Description

A kind of preparation method of Radix Rehmanniae Preparata decoction pieces
Technical field
The invention belongs to Technology of Processing Chinese Herbal Medicines field, it is related to a kind of preparation method of Radix Rehmanniae Preparata decoction pieces.
Background technology
Radix Rehmanniae Preparata function with cure mainly: YIN nourishing of enriching blood, beneficial essence fills out marrow.For blood deficiency and yellow complexion, severe palpitation, menoxenia, collapse Leak down blood, the hepatic and renal YIN deficiency, soreness of the waist and knees, osteopyrexia and fever, night sweat seminal emission, Heat Diabetes, dizziness, tinnitus, early whitening of beard and hair etc..
Traditional method concocting method has two kinds to record in " Chinese Pharmacopoeia " version in 2015, and respectively " (1) takes the Radix Rehmanniae Huang, according to stewed with wine method, stewes and exhausts to wine, take out, when dry in the sun to crust mucus is slightly dry, cut sheet or block, be dried, obtain final product.(2) take life Radix Rehmanniae, according to the method for steaming, steams to black profit, takes out, shine to when about most probably doing, cut sheet or block, be dried, obtain final product." conventionally produced effect Rate is low, and yield is low, and energy consumption is big, is not suitable for large-scale industrial production.
Cn103285305a discloses a kind of preparation method of Radix Rehmanniae Preparata decoction pieces, including selecting, stepping, cleaning, steam soft, dry Do, pile up moist, steaming and decocting, microwave drying again, screening, packaging and other steps.This processing step is more complicated, after needs will be dried Semi-finished product load gunnysack, pile up into 1-2 rice height, shady place place carry out within 10-15 days piling up moist this technique not only step Various, and process time is longer, and efficiency is low, and needs to carry out special microwave drying, and needs after steaming and decocting again Carry out microwave drying, energy consumption is big, high cost.
Therefore, obtain a kind of simple, efficient, energy saving Radix Rehmanniae Preparata decoction pieces preparation method in this area expectation.
