Another ancient Celtic remedy, the burdock plant is now widely considered by many gardeners to be nothing more than a pesky weed. However, in contrast to modern day gardeners, the Celts considered all plants sacred, and understood that every plant has its value. Burdock has been found to be an excellent detoxifying herb as it triggers the body’s excretory systems such as the lungs, liver, kidneys, sweat glands, lymphatics and urinary systems, allowing them to expunge toxins and excess fluids.
