[0004] In view of the above-mentioned shortcomings, there have been three new preparation patents about Huahong compound medicine: "Huahong pill and its preparation method" (patent application No. 03124509.9); "Huahong dispersible tablet and its preparation method" (Patent No. CN 200410023398.7); "Huahong soft capsule and its preparation method" (Application No. 200410004558.3), respectively described the preparation method of the new dosage form of Huahong in the three patents, the extraction process of the medicinal material has not been significantly changed, and still retains a part of the original powder of the medicinal material for use as medicine, (preparation For details of the process and prescription, please refer to the Compilation of Standards of Chinese Patent Medicine of the State Drug Administration——The local standard of Chinese patent medicine has risen to the national standard part "Gynecology Subvolume").
