Herb Introduction
The shape of the oak leaves is too familiar to need description. The flowers are of two kinds; the male, or barren, in long drooping catkins, 1 to 3 inches long, appearing with the leaves, and the leaves and the fertile flowers in distant clusters, each with a cup-shaped, scaly involucres, producing, as fruit, an acorn 1/2 to 1 inch long. oak is a large, native North American tree; usually 60-100 feet high, but may grow as tall as 150 feet with a trunk diameter up to 8 feet. White oak bark is pale gray, and the leaves have rounded or finger-shaped lobes. The alternate, deciduous leaves are bright green and hairless, widest beyond the middle, with 3-5 pairs of rounded lobes. Light brown, ovoid acorns grow on current year's twigs in bowl-shaped cups enclosing a quarter of the acorn.

Externally, this decoction has been advantageously employed as a gargle in chronic sore throat with relaxed uvula, and also as a fomentation. oak is also serviceable as an injection for leucorrhoea, and applied locally to bleeding gums and piles.
