viij; anoint, mixing with vinegar. The following simple remedies are particularly applicable for psora: Stavesacre, bitter lupins, cardamom with vinegar, the root of lily with honey, turpentine rosin, sulphur, chick peas, goat’s dung; and these compound ones—mix equal parts of chalcitis and misy with wine, and anoint the more humid kinds of psora.—_Another_: Boil the tender leaves of rose-bay in a sextarius of oil until they are dried, and, throwing away the leaves, add to the oil oz. iij of white wax, and, after it is dissolved, cool and sprinkle upon it oz. j of sulphur vivum, and anoint in the sun or in the bath. Some boil also squills with the rose-bay.—_Another_: Of diachylon, oz. ij; of wax, oz. ij; of oil of roses, oz. j; of litharge, oz. iij; of ceruse, oz. iij; of liquid pitch, oz. vj; of the dross of silver, oz. ij; of siricum, oz. ij; of vinegar, what will be sufficient for the trituration of the dry things.—_Another_: Of ceruse, oz. ss; of starch, oz. ss; of lead, oz. j; of red lotuses, or of alkanet, oz. ij; of wax, oz. vj; of oil of roses, oz. ix; boil the alkanet properly with the oil of roses, and then add the other things.—_Another_: Take ten eggs, or as many as are required, and having macerated in the most acrid vinegar until their shell become tender; boil in the vinegar the yelks of them; having triturated with rose-oil and what remains of the vinegar a moderate quantity of litharge, anoint, when of the consistence of the sordes of oil in baths.—_Another_: Three yelks of eggs out of vinegar; of rose-oil, oz. vj; of sulphur vivum, oz. iij; having triturated the yelks of the eggs and the sulphur with the vinegar, add the cerate. And litharge triturated with vinegar and rose oil, until it be of the consistence of a plaster, cleanses the most acrid kinds of psora; and the detergent ointments from dock, and the most of those for elephantiasis, answer well in general with leprosy and psora. * * * * * COMMENTARY.
