However, standardization of Saw Palmetto extracts is often compromised by imprecise and even harmful extraction methods. Palmettx is manufactured using Inter-Cal s proprietary PureXtrax TM supercritical CO 2 extraction method which processes botanicals naturally, without chemicals, toxic solvents or excessive heat. It is an ecologically sound process that assures the highest product integrity and quality, excellent storage stability and virtual elimination of all enzymes, microorganisms, viruses, molds and spores. On Site Control Grown, hand-harvested, processed, and supercritically extracted entirely in the United States to guarantee the highest quality. Cultivation methods provide control of planting, harvesting, drying and cleaning.
Cultivation maintains genetic diversity of native plant populations for the future.
Fruits are cryogenically ground to ensure optimum potency and recovery of active components. Long-term supply agreements ensure steady availability of material and quality consistency. CO 2 extraction represents the cutting edge in botanical purification technology and is predicted to replace all other solvent extraction methodologies. This demand will be driven largely by consumer and governmental concerns about the use of hazardous solvents in food and nutraceutical products. Low CO 2 extraction temperatures preserve product integrity and quality.
