If you rush out to buy medicine at the first hint of a sniffle or sore throat, new research from Which? could make you think twice.
Popular health remedies from high street chemists lack true evidence in curing common ailments and some include a huge amount of sugar, a study by the consumer group has found.%VIRTUAL-SkimlinksPromo%
Labels on health products promise all sorts of wonder cures, but the investigation found very few products have robust evidence to back up these claims.
Which? is concerned that consumers are being misled and urged companies to be honest about what these often expensive products can actually do, particularly when it comes to important issues like health.
Popular cough remedies such as Benylin Tickly Coughs and Benylin Chesty Coughs (both Non-Drowsy) and Covonia Herbal Mucus Cough Syrup were found to have 'no robust evidence' that they do what it says on the bottle.
Which? reports that Boots declined to send the evidence for its Cold and Flu Relief tablets, as did the manufacturer of Adios slimming pills and Benylin for cough medicines.
The consumer group concluded the study with a list of health products you do not need (below). It includes Seven Seas Jointcare Be Active tablets, which use the claim "Keep really active with this everyday plan to look after your joints."
While they were found to contain proven ingredients for protecting aging joints, the amounts are "well below effective levels."
Bach's Rescue Remedy Spray claims to help de-stress but experts highlighted research showing it to be no more or less effective than a placebo.
Similarly Bio-oil, which claims to improve the appearance of scars, was found to be no more effective than massaging with other moisturising lotions.
The investigation also found that certain remedies contain huge amounts of sugar, which can actually be detrimental to health. Benylin Tickly Cough for example, contains glycerol and liquid sugar as the active ingredients, in addition to other sugars.
Which? states that the content equals 1.5 teaspoons of sugar per 10ml dose. If an adult took this medicine at maximum dose for a week, it would be the equivalent of the sugar in five Mars bars.
The manufacturers of the products examined by Which? said that they all met the standards of the independent Medicines and Healthcare products Regulatory Agency (MHRA), which requires evidence to demonstrate they work.
However, the consumer group is calling on companies to be more transparent, so consumers can examine claims and make a truly informed decision.
In the meantime, avoid wasting money on potentially useless remedies by seeking advice from direct from pharmacists or your GP.
