When the body of alcoholic Jeremy Pearson is found dead, Rosemary, when comforting his wife Marcia, goes to the bathroom cupboard for an aspirin and later tells Laura there was a bottle of 'Betabuse' in the cupboard. What she is referring to in real life is Disulfiram, commonly known as 'Antabuse', used to make alcoholics vomit if they drink after taking a dose of the medication.
This is the episode of Laura and Thyme where Laura's two children also appear: Ryan Philpott as Matthew Thyme and Daisy Dunlop as Helena Thyme.
