Like many of you, I'd like to step back in time on occasions -- at least as much as a particular spot will allow me to.
A visit to Farmacia de la Estrella on Defensa Street in Buenos Aires, near the Basilica de San Francisco, will take you back to the 19th century. Built in 1835, the pharmacy is still actively functioning and a busy place dispensing homeopathic remedies to those in need. It is said to be the oldest pharmacy in Buenos Aires.
The woodwork is original mahogany, and the murals are lovely. You'll see lots of old jars from a time when medicine didn't come in blisterpacks or disposable bottles. The pharmacy hasn't changed much over the past two centuries and is worth a detour to see when visiting the city. The staff are cordial and very used to tourists, so don't be shy about popping in.
