We all know now that it is a very common step to use sulfur powder for fumigation in the processing of Chinese herbal medicines. So why use sulfur powder products? What is the practical value of using sulfur powder for fumigation? The following is a simple understanding of this aspect by the production staff of sulfur powder:
First of all, we must know that fresh Chinese medicinal materials must contain water, which is not easy to preserve. Fumigate Chinese medicinal materials with sulfur powder, and the water content in them can be as high as 20% to 30% without mold. Even medicinal materials such as angelica are fumigated. Finally, the water content is increased by nearly 70%, which greatly increases the weight of the medicinal materials, and at the same time prolongs the shelf life, making it easier to store. In order to enhance the visual effect and make the Chinese medicinal materials look more shiny, the Chinese medicinal materials are actually more or less fumigated with sulfur powder, such as Gastrodia elata, lily, angelica and paeonol, etc. After fumigation, they are obviously more colorful and beautiful.
At the same time, in order to make the processing of Chinese medicinal materials more convenient, it can be quickly dehydrated and dried, and will not become corrupt and mildewed due to long-term non-drying, and at the same time can maintain good properties, so sulfur powder is used for fumigation, generally like platycodon, yam Medicinal materials such as Achyranthes bidentata, Trichosanthes, Radix Paeoniae Alba, Atractylodes Rhizoma Atractylodes Rhizoma Atractylodes Rhizome, Shui Pinellia and other medicinal materials will all be operated in this way. The last thing to keep in mind is that Chinese herbal medicines often need to be sliced, so they can be moistened first and then fumigated with sulfur powder. The traditional Chinese medicine slices are intact and not broken, and the overall properties are good, such as astragalus, yam, gastrodia elata, etc.
