Inonotus bbliquus (Chaga) Dual Extraction Process is a technique to extractmedicinalcompounds from inonotus obliquus (Chaga) while maintaining the medicinalcompounds inhigh level. For instance, with this dual extraction process results in highpercentage ofpolysaccharides, over 50 percent. Inonotus bbliquus (chaga) Dual ExtractionProcess includes ofusing three extraction processes: hot water extraction , alcohol [ethanol]extraction, and at thefinal step, we mix the extracted chaga-liquid from the hot water extractionand the extractedchaga-liquid from alcohol extraction as 1:1 ratio. Then it is atomized intothe spray dryer andtransforms from liquid form to powder form. Therefore, the 5:1 concentratedchaga powder ismade.
