The invention discloses a
capsule capable of reducing an incidence rate of postoperative
shivering and a preparation method thereof. The preparation method is characterized by comprising the following steps: (1) respectively distilling coarse
powder of glabrous sarcandra
herb, changnienia amoena, rhizoma anemones altaicae, poncirus
bark, asaraceae and erythrinae
bark through steam, extracting volatile oil, collecting and mixing the volatile oil for later use, and reserving dregs for later use; (2) uniformly mixing satyrium root, spina gleditsiae, rhizoma cimicifugae, fragrant
sarcococca herb,
amblystegium serpens and buckeye seeds with the dregs obtained from the step 1, adding 4 times of water, decocting twice in water with each time lasting for 1 hour, combining decoctions and standing; then adding 95%
ethanol which is 3-4 times as much as the decoction to the decoction, standing for 15 minutes, centrifuging for 20 minutes at 3000rpm / min, reserving a centrifugal solution, concentrating and spray-
drying the centrifugal solution to obtain a primary material; and (3) spraying the volatile oil obtained from the step 1 into the primary material obtained from the step 2, uniformly mixing and
grinding, filtering through a 60-mesh
sieve, and
filling in capsules. Clinical experiments prove that the
capsule disclosed by the invention has the characteristics of a good
curative effect and a relatively high safety on preventing
shivering after idiopathic general
anesthesia; the
capsule is worthy of clinical application and popularization.
