This is a 1/8 cup measuring cup, which also equals 1 fl. oz., 30 ml, or 2 Tablespoons.  These work great for measuring out a serving of the Essiac decoction. It is also handy for measuring the dry herbs for making the decoction.

One level 1/8 cup of Essiac dry herbs = approx. 10g, enough for one quart...once you get it made up, pour the decoction into this to measure out a one oz. serving!
