Insect repellent. Aid to digestion. Kills worms. May be added to shampoo or soap, esp for oily skin/hair. Stems and foliage yield yellow dye. Magical herbs. Winter kill 2013. This may have adverse affect on neighbor plants, and I did have problems with the rhubarb while this was alive. Don't replace, or do so out in the field somewhere, it's really a large and unkempt plant.
