Materia Medica

Antilithics

from the Sulphate of Iron, the decoction of the leaves is a better
preparation than the infusion, as their powers are easier extracted
in the former way, though not sufficiently, I often give the leaves to
the patient to chew, and sometimes in powder. Uva Ursi exerts
verry little power upon the pulse, so little indeed that if we were
to estimate its utility by its action on the heart and arteries
we should esteem it of verry little importance. Physicians differ
in their opinion of this medicine. Dr Ferrier of Manchester
has given it in Nephritic Cases in moderate doses with manifest
advantage when the pain is acute he begins his treatment with
purging and bleeding, he then gives grs V [5 grains] of Uva Ursi with ½ grs [grain]
of Opium three or four times a day, when given to the extent of Ʒi [1 dram]
he found it to occasion nausea, he says that of 16 cases that
came under his care he discharged 12 cured, and I have not
found it to produce nausea tho I have employ’d it in larger
doses than Ferrier. I have not combined it with opium. I
can say without hesitation that it may be given largely
without injury. Savage gave Ʒij [2 drams] of it 3 times a day, the Uva Ursi
has been found usefull in different affections of the Urinary
System where there is no calculous DE Haen advised it in Ulcers
