Barba sina: i.e. roseroot; it is cold in the first degree and dry in the second degree; it has the styptic virtue; if its foliage be dried and powder made of it, and it be put in old wounds, it will help them; it is said that its flower is more powerful than the herb itself; this herb serves well against pulmonary tuberculosis; its roots have the cleansing virtue, and its tops have the styptic virtue; it comforts the stomach and does not allow the other humours to descend to it. Avicenna says that there is no better medicine than this in the case of ulcers of the intestines; and that it stops excessive flux in women if it be drunk in water or in wine, or if it be applied as a plaster to the navel.
