due to synergism

The clinical trial studied the synergism between hormones and the prescription drugs.

Adherents of religious synergism suggest that believers must cooperatively determine their own destiny.

Hormone synergism happens and produces results greater than the individual effects of the hormones involved.

One term for it is potentiation.

drug synergism is when you mix together two or more drugs, such as wine, beer, pills, crap, and pot. when any of these drugs mix with another you get very high and results could be deathly.
