1A brew of sweet birch. I break a handful of twigs (with unopened buds) into a quart jar, fill it with boiling water, and cap it tightly. The next morning, I pour off (and drink) the wintergreen- flavored tea, leaving the twigs in the jar. I pour another quart of boiling water over the (same) twigs. And so on, up to thirty times.
After the third or fourth brewing, try some of the liquid as a grease-cutter in the oven. Amazingly, the birch tea gets stronger the more often you use the twigs.
The leaf tea is reported to eliminate gravel and dissolve kidney stones when taken daily for a time, 1 to 1 1/2 cups a day.
A decoction of the leaves is sometimes recommended for baldness; or try the fresh expressed juice.
