Petasites japonicus, (Japanese: 菜蕗) also known as Fuki, bog rhubarb, or giant butterbur, is an herbaceous perennial plant in the family Asteraceae. It is native to Japan, where the spring growth is relished as a vegetable.



The traditional preparation method for this vegetable involves pre-treating with salt and soaking in water, a technique known as itazuri, or removing harshness.


Like other Petasites, fuki contains pyrrolizidine alkaloids, which have been associated with cumulative damage to the liver and tumor formation.[1]
