**Chemists in East Coast seaports are frequently asked for Riga Balsam and it has been assumed that Friar's Balsam is intended, but true Riga Balsam contains neither benzoin nor aloes. It is a favourite all-round medicine in Riga, being especially esteemed as a stomachic, cold cure, and pick-me-up. It is strongly spirituous and is sold in wine shops rather than by chemists. There are several makers. A sample examined for the purpose of this note was dark brown in colour with a pleasantly aromatic taste.
