This 10 ½” blown glass Apothecary Jar is labeled Erythrox: Coca. Erythrox: Coca is short for Erythroxylum Coca, a stimulant that was used to overcome fatigue and an anesthetic and analgesic to alleviate pain from headaches, wounds, sores, etc. all popular medications in the 19th century, which is when this jar probably dates to. The jar retains its original painted tin lid and original paper label, fastened to the inside; there is also a soiled, illegible partial paper label on the back side. 4 1/2" diameter. Very fine condition with no cracks, lines or edge chips. Some minor paint wear and scratching on the lid. This ain’t for a cup of hot chocolate, but if you plan to use it for consumables, I’d suggest cleaning it thoroughly.
