Extraction technique matters when producing quality cannabis oils. NuSierra relies on CO2 extraction, which takes longer but produces superior results. CO2 extraction uses pressurized carbon dioxide to extract desirable cannabinoids from cannabis flower and produces for NuSierra a wonderful amber-colored oil.
CO2 produces no toxic byproducts and is the standard extraction method in the herbal supplement and food industries. Conventional processes for extraction often rely on butane, propane or other hydrocarbons. While cheaper these processes have significant limitations and concerns.
