Fisherman\'s Friend Blackcurrant Sugar Free Lozenges contain menthol, which helps sooth a sore throat. Delicious and strong flavoured lozenges, ideal for when you have a sore throat or are congested. About Fisherman\'s Friends Fisherman\'s Friends first came to be in 1865, when Fleetwood pharmacist James Lofthouse developed a menthol and eucalyptus liquid for fishermen to keep them warm on stormy nights. However, soon liquid proved not to be very practical on a rocking boat, causing him to create his famous lozenges instead. Since those humble beginnings, Fisherman\'s friend is now a global brand which is still a family business at heart.
