50 year old Pine Bros Cough Drops

Mike Davidson asks his readers Is it ok to eat 50 year old cough drops. He won an auction for the medicinal sweets and then wondered if they could do him harm. Imagine buying cough drops that could possibly have the reverse effect, and give you a sore throat or tummy ache.

This is unlikely though as as one of his commenters who recently tested the toxicity/endurance levels of glycerol in some cough-suppressing syrups thought that

...there's not much chemical difference from the 50 year-old box to one you would buy at the drug store today.

The auction was for an unopened box of Pine Brothers cough drops from the 1950s or 60s. If you are feeling a little hoarse you may want to bid for your own cough drops. although I'd stick to a new packet from the chemist myself.
