excerpts

Wednesday 24th April 2013 Grand Committee

[Lord Taverne]

My Lords, I am grateful to the noble Lord, Lord Pearson, for raising this Question. Not entirely unusually, I do not altogether agree with everything that he has said. My view is that the Government should not establish a register for unlicensed herbal medicines. To quote that indefatigable battler against quack science, Professor David Colquhoun, herbal medicine means,

“giving patients an unknown dose of an ill-defined drug, of unknown effectiveness and unknown safety”.

My objection is that licensing will confer on practitioners supplying these medicines a spurious respectability and credibility that can do great harm.

Every time I raise the lack of evidence for alternative medicine in this House, someone gets up, as the noble Lord, Lord Pearson, has now done, and says, “But I was cured” by whatever it is—Chinese herbs or homeopathy. On the last occasion I raised it in the House, the noble Baroness, Lady Corston, praised homeopathy and said that she hoped that my well known views, which she seemed to suggest were somewhat eccentric, would be ignored by the Secretary of State for Health. They are not entirely eccentric views; they are the views of the scientific consensus.

The noble Lord, Lord Rees, spoke about homeopathy at a time when he was still president of the Royal Society. He said that if homeopathy worked other than as a placebo all the laws of science would have to be repealed. There is not, to my knowledge, a single fellow of the Royal Society who supports either homeopathy or Chinese herbal medicine. The most detailed, careful, scientific, blind trials have confirmed that view. Only recently, the Chief Medical Officer, Dame Sally Davies, said she was perpetually surprised that the National Health Service still funds homeopathy. I recommend to those who advocate alternative medicine the book Trick or Treatment? by Professor Ernst and Simon Singh. It is extremely well researched and a very objective treatment, which does acknowledge when there may occasionally be some possible benefit, but on the whole their views and conclusions are quite plain. There are many reasons why many people feel better after treatment—often because placebos do work, whether after taking a homeopathic dose or treatment with herbal medicine. Private practitioners of alternative medicine often have more time for patients and may be good at tender loving care, which is a very important feature of good medical care. Often, people get better anyway.

Anecdote is not scientific evidence. People say, “Well, does it matter if treatment works only as a placebo?”. It does matter. Faith healing sometimes works, if people believe sufficiently strongly. In parts of the world, so does witchcraft. However, it really matters if people who are seriously ill do not take scientifically proved treatment, or if pharmacists, for example, prescribe homeopathic pills for malaria. Dr Wakefield was believed because many mothers reported that their children showed signs of autism after taking MMR. I remember a “Panorama” programme which interviewed several parents who told how this happened to their children. The programme was extremely sympathetic to Dr Wakefield’s views, and stressed how kind Dr Wakefield listened so carefully to these parents, but completely ignored the overwhelming scientific evidence that there was no established link between MMR and autism. In fact, the anti-vaccination campaign was organised by a group of people who were strong believers in alternative medicine. Today, we see the consequences in Wales.

Quack medicine is not harmless. We should not make it respectable by statutory registration, which suggests that it is not only respectable but officially licensed. Although the noble Lord, Lord Pearson, as usual, put forward his views very charmingly, I know of no one in this House who puts forward misleading arguments more charmingly.

--- Later in debate ---

[Baroness Northover]

Various noble Lords have made that point.

My noble friend Lord Colwyn asked whether the Government have in fact dropped the commitment to regulate. The Government recognise that there is a body of evidence about the public health risks associated with herbal medicines. It is important that the department does not proceed with the statutory regulation of any group, including herbal practitioners, unless we are sure that this will provide the necessary safeguards for patients. In other words, it is being looked at very carefully—whether the balance of regulation helps or hinders. Noble Lords have heard various views expressed.

[Lord Taverne]

Will my noble friend answer one question? Is registration supported by the Chief Medical Officer?

[Baroness Northover]

I am afraid that I cannot answer that very simple question. I may be inspired to do so shortly, but in the mean time I should say that this is a more complex area than that. Although I will be happy to come back to my noble friend, I think that there are a number of wider issues to look at.
