High cannabinoid full spectrum extracts (HCFSEs) represent a premier class of cannabis concentrate that aims to capture the maximum diversity of beneficial medicinal and psychoactive compounds from the cannabis plant into concentrated form. HCFSEs utilize specialized post-processing filtration and separation techniques to finished distillates that contain very high total cannabinoid concentrations in addition to the full range of aromatic terpenes and lesser known accessory phytochemicals. This elevated cannabinoid content distinguishes HCFSEs from other full spectrum extracts and further potentiates effects due to the abundant presence of rare minor cannabinoids alongside the major ones like THC and CBD. The rich, inclusive mixture of both major and minor cannabinoids adds greater dimension and nuance to the holistic experience compared to single source isolates. By amplifying the comprehensive suite of synergistic cannabis compounds, full cannabinoid spectrum extracts like HCFSE may help consumers realize the full benefits of the entourage effect. Supported by accumulating scientific research, HCFSEs offer elite cannabis connoisseurs and medical patients alike a genuinely refined top-shelf distillate product centered around unparalleled cannabinoid complexity.
