Embodiment 1

[0010] Embodiment 1, preparation has the oyster extract that promotes postpartum uterine contraction:

[0011] (1) Appropriate amount of oyster meat, homogenized;

[0012] (2) Add 1.5 times the volume of distilled water, and ultrasonically assist extraction at 30°C for 25 minutes;

[0013] (3) Stir and extract in a water bath at 30°C for 2 hours, centrifuge at 4000r / min for 5 minutes, take the supernatant, repeat the above operation for the residue, combine the filtrates, concentrate under reduced pressure to 1 / 3 volume, and freeze-dry to obtain the oyster extract.

Embodiment 2

[0014] Example 2: Effect of Oyster Extract on Uterine Contraction of Isolated Mice

[0015] Preparation of isolated mouse uteri: 2 days before the experiment, non-pregnant female mice were intraperitoneally injected with estradiol valerate every day to improve the sensitivity of the uterus to drugs; the mice were killed quickly by cervical dislocation, and the uteri were taken out by laparotomy to make about 1.0 cm strips of uterine smooth muscle. Put the uterus ligated with silk thread into a Maxwellian bath filled with 20ml, fix one end of the silk thread ligated to the specimen fixing hook in the bath, and connect the other end to the tension transducer, and give the uterus a load of 1g. After the uterine contraction is stable, the normal contraction curve is recorded. Add 1 drop of motherwort aqueous solution (as a control) and various concentrations of oyster extracts to each group, and after the uterine contraction is stable, use Biolap420E + The biological signal acq...

Embodiment 3

[0018] Embodiment 3: Preparation of oyster extract tablet

[0019] prescription:

[0020] Oyster Extract 100mg

[0021] Lactose 100mg

[0022] Starch 295mg

[0023] Magnesium Stearate 5mg

[0024] Total 500mg

[0025] Weigh out the main ingredients respectively, mix oyster extract powder, lactose, and starch through an 80-mesh sieve, wet granulate, dry, mix with magnesium stearate after integration, compress into tablets, and compress into tablets of 500 mg each agent.
