Lollipop is a plant planted in Eurasia, also known as burdock. It is a perennial root vegetable, also known as "big root vegetable" or "root leaf vegetable". Bangen has a lot of mucus, which can help digestion and prevent constipation. In addition, the roots are rich in vitamins and minerals, which help to enhance immunity and promote health.

Besides edible roots, leaves can also be used for making tea and making medicines. In traditional medicine, bamboo leaves are considered to have hypoglycemic, hypolipidemic, detoxification and anti-inflammatory effects. Besides, leaves are also related to beauty, which helps to keep skin healthy and clean.

In Japan, braised pork is widely used in daily diet and is often added to soup and braised dishes. Gao Bang is a traditional Japanese snack, which is made of stick powder and has a soft taste. In addition, there is a drink called "burdock tea", which is made of processed leaves. Because burdock tea tastes bitter and not suitable for the public, only a few Japanese like to drink it.
