Quantifying the effects of mild sedatives.

P D Leathwood, F Chauffard

    Journal of Psychiatric Research
    |January 1, 1982
    PubMed
    Summary

    Valeriana officinalis L. extract shows mild sedative effects, improving sleep quality subjectively. While physiological measures like sleep latency showed trends, they lacked statistical significance in this study.

    Area of Science:

    • Pharmacology
    • Sleep Medicine
    • Herbal Medicine

    Background:

    • Quantifying mild sedative effects requires assessing both physiological and subjective sleep parameters.
    • Valeriana officinalis L. is a commonly used herb with purported mild sedative properties.

    Purpose of the Study:

    • To evaluate the sedative effects of a 400 mg aqueous extract of Valeriana officinalis L.
    • To compare subjective self-reported sleep quality with objective physiological sleep measures.

    Main Methods:

    • Subjective assessment using a questionnaire to evaluate perceived sleep latency, awakenings, and sleep quality.
    • Objective assessment using electroencephalography (EEG) to measure sleep latency and awakenings.

    Main Results:

    • Subjective analysis indicated the Valeriana officinalis L. extract significantly reduced perceived sleep latency and night awakenings, improving sleep quality.
    • EEG study showed trends towards shorter mean sleep latency and increased latency to first awakening, but these changes did not reach statistical significance.

    Conclusions:

    • The study highlights the importance of integrating subjective and objective data when evaluating mild sedatives.
    • Valeriana officinalis L. extract demonstrated promising subjective sedative effects, warranting further investigation with larger sample sizes or refined methodologies.
