Place 1/2 gallon water, dandelion root and burdock root into large saucepan. Bring water to boil.
Simmer 20 minutes, then remove from heat.
Add remaining herbs. Cover. Let sit overnight.
In the morning, strain equal amounts into 1/2 gallon mason jars. (Each jar will be only half full.) Add remaining filtered water to each jar, to fill. Refrigerate, drinking 1-2 glasses daily.
