Little is known about its history: its founder was probably Salvador Roa y Abela, and in 1887 it passed into the hands of Mariano Passapera Campdera, a pharmacist and full member of the Royal Academy of Natural History. In 1981 the current pharmacist, Ángeles Jiménez Guerra, acquired the establishment. It contributes to the Spanish pharmacopoeia with its famous preparations against chilblains. At the beginning of the 20th century, he sold a remedy called Frilax against rheumatism for five pesetas. Illustrious figures such as the philosopher Zubiri or the mayor of Madrid, Enrique Tierno Galván, frequented the establishment.
