Burdock is highly effective against Posion Ivy & Oak
Make a strong tea of Echinacea root and Burdock root to help move the Poison Oak through your system faster. Put two tablespoons of Echinacea root and one tablespoon of Burdock root into a quart jar and pour boiling water over the herbs. Let the herbs steep in the water for four hours and then strain the herbs out. Make a fresh quart each day and drink three to four cups a day for several days. Also make sure you drink lots of plain water.
