316. BETULA alba. BIRCH TREE. The bark and Sap.--Upon deeply wounding or
boring the trunk of the tree in the beginning of spring, a sweetish
juice issues forth, sometimes, as is said, in so large quantity, as to
equal in weigth to the whole tree and root: one branch will bleed a
gallon or more a day. This juice is chiefly recommended in scorbutic
disorders, and other foulnesses of the blood: its most sensible effect
is to promote the urinary discharge.
317. BORAGO officinalis. BORAGE. The Flowers.--An exhilarating virtue
has been attributed to the flowers of borage, which are hence ranked
among the so called cordial flowers: but they appear to have very little
claim to any virtue of this kind, and seem to be altogether
insignificant.
318. BRYONIA alba. WHITE BRYONY. The Roots.--This is a strong irritating
cathartic; and as such has sometimes been successfully exhibited in
maniacal cases, in some kinds of dropsies, and in several chronical
disorders, where a quick solution of viscid juices, and a sudden
stimulus on the solids, were required.
319. CALENDULA officinalis. MARIGOLD. The Flowers.--These are supposed
to be aperient and attenuating; as also cardiac, alexipharmic, and
sudorific: they are principally celebrated in uterine obstructions, the
jaundice, and for throwing out the small-pox. Their sensible qualities
give little foundation for these virtues: they have scarcely any taste,
and no considerable smell.
