Polygonum cuspidatum paste and preparing method thereof

The invention discloses polygonum cuspidatum paste. The polygonum cuspidatum paste is prepared from, by weight, 2,800-3,200 parts of polygonum cuspidatum powder, 8,000-10,000 parts of sesame oil, 400-500 parts of solid paraffin and 250-350 parts of borneol. The preparing method of the polygonum cuspidatum paste comprises the steps of 1, weighing all components; 2, heating 40-60% of the weighed sesame oil to 160-180 DEG C, after white smoke is generated, adding the solid paraffin, and stirring and dissolving the solid paraffin to obtain a primary mixture; 3, stopping heating the primary mixture, naturally cooling to the temperature of 100-110 DEG C, after the white smoke is dispersed, mixing and uniformly stirring remaining sesame oil and the polygonum cuspidatum powder, afterwards, slowlyadding the sesame oil and the polygonum cuspidatum powder into the primary mixture in batch, preventing overflow, and fully stirring to obtain an intermediate mixture; 4, continuing to naturally coolthe intermediate mixture t
