Fisherman's Friend

Fisherman's Friend is a brand of strong menthol lozenges produced by the Lofthouse company in Fleetwood, Lancashire, England.

Fisherman's Friend was originally developed by pharmacist James Lofthouse in 1865 to relieve various respiratory problems suffered by fishermen working in the extreme conditions of the Northern deep-sea fishing grounds. Though he developed it as an extremely strong liquid remedy containing menthol and eucalyptus oil, Lofthouse later made the liquid into small lozenges which were easier to transport and administer. According to the manufacturer, the fishermen began to refer to the lozenges as "friends", hence the name. British Prime Minister Margaret Thatcher is said to have used the product when her throat became strained from public speaking.

The lozenges are relatively unchanged since their creation. The original paper packets later became foil-lined and packaged in a cardboard carton. In some locales the standard 25 gram paper-foil packs are replaced by collectible tins, which can sometimes be redeemed from the manufacturer in exchange for a certain number of the paper-foil packs as part of promotional events.

Original Extra Strong lozenges contain sugar, liquorice extract, menthol, eucalyptus oil, dextrin, tragacanth, and capsicum tincture.

The sugar free versions of the lozenges contain sorbitol, aspartame, menthol, vegetable-sourced sucralose, and acesulfame K. Often they have anti-caking agents added such as magnesium stearate. Each different flavour will have unique ingredients. For example, the blackcurrant flavour variant includes elderberry juice extract.
