Product Description

Petasites japonicus, 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. It has also been introduced to southern British Columbia by Japanese immigrants.

The traditional preparation method for this vegetable involves pre-treating with ash or baking soda and soaking in water to remove harshness, which is a technique known as Aku-nuki. The shoot can be chopped and stir fried with miso to make Fuki-miso which is eaten as a relish thinly spread over hot rice at meals. The bulb-like shoots are also picked fresh and fried as tempura.

Petasites japonicus is used for treating asthma, oxidant stress and gastric ulcer in traditional Oriental medicine. The plant may contain plasma and hepatic lipid-lowering and antioxidant compounds.
