Roy Clarke likes his descriptive pairings, in Open all hours there is an episode centred around Fig biscuits and Inspirational Toilet Rolls so Blood and Stomach Pills is not that unusual to include in a script and there are references in Still Open to all sorts of mystical medical products produced by some fictional Doctor [which Roy Clarke probably purloined from the Medicine Men who provided all sorts of mystical cures in the Wild West] that Granville tries to flog .
