What does “Broad-spectrum” mean?

A preparation containing a range of plant compounds but with one component, usually THC, removed or reduced.

Broad-spectrum in plain English

A preparation containing a range of plant compounds but with one component, usually THC, removed or reduced.

As with full-spectrum, the term is a commercial description rather than a regulated definition, and what it means in practice varies between suppliers.

Removal of THC is never absolute. Products described as THC-free have been found on testing to contain detectable amounts, which can matter for workplace drug testing.
