Duke of Portland’s Gout Powder.
Under this title a powder had a great reputation about the middle of the eighteenth century, and well on into the nineteenth century. The powder was composed of aristolochia rotunda (birthwort root), gentian root, and the tops and leaves of germander, ground pine, and centaury, of each equal parts. One drachm was to be taken every morning, fasting, for three months, and then ½ drachm for the rest of the year. Particular directions in regard to diet were given with the formula.
The compound was evidently only a slight modification of several to be found in the works of the later Latin authors, Aetius, Alexander of Trailles, and Paul of Egineta. These were entitled Tetrapharmacum, Antidotus Podagrica ex duobus centauriae generibus, Diatesseron, and other names. The “duobus” remedy was an electuary prescribed by Aetius, and a piece the size of a hazel nut had to be taken every morning for a year. Hence it was called medicamentum ad annum. This, or something very like it, was in use in Italy for centuries under the name of Pulvis Principis Mirandolæ, and spread from there to the neighbouring countries. An Englishman long resident in Switzerland had compiled a manuscript collection of medical formulæ, and his son, who became acquainted with the Duke of Portland of the period, persuaded him to give this gout remedy a trial. The result was so satisfactory that the Duke had the formula and the diet directions printed on leaflets, and these were given to anyone who asked for them.
