From The Good Housewife's Jewel. by Thomas Dawson. (Southover Press, 1996) originally published 1596-7. It is a drink for those recovering from the stone, supposed to clear the bladder.

The Drink
Take rosemary with thyme, and seethe them in running water with as much sugar as will make it sweet from a quart to a pint. Use the quantity of your herbs according to your discretion, so that it may savour well of the herbs. And so use it nine mornings, six or seven spoonfuls at a time.
