How to boil black ointment need those ingredients

Black ointment is a hard paste of lead made by frying medicinal materials in edible oil and reacting with huangdan at high temperature after removing dregs.

(A), the selection of substrate raw materials and the treatment of medicinal materials

1. Vegetable oil: the texture of pure sesame oil is good. Its advantage is less foam when refining, favorable operation. And made of ointment color bright, sticky, good quality. Can also be used cotton oil, rapeseed oil, peanut oil, etc., should not use soybean oil.

2. Huangdan: also known as chapter Dan, lead Dan, red Dan, Tao Dan, orange-yellow, heavy, powdered, the main become four lead oxide, the purity requirements in more than 95%, and does not contain water. (Can be bought in large pharmacies or chemical stores)

3. Treatment of medicinal materials: medicinal materials can be divided into general medicinal materials (coarse materials) and fine materials of two types. Coarse material for general Chinese medicine roots, stems and leaves, fine material for the precious medicine and aromatic medicine. Coarse material according to the prescription to take a good, and appropriate crushing, for boiling withered slag preparation. Fine materials such as musk, etc. into a fine powder standby, spread coated in the surface of the paste; soluble or volatile fine materials such as ice chips, camphor, myrrh, frankincense, etc. can be studied as a fine powder standby, put into the melted paste before spreading and mixing. (Fine powder should be 120 mesh sieve)

(2), the traditional black ointment production process

1. The extraction of medicinal materials (boiled withered dregs): take vegetable oil in a pot, slightly warmed the medicinal materials into the heating and stirring until the medicinal materials fried to the surface of the dark brown internal charred to the degree. At this time, the temperature can reach 220 degrees, after frying can be used wire sieve to remove the dregs of the drug, to remove the dregs of the oil for the drug oil. (The best pot with a copper pot, control the temperature can be used special high-temperature thermometer, medical equipment malls are sold)

2. refining oil: take the above oil to continue to simmering, to be the oil temperature rises to 320 degrees (must reach the temperature, it is very critical), change to medium heat. Oil refining fire: one is to see the thermometer, to reach the specified temperature; two is to see the oil smoke, the beginning of light green, gradually black and thick, and then white smoke, no wind when the white smoke straight up; three is to see the oil flower: the beginning of the boiling, oil flower in the pot wall around the vicinity of the periphery, when the oil flower to the pot in the center of the collection of the degree; four is to see the drop into a bead: take a small amount of medicinal oil drops in the water, do not spread into a bead for the degree. (This level is the most difficult, must be refining oil to dripping beads, must pay attention to fire prevention, the temperature is too high)

3. Dan into a paste: oil refining, away from the fire under the Dan, 500 grams of oil can be added to the general 250 grams or so Dan, yellow Dan in the next before drying and 100 mesh sieve. Add a small amount of Dan, stirring while adding, be sure to stir in the same direction. Stir into a viscous paste, the paste does not stick to the hand, pulling the wire constantly for good, too hard is old, too sticky is tender.

4. To remove the fire poison: the paste is made into cold water, soak, change the water every day, ten days after the paste into.

5. Take the poultice group placed in a container, in a water bath or melting on the fire, will be fine material into, stir, take a certain amount of paste with a bamboo stick in the kraft paper or poultice cloth can be, musk and other particularly valuable medicine and volatile ice, camphor, mint and other can be sprinkled on the last.
