Brit rules throttle NZ honey claims

Britain’s advertising watchdog has ruled an ad promoting ma¯nuka honey as a treatment for coughs breached its code.

A complaint upheld by the United Kingdom Advertising Standards Authority said a newspaper ad for New Zealand-based Ma¯nuka Doctor should not have described the honey as a treatment for coughs and referred to its ‘‘anti-microbial properties’’.

Britain’s advertising code prohibits claims that state or imply a food can prevent, treat or cure human disease.

Karin Kos, chief executive of Apiculture New Zealand, said she thought the ruling would not be detrimental to New Zealand ma¯nuka honey sales in the UK but it might mean exporters needed to be smarter about marketing.

‘‘The food labelling rules are clear for honey that is produced as a food but as medical-grade honey it has gained a global reputation for support for reducing infection and it remains the most researched medical-grade honey in the world.’’

Ma¯nuka Doctor’s ad stated that in the UK’s ‘‘current health conscious society’’ there was ‘‘a simple form of self-treatment’’ for coughs that had the backing of government health watchdogs.

The ad told readers that ‘‘antibiotics alone will not prevent you getting a cough’’ but ‘‘honey can help with the symptoms’’, and ‘‘a 10g spoonful of honey significantly reduced the frequency and severity of coughs within a day’’.

Ma¯nuka Doctor’s British arm told the ASA that the ad had not claimed to ‘‘prevent, treat or cure a disease’’ because a cough was not a disease. It could be a symptom of some wider health conditions but not all coughs were linked to diseases. It also defended its description of ma¯nuka honey as anti-bacterial or anti-microbial, saying it simply referenced peer-reviewed research.

However, the ASA ruled that the ad had broken its rules around food advertising.

While Public Health England had recommended using honey as a first approach to relieving coughs, the code prohibited advertisers from stating or implying that a food prevented, treated or cured human disease in any circumstance.

Coughs were a symptom of a range of diseases ‘‘and in that context we considered the references to coughs would be understood as references to a symptom of Covid-19 in particular’’.

The authority also believed the anti-bacterial/microbial claim would be interpreted by consumers as able to kill micro-organisms ‘‘and therefore could both prevent those who consumed the products from contracting diseases caused by such micro-organisms, and treat or cure diseases caused by such microorganisms’’.

The authority said that because of the ban on food claims, it did not assess the evidence submitted to substantiate the ad’s claims.

The ASA instructed Ma¯nuka Doctor to remove claims to prevent, treat or cure human disease from its advertising.

Kos said there had been some interesting international studies from reputable organisations on honey and colds recently.

‘‘The first is from Oxford University which found that honey is better than usual care for relieving the symptoms of upper respiratory tract symptoms, especially coughs,’’ she said.

Another found that honey was better than nothing for childhood coughs but said there was no strong evidence for or against its use.

Kos said it was ‘‘no less effective than some pharmaceuticals indicated for the same purpose’’.
