Burdock root, greater burdock or edible burdock root is called “gobou/牛蒡” in Japanese.
Its Latin name is Arctium lappa.
Although it is a root vegetable with great nutritious and even medical properties, it is commonly eaten only in Japan and Taiwan.
This species is native to the temperate regions of the old world, from Scandinavia to the Mediterranean, and from the British Isles through Russia, and the Middle East to China and Japan, including India.
It is naturalized almost everywhere and is usually found in disturbed areas, especially in soil rich in nitrogen. It is commonly cultivated in Japan.
It prefers a fresh, worked soil, rich in humus, and should be positioned in full sunlight. Burdock is very reactive to nitrogen fertilizer. Propagation is achieved through sowing the seeds midsummer. The harvest occurs three to four months after the seeding until late autumn, when the roots become too fibrous.
In shizuoka it is more and more cultivated in organic fashion with natural/organic fertilizer and no pesticides.
Greater burdock was used during the Middle Ages as a vegetable, but now it is rarely used, with the exception of Japan where it is called gobō (牛蒡 or ゴボウ), Taiwan (牛蒡), Korea where it is called ueong (우엉), Italy, Brazil and Portugal, where it is known as bardana. Plants are cultivated for their slender roots, which can grow about 1 meter long and 2 cm across.
Immature flower stalks may also be harvested in late spring, before flowers appear. The taste resembles that of artichoke, to which the burdock is related.
The root is very crisp and has a sweet, mild, and pungent flavor with a little muddy harshness that can be reduced by soaking julienned/shredded roots in water for five to ten minutes. The harshness shows excellent harmonization with pork in miso soup (tonjiru) and takikomi gohan (a Japanese-style pilaf).
A popular Japanese dish is kinpira gobō, julienned or shredded burdock root and carrot, braised with soy sauce, sugar, mirin and/or sake, and sesame oil. Another is burdock makizushi (rolled sushi filled with pickled burdock root; the burdock root is often artificially colored orange to resemble a carrot). In Kyoto, gobō can also be found as a snack food similar to potato chips. The root is eaten cooked and the young sprout can be eaten just like asparagus. Gobo is also used in tempura.
Apart of its obvious culinary value, it is also valuable for its high content in dietary fibers and beneficiary nutrients.
It has been utilized as a medicinal plant with diuretic, diaphoretic, and blood purifying capabilities. The Japanese have also recognized it to prevent cancer and combat diabetes.
