Embodiment Construction

[0005] After the rehmannia medicinal material is harvested, it is 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 to the medicinal residues, boil for 20 minutes to extract, filter while hot, 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 obtained clear paste is vacuum-dried at 80°C until the water content is 8%, crushed, passed through a 60-mesh sieve, and vacuum-packed to obtain the finished product. The content of verbascoside in the finished decoction pieces is 0.050%.
