157. Iouis barba: i.e. houseleek; cold in the third degree and dry in the second degree; Platearius says that this herb serves for every purpose for which the common sorrel serves. If the juice of this herb be put warm in the ear, it will help with deafness. Take half a quart of the juice of houseleek, and the same amount of the juice of sorrel, and half a quart of vinegar, mix them together, and take powder of the stinking iris, fennel, parsley, hart's tongue fern, maidenhair spleenwort and root of horseradish, boil them well until it has been reduced in volume by a quarter, purify with honey and white of egg, and preserve it in a tin vessel; if this be drunk like any oximel it will open the oppilation of the liver, spleen, and kidneys.
