CBD is an abbreviation for Cannabidiol (pronounced; Canna-Bi-Diol). Cannabidiol is a by-product of the Non-Enzymatic Decarboxylation (non-enzymatic catalyzed release of COOH) of CBDA (Cannabidiolic Acid).
CBDA-Synthase + CGBA = CBDA
CBDA + Non-Enzymatic Decarboxylation = CBD
In general, Non-Enzymatic Decarboxylation (non-plant release of CO2) for conversion of CBDA to CBD begins at 182.5C so this does not convert naturally on the plant.
CBD (Cannabidiol) is the result of heating extracted substances CBDA (Cannabidiolic Acid) from the Cannabis / Hemp plant. CBD Oil is the most common form of product available for retail purchase, and can be made from Isolate mixed with carrier oils, or extracted directly from plant materials using critical extraction or distillation processes.
Most “50 State Legal” CBD is derived from those parts of the (edit:IMPORTED) Cannabis / Hemp plant set aside in the 2004 settlement ruling between DEA & HIA. This means (edit:IMPORTED sludge-like oil from FOREIGN) stalks, fiber and hemp-hurd.
HEMP-X is grown by Native Americans.
