The entourage effect describes the phenomenon in which various cannabis ingredients, particularly cannabinoids and terpenes, work together synergistically. This means that the combined effect of these substances is greater than the sum of their individual effects. The effect occurs because cannabinoids and terpenes together activate and modulate the receptors in the human body in a more complex way than isolated substances. This results in a richer and potentially more effective therapeutic effect. The entourage effect is often cited as a reason why full-spectrum cannabis products can be more effective than isolated cannabinoids.
