The Entourage Effect
Raphael Mechoulam First described in 1998 by Israeli scientists Shimon Ben-Shabat and Raphael Mechoulam,
the basic idea of the entourage effect is that cannabinoids within the cannabis plant work together, or possess synergy,
and affect the body in a mechanism similar to the body’s own endocannabinoid system.
This theory serves as the foundation for a relatively controversial idea within pharmacology community, that in certain
cases whole plant extractions serve as better therapeutic agents than individual cannabinoid extractions.
The entourage effect theory has been expanded in recent times by Wagner and Ulrich-Merzenich, who define the four
basic mechanisms of whole plant extract synergy as follows:
Ability to affect multiple targets within the body
Ability to improve the absorption of active ingredients
Ability to overcome bacterial defense mechanisms
Ability to minimize adverse side effects.
Many studies have demonstrated the effectiveness of cannabis as a therapeutic agent for muscle spasms associated
with multiple sclerosis. A study conducted by Wilkinson and colleagues determined that whole-plant extracts were more
effective than THC alone.
Researchers compared 1mg THC vs. 5mg/kg cannabis extract with the equivalent amount of THC, and found the whole
plant extract to have significantly more antispastic effect.
The researchers attributed this result to the presence of cannabidiol (CBD) within the cannabis extract, which helps to
facilitate the activity of the body’s endocannbinoid system.
Improving Absorption Of Active Ingredients
The entourage effect can also work to improve the absorption of cannabis extracts. Cannabinoids are chemically polar
compounds, which makes them at times makes them difficult for the body to absorb in isolation.
“With the assistance of terpenoids like caryophyllene, absorption of cannabinoids can be increased.”
Absorption of topicals provides a prototypical example of this problem. The skin is made up of two layers, also known
as a bi-layer, which makes it difficult for for very polar molecules like water and cannabioids to pass through.

The entourage effect also accounts for cannabis extracts to be effective in treating various bacterial infections.
There are a number of studies which show the antibacterial properties of cannabinoids.
“Whole-plant cannabis extracts have non-cannabinoid constituents which also have antibacterial properties.”
However, bacteria develop defense mechanisms over time to combat the effects of antibiotics ultimately allowing them to
become resistant to therapies which were previously effective.
Thus, it is beneficial that whole-plant cannabis extracts have non-cannabinoid constituents that also have antibacterial
properties. These molecules attack bacteria through pathways which differ from cannabinoid pathways. Given the attack
on multiple fronts, the development of bacterial resistance is limited.
Minimizing Adverse Side Effects
Finally, the entourage effect allows certain cannabinoids to modulate the negative side effects of other cannabinoids.
The most fitting example of this is CBD’s ability to modulate the perceived negative effects of THC.
Many patients have heard about (or experienced) the increased anxiety and paranoia sometimes associated with cannabis
consumption. Thanks to the entourage effect, research has shown that CBD can be effective in minimizing the anxiety
associated with THC, lowering users’ feelings of paranoia.
As you can see, THC, CBD, and the remaining cannabinoids don’t have to compete with one another – they can work in
tandem alongside the other components of cannabis extracts to provide therapeutic relief for a wide variety of ailments.
