Preparation method of honey plast

Preparation of raw materials:

1, coarse grinding raw materials: refers to the rhizome, loose, hard and cellulose-containing traditional Chinese medicine that is not easy to grind in the prescription. Generally, it is crushed to a diameter of 0.2-0.5CM, and then the paste is extracted.

Removing impurities, pulverizing, pouring into a container (preferably stainless steel pot), and soaking in 75% ethanol for 48 hours or longer, wherein the ethanol is 5CM higher than the powder. Bubble intrusion junction

Binding, filtering, placing ethanol separately, pouring the residue into a container filled with water, heating with slow fire for 4 hours, filtering, and pouring out the liquid medicine. Mixing the ethanol extract with the decoction, filtering,

Fire first and then simmer until the flag is hoisted.

Technology: crude drug-diluted 75%- soaked in a container-filtered out-ethanol extract.

Residue-in a container-heated with water-filtered out-decocted with water.

Decoct with alcohol and water-mix-120 mesh sieve and filter-write first, then concentrate on fire until the flag is hung.

2. Fine grinding: (Fine material) refers to grinding the precious, aromatic, resin and Chinese medicines containing volatile oil in the prescription to 80- 100 mesh.

3, honey refining:

1。 Honey ensures the humidity and transdermal absorption of the plaster, but refined honey must be used. The choice of honey is also very important.

It is best to use pure natural honey, but it is not suitable for bottled honey on the market.

2。 The purpose of honey refining is to remove impurities, such as dead bees and wax; Destroy enzymes to kill microorganisms; Properly remove some moisture to enhance adhesion; Promote the transformation of some sugars and increase stability.

3。 Honey refining: put honey into a pot, heat it to boil, remove floating foam and impurities, and continue to heat and boil it in the pot, which is divided into tender honey and medium honey. Old honey.

Next, we will begin to make the finished gypsum.
