Black seed oil extracts are being explored for sleep quality. A short trial of a proprietary preparation measured sleep using both a wearable device and a questionnaire.
Study design
Randomised, double-blind, placebo-controlled study; 70 adults; proprietary BCO5 extract, 200 mg daily; seven days; actigraphy and questionnaire outcomes.
Reported findings
A published study randomised 70 adults with non-restorative sleep to a proprietary black cumin oil extract, BCO5, or placebo for seven days. It reported improvements using actigraphy and a questionnaire. The paper declared commercial connections relevant to the product.
Interpreting the result
This was a very short study of a proprietary preparation. The paper declares commercial connections. It does not establish long-term effectiveness for chronic insomnia or demonstrate the same effect from an ordinary retail oil.
Why this study is useful
The study used BCO5, a proprietary extract, and lasted seven days. Its findings concern that preparation and short-term sleep measurements. The paper also reports commercial connections. Longer, independently replicated studies would help establish how broadly the findings apply.
