It has become naturalized nearly everywhere, growing in disturbed areas, especially where the soil is rich in nitrogen. Burdock's starchy root has a naturally fibrous cortex, so any accompanying fluffy or web-like material occurs normally. Burdock root has a reputation for being a good liver supporting herb and a blood purifier, in addition to traditional use as a diuretic and diaphoretic.
