Coltsfoot Rock is a confectionary created from coltsfoot extract by the UK confectioners Stockley's Sweets, based in Oswaldtwistle, Lancashire, England.
As a product, it is a hardened stick of brittle rock candy flavoured with coltsfoot.
Coltsfoot rock has gained acknowledgements from the UK Regional Tourism Board, Lancashire Tourism Council and culinary organisations such as Gourmet Britain.
[citation needed] The recipe is secret to Stockley's Sweets and, as they are the only manufacturer, all products that are labelled as such have originated from Stockley's traditional factory.
[1] The history and popularity of the confectionery comes from its supposed medicinal benefits; originally the leaves of the coltsfoot plant were dried and then smoked, and this was thought to have relieved asthma.
