Quercus, White Oak. The fluidextract of the bark is an astringent, antiperiodic, and tonic in 15 to 30 I. doses. It is of value in certain bowel troubles as an astringent, in obstinate intermittents, exhausting sweats, diabetes, and passive hemorrhages. The decoction is employed upon ill-conditioned ulcers, in sore throat as a gargle, and as a wash upon the skin in debilitating disease with relaxation and exhaustion. Spiritus glandium quercus, or distilled spirit of acorns, is given to allay the craving for alcoholic drinks. (Ten drops in water, two or three times a day.)
