Isolate

A single purified cannabinoid, typically 99%+ pure, with nothing else present.

Epidiolex is effectively a pharmaceutical-grade CBD isolate, and its RCT evidence in specific seizure disorders shows isolates can be highly effective.

Isolate is the right choice when you need a known quantity of one compound and nothing else — for drug-testing reasons, or to avoid THC entirely.

Also written as: cbd isolate, thc isolate.
