A national campaign against homeopathic remedies being in sold in Boots stores was brought to Haverfordwest on Saturday.

One woman from Johnston took a lonely but determined stance against the so-called alternative remedies, joining a mass ‘overdose’ of homeopathic tablets, to prove that they have no effect.

Alice Sheppard swallowed a whole vial of homeopathic arnica as part of the Ten 23 demonstration which included protests in Liverpool, Manchester, Glasgow, London, Leicester, Edinburgh and Birmingham.

Merseyside Skeptics Society (MSS), which organised the events, has asked Boots to stop selling the remedies, which they call ‘scientifically absurd’.

Alice, who thinks she may have taken part in the only Welsh event, said: “Taking all this arnica could cause internal bleeding and gastro-enteritis but I am not worried, I believe it’s not going to work.

“I do think people shouldn’t be deluded into taking homeopathic remedies. They only have a placebo effect, if you have something seriously wrong, don’t delay going to the doctors.”

Alice did not suffer any side effects in the days following her ‘overdose’.

Homeopathy is described as a system that uses highly diluted substances to trigger the body to heal itself but critics argue there is no evidence they work.

Boots professional standards director, Paul Bennett, said the company follows advice from the Royal Pharmaceutical Society of Great Britain on the correct selling of complementary medicines.

He said: “Boots UK is committed to providing our customers with a wide range of healthcare products to suit their individual needs. We know that many people believe in the benefits of complementary medicines and we aim to offer the products we know our customers want.

“We would support the call for scientific research and evidence gathering on the efficacy of homeopathic medicines.

“This would help our patients and customers make informed choices about using homeopathic medicines.”
