Passion Flower's RSO+ is a Recreational Wellness blend of 50% Ethanol and 50% PHO. Food grade ethanol's superior bi-polar solvent benefits deliver water-soluble cannabis components such as polysaccharides, flavonoids, and alkaloids. Propane on the other hand is a superior non-polar solvent for cannabis and delivers a higher concentration of cannabinoids, and a richer terpene and ester profile, in an amber gold delicious extract.
