A mouse experiment found prolonged pentobarbital-induced sleep with selected extracts. Antagonist results suggested more than one possible pathway rather than a pure benzodiazepine-like effect.
The researchers tested fruit or seed preparations of Lagenaria vulgaris and fruit preparations of Cucurbita pepo. Several preparations prolonged pentobarbital sleep, with seed extracts showing effects at lower tested doses.
Flumazenil reversed selected extract effects, and naloxone also reversed effects of Lagenaria seed preparations. Cell-viability tests did not identify toxicity under the tested conditions.
The experiment used injected preparations before a barbiturate challenge rather than oral treatment of spontaneous insomnia in people. Antagonist sensitivity supports pathway involvement without proving direct binding to a unique receptor site.
The findings cannot establish a safe human dose or safety of mixing extracts with sedatives. Limited cell tests do not cover systemic or chronic toxicity. A faithful account retains extract method, plant part, challenge drug, and endpoint rather than presenting traditional products as clinically validated benzodiazepine replacements.
