MHRA Recall Black Cohosh Product

MHRA, the UK regulator of medicinal products, has called for a voluntary withdrawal of black cohosh products due to potential contamination.

Contrary to the MHRA report the suspected contaminant Cimicifuga foetida has actually been researched and is known to possess anti-viral, antidepressant and anti-tumour activity, and has not shown any noted adverse reactions:

Cimicifuga racemosa (now known as Actaea racemosa), according to the above report has been associated with hepatotoxic reactions despite research showing the opposite:

Contamination is certainly not desirable however and I would urge members of the public to purchase licensed herbal products from reliable suppliers, or visit a herbalist...
