1. the preparation method of the antipruritic medicine of a heat clearing and damp drying, dispelling wind, it is characterized in that, the weight portion that this medicine material forms is:

  • Radix Sophorae Flavescentis 5-20, Rhizoma Coptidis 5-20, Flos Carthami 0-5, Rhizoma Chuanxiong 5-20, Flos Caryophylli 1-10, Radix Ginseng 2-10, Fructus Mume 5-20 Flos Sophorae Immaturus 5-20, Radix Paeoniae Alba 5-20, Fructus Schisandrae Chinensis 5-20, Rhizoma Belamcandae 5-20, Galla Chinensis 5-20g, Flos Cleistocalycis Operculati 5-9, Alumen 30-60, sodium benzoate 1-5;

    Preparation method is characterized in that may further comprise the steps;

    (1) get Radix Sophorae Flavescentis, Rhizoma Coptidis places multi-function extractor, add 3-10 and doubly measure the airtight 50-60 of being heated to ℃

    stopped heating behind the 30-80% ethanol, beat and left standstill warm macerating 24 hours after circulation 10-20 minute, beat circulation primary in every 1-4 hour, each 10-20 minute, filter, filtrate is deposited in addition, medicinal residues add 3-8 and doubly measure the airtight 50-80 of being heated to ℃

    stopped heating behind the 30-80% ethanol, beat and left standstill warm macerating 24 hours after circulation 10-20 minute, beat circulation primary in every 2-4 hour, each 10-20 minute, filter twice filtrate for later use of merging;

    (2) get Flos Carthami, Rhizoma Chuanxiong, Flos Caryophylli, Radix Ginseng, Fructus Schisandrae Chinensis, Flos Cleistocalycis Operculati and place multi-function extractor, add 3-10 and doubly measure the airtight 50-80 of being heated to ℃

    stopped heating behind the 30-80% ethanol, beat when leaving standstill warm macerating 12-24 after circulation 10-20 minute, beat circulation primary in every 2-3 hour, each 10-20 minute, filter, filtrate is deposited in addition, medicinal residues add 3-10 and doubly measure the airtight 50-80 of being heated to ℃

    stopped heating behind the 30-80% ethanol, beat and left standstill warm macerating 24 hours after circulation 10-20 minute, beat circulation primary in every 1-3 hour, each 10-20 minute, filter twice filtrate for later use of merging;

    (3) get Fructus Mume, the Flos Sophorae Immaturus, the Radix Paeoniae Alba, Rhizoma Belamcandae, Galla Chinensis and place multi-function extractor, adding 5-10 times of water gaging heating decocts 1-3 time, each 1-3 hour, in boiling time, beat circulation primary 5-10 minute after boiling, vapour pressure 0.05-0.08Mpa, temperature 98-100 ℃

    , filter the 1/8-1/5 that three filtrates of merging are concentrated into original volume, add while hot Alumen, stirring is all dissolved Alumen, gets supernatant after leaving standstill and deposits in addition, precipitate is put centrifuge and is discarded precipitate after centrifugal, and centrifugal liquid and supernatant merge for subsequent use;

    (4) alcohol precipitation tank is put in the pure immersion such as the water extraction liquid such as the Fructus Mume Flos Sophorae Immaturus and Flos Carthami Rhizoma Chuanxiong and mixed, adding concentration is that the 20-30% sodium hydroxide solution is regulated pH value to 2.0-6.0, leaves standstill 12-24 hour, gets supernatant for subsequent use;

    (5) supernatant that step (4) is made and Radix Sophorae Flavescentis Rhizoma Coptidis alcohol immersion merging stir, and the adding sodium benzoate stirs and makes it dissolving, leaves standstill, and filters, and adds an amount of water and makes external preparation.
