The difference between ginger and roasted ginger ginger charcoal.
In the processing practice, etc. in sand with fried for good, hot method has uniform heating, the advantages of uniform processing degree. And the processing time is short, less loss. Ginger charcoal should be a good fried (fried carbon method), easy to deal with. Because the processing degree, ginger carbonization less loss rate is generally 20%, while ginger carbonization, the loss rate is as high as 40%, resulting in higher costs.
Ginger and ginger functions are different, and the two processing methods, there are large differences in degree. Ginger more use of materials, processing time is short, pay attention to the expansion degree of drugs, intended to remove part of the volatile oil from partial to temperature. Ginger charcoal processing firepower, product carbonization and more attention to the color of the drug, intended to fry the carbon storage, partial hemostasis. Because of different processing methods to determine the different functions and indications of drugs, which is the fundamental difference between the two.
Ginger Shizai in "Shen Nong's herbal classic", the processed products of ginger first recorded in Chinese "typhoid fever". The Song Dynasty, "Tai Sheng Hui Fang" contained in the ginger in "gun", and a "carbon gun" ginger charcoal. We can think of ginger charcoal from the Song Dynasty as a product of dried ginger. The Ming Dynasty in the "preparation" law of Miao Xiyong pointed out: "if the ginger postpartum blood deficiency fever and bleeding are fried black, gun powder Hanxie Wenzhong, the management of lung Ziou students". "Pointed out:" in the "compendium of Materia Congyuan ginger ginger black gun that posterity banthine gun is pungent ginger, if processing diminished, too, nature does not exist, that the bitter ginger charcoal, not spicy, the frivolous is not real, and not the function etc.". The "national processing standard of traditional Chinese medicine" specifically to distinguish the two: "gun Jiang Wen in the cold, abdominal pain, vomiting and diarrhea for spleen deficiency. Ginger carbon temperature by bleeding. Attending vomit blood due to Yin deficiency". So that the roasted ginger charcoal should be two kinds of different processed products of Rhizoma zingiberis.
