Based on the tests carried out, some batches of the labeled-product Black Cohosh have found to contain Cimicifuga foetida which is not used in Western herbal medicine and whose safety has not been evaluated.
Not meeting the standard requirements means that the product does not meet the quality required and must be removed from the market, claims MHRA.
Medicines and Healthcare products Regulatory Agency medicines borderline section manager David Carter said the agency expects a product to list all the correct ingredients on the label.
"In this instance they were not fully listed and, therefore, the product does not meet the standards required for public use," Carter added.
"That is why we have told the company to recall the product from retailers and also to ensure that the recall is communicated to members of the public."
Based on the evidences, MHRA advised consumers to stop using the Black Cohosh Root capsules and return unused product to Viridian Nutrition or health food stores.
