How is Ban Lan Gen prepared and processed?
Isatis tinctoria, also known as Woad or Dyer's Woad, is a herb that is native to Europe and parts of Asia. It prefers well-drained, fertile soil and a cool climate, and can be grown as a biennial or a short-lived perennial. The plant grows to a height of about 60-90 cm (24-36 inches) and has large, green leaves and small, yellow flowers. The leaves are used to produce a blue dye. It grows well in full sun and well-drained soil. It can be found in meadows, pastures, and along the waysides.
Ban Lan Gen is prepared and processed by first cleaning the roots, then slicing them into thin pieces, and finally drying them under the sun or in a low-temperature oven. The dried slices are then stored in a cool, dry place until they are ready to be used. The dried slices of the root can be used to make decoctions, powders, or pills. When making a decoction, the dried slices are typically simmered for 30-60 minutes and consumed as a tea. Powders and pills are often used as a more convenient form of consumption.
