  The present invention relates to an improved method for preparing a medicament comprising a Taraxacum plant root extract for the treatment or prevention of a cancer. In one aspect, the method comprises freezing Taraxacum plant root to obtain a frozen root stock, said freezing step being selected to effect at least partial disruption of one or more root cells; dry grinding the frozen root stock to obtain a ground root powder, wherein during said dry grinding step the frozen root stock is maintained at a grinding temperature below about 40° C.; steeping the ground root powder with a solvent to obtain a suspension having a liquid extract portion and a solid particle portion; and separating the liquid extract portion from the solid particle portion to provide a separated liquid extract for use in the medicament.

  本发明涉及一种改进的方法，用于制备包含蒲公英植物根提取物的药物，以治疗或预防癌症。在一个方面中，该方法包括冷冻蒲公英植物根以获得冷冻根浆，所述冷冻步骤被选择用于至少部分破坏一个或多个根细胞；干磨冷冻根浆以获得研磨根粉，其中在所述干磨步骤中，冷冻根浆保持在低于约 40°C 的研磨温度下；用溶剂浸泡研磨根粉以获得具有液体提取物部分和固体颗粒部分的悬浮液；以及从固体颗粒部分分离液体提取物部分以提供用于药剂的分离液体提取物。
