How Does CBD Compare To Whole Plant Extracts?
As we’ve learned over the past dozen years of reading about nutrition and human health, whole foods tend to be more effective than isolated components. Whole foods have several advantages. They contain all the components related to the compound, especially the ones we haven’t discovered and isolated. Supplements only contain the isolated compounds we’ve been able to quantify. Whole foods also capture all the synergistic effects of the multiple components working together. Isolated supplements miss that synergy unless they specifically add it back in, and even then they’ll probably miss something.
It’s likely that whole plant hemp extracts high in CBD are superior to isolated synthetic CBD for the same reason. Is there any evidence of that?
A high-CBD cannabis whole plant extract reduces gut inflammation and damage in a mouse model of inflammatory bowel disease. Purified CBD does not.
Even at a 2:1 CBD:THC ratio, co-ingesting isolated CBD with isolated THC using a vaporizer fails to reduce the psychotic and memory-impairing effects of THC. In another study, however, smoking cannabis naturally rich in both CBD and THC completely prevented the memory impairment.
And as we saw in the pain section above, THC combined with CBD seems more effective against pain than either alone.
That’s not to say isolated (even synthetic in some cases—see note below) CBD isn’t helpful. We saw it improve joint pain and reduce nerve damage in arthritic rats. It’s just that full-spectrum hemp oil containing multiple naturally-occurring compounds is probably ideal for general health applications. Specific conditions requiring high doses may be another question entirely. Again, we’ll find out as more research comes out.
A word about synthetics: this is fodder for a follow-up, but it appears there may be additional concerns with synthetic CBD, and even supposedly “natural” CBD companies have in some cases allegedly added ingredients to their formulas without letting consumers know.
