4. Harvesting and processing
Winter harvest. Dig out the roots, wash them, scrape off the cork skin, cut off the head, stem, and fine tail, and cut them into about 15 cm long sections. Cut the half of the large strips into two halves and smoke them with sulfur yellow for 2-3 days until the body is soft. Take them out when the body is soft. When the sun is 60% dry, change to sun exposure, smoke them with sulfur yellow at night, and then sun them until the feet are dry to form "pink kudzu strips"; After washing again, scrape off the cork skin, cut it vertically into square pieces, smoke with sulfur yellow until soft, and dry in the sun to form "Pueraria lobata slices".
5. Characteristics of medicinal herbs
Cylindrical, spindle like, or semi cylindrical; Some are thick slices that are longitudinally or diagonally cut, with varying sizes. The surface is yellow white or light brown, and those without cork removal are grayish brown.
