Embodiment Construction

[0005] After the yam medicinal materials are harvested, they are cleaned to remove impurities such as sediment and non-medicinal parts, washed with tap water while fresh within 6 hours, and cut into 3mm thick slices. Add 5 times the weight of the tablet to 70°C purified water, stir for 30 minutes, filter, squeeze the dregs to extract the juice. Then add 8 times the weight of pure water at 50-70°C to the above medicinal residues, stir at a low speed for 20 minutes to extract, filter, squeeze the medicinal residues again, and collect the medicinal juice. Combine the above medicinal juices, concentrate under reduced pressure, set the temperature at 70°C, and concentrate to a clear paste with a relative density of 1.20. The resulting clear paste was frozen at -80°C for 12 hours, and then vacuum freeze-dried at -40°C. The dried product is vacuum-dried at 60°C until the water content is 8%, crushed, passed through a 60-mesh sieve, and vacuum-packed to obtain the finished product.
