Both CBD and CBDA are cannabinoids found naturally in cannabis and hemp plants that interact very well with our own endocannabinoid body systems.
During the plant growing cycle there are many chemical changes that result in the production of different cannabinoids.  CBDA is often referred to as the “raw” or “acidic” form and is found in much higher concentration on the live plant than CBD.  This is because CBDA is the chemical precursor to CBD and will turn into CBD through a process called “decoxylation” through heat, time and oxygen exposure.
It used to be believed that this acidic form needed to be “activated” and turned into CBD to unlock its therapeutic benefits, but this has been proven to be completely false.  This myth most likely began because it was associated with THCA and THC, where you only felt the “high” of THC when THCA was decarboxylated.  The acidic cannabinoids (CBDA, THCA, CBGA, etc) have all been proven to have extremely powerful therapeutic benefits in their own right, sometimes even more so than their decarboxylated counterparts.
