 juicing of fresh cannabis leaf or whole plants to treat a variety of ailments are likely attributable to the role that CBDA and THCA play on various biological targets as enumerated above.
CBDA and THCA can also be extracted and purified out of most any other cannabis extract (Wohlfarth et al 2011) but, short of the capabilities of sophisticated chemical separation of CBDA and THCA from all other cannabinoids in a lab, one will most easily obtain an extract with a much higher percentage of the carboxylic acid cannabinoids via cold-process extracts of the fresh plant. The resulting extract must continue to be stored in a cool, dark place (Taschwer 2015) in order to preserve its unique characteristics, and should be ingested rather than smoked if the goal of therapy includes reducing the psychoactive effects produced by THC.
