p. 132-133: ROSA refrigerat & astringit, sed sicca multo magis. Succus recentibus foliis exprimitur, defectis sorsice unguibus (sic appellantur candidæ foliorum partes) reliquum in plia premi & teri debet in umbra donec cogatur, asperis.  [ROSE is cooling & astringent, but dry much more so. The juice is squeezed out of fresh leaves, when the nails are broken (so the white parts of the leaves are called), the rest is pressed into folds and must be rubbed in the shade until it is forced, rough.]
