More About Azulene
These chemicals are considered contaminants of CBD distillate. To prevent these molecules from corrupting the distillate, the manufacturer makes sure they don’t “sneak” in the main distillate in the first place. They carefully collect the distilled fractions to avoid this from happening. If these molecules get into the distillate, then the manufacturer removes them before applying any heating processes to the extract.
