The invention discloses a radix cyathulae fresh-cut medicinal slice processing technique. The radix cyathulae fresh-cut medicinal slice processing technique comprises, after radix cyathulae is harvested, quickly washing the radix cyathulae stuck with soil in a humid state, air-drying the washed radix cyathulae for 2-4 hours, fresh-cutting the radix cyathulae into round or elliptical slices, drying and vacuum-packaging the slices in polyethylene plastic bags and adding drying agent and antioxidants. According to the radix cyathulae fresh-cut medicinal slice processing technique, the radix cyathulae is washed and processed in a fresh state, so that losses of water-soluble effective constituents can be avoided, pollution led to by microorganisms and insect eggs in soil to the radix cyathulae can be reduced, slice production processes can be simplified, manufacturing costs can be reduced, medicinal effects can be ensured and clinical effects can be improved. The radix cyathulae fresh-cut medicinal slice processing technique can be in popularized implementation so as to achieve significant social and economic benefits.
