A cup-shaped pot and lid. The decoration is made by hand and in the centre, in a draped-looking sign, is the name of the substance: " P. Sang. Drac", or dragon’s blood powder
Dragon's blood powder is a red resin from the Dracaena draco, an emblematic tree of the Canary Islands with roots that provide a gum resin used as a stimulant, astringent, abortant, toothpaste and against rheumatism.
This was acquired by Tomàs Balvey i Paré in 1927 from a potter in Barcelona, along with the rest of the nearly two hundred pots. They were still in use until 1943, when his grandson, Tomàs Balvey i Bas, closed the pharmacy.
