Arctium lappa (aka burdock) the original blood purifier! Combine this with dandelion and you got an amazing brew! The Japanese call the burdock root gobo and they considered it a vegetable! I use it in my tea. I take the dry Burdock root and put it in a teabag and stick it in with my dandelion root!! Liver detoxifier and blood purifier all in one!! Burdock root is also one of the main ingredients in the Essiac tea that the Ojibwa Indians have used to cure cancer.
