NCT07788547

Brief Summary

The goal of this clinical trial was to determine whether nightly exposure to a Traditional Chinese Medicine herbal sachet could reduce insomnia symptoms and improve sleep quality in adults aged 60 years or older. Participants residing in five community-based integrated medical and elderly-care facilities in Qingdao, China, were assigned by chance to receive either the herbal sachet or a placebo sachet. Participants placed the assigned sachet within 30 centimeters of the head from 7:00 p.m. to 8:00 a.m. each night for eight weeks. Insomnia symptoms and sleep quality were assessed using the Athens Insomnia Scale and Pittsburgh Sleep Quality Index. Adverse reactions were monitored throughout the intervention

Outcome Measures

Primary Outcomes (1)

  • Pittsburgh Sleep Quality Index (PSQI) Total Score

    The PSQI assesses sleep quality during the previous month. It contains 19 self-rated items and 5 other-rated items. Eighteen self-rated items produce 7 component scores: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleep medication, and daytime dysfunction. Each component is scored from 0 to 3, producing a total score from 0 to 21. Higher scores indicate poorer sleep quality.

    Baseline (Day 1), Day 28, and Day 56

Secondary Outcomes (1)

  • Athens Insomnia Scale (AIS) Total Score

    Baseline before intervention, Day 28, and Day 56

Study Arms (2)

Traditional Chinese Medicine Herbal Sachet

EXPERIMENTAL

Participants received usual sleep-related care plus a 100-g compound traditional Chinese medicine herbal sachet. The sachet was placed beside the pillow within 30 cm of the participant's head from 7:00 p.m. to 8:00 a.m. every night for 8 weeks. Sachets were collected and sealed each morning and replaced every 2 weeks.

Other: Traditional Chinese Medicine Herbal Sachet

Placebo Herbal Sachet

PLACEBO COMPARATOR

Participants received the same usual sleep-related care and schedule using a 100-g placebo herbal sachet. The placebo sachet had the same packaging as the experimental sachet but contained a different herbal mixture considered not to affect sleep. Sachets were placed within 30 cm of the participant's head from 7:00 p.m. to 8:00 a.m. every night for 8 weeks and replaced every 2 weeks.

Other: Placebo Herbal Sachet

Interventions

Each 100-g sachet contained powdered Suan Zao Ren, Cao Jue Ming, Jiang Xiang, Ye Jiao Teng, Yuan Zhi, rose flower, jasmine flower, He Huan Pi, Mu Xiang, and Chen Xiang. The ingredients were powdered to 80-100 mesh, uniformly mixed, and sealed in a nonwoven inner bag with a linen outer bag. One sachet was used nightly for 8 weeks and replaced every 2 weeks.

Traditional Chinese Medicine Herbal Sachet

Each 100-g placebo sachet contained Huo Xiang 15 g, Bai Zhi 15 g, Ge Gen 30 g, Che Qian Cao 18 g, and Fu Hai Shi 22 g. The ingredients were powdered to 80-100 mesh and packaged in the same manner as the experimental sachet. One sachet was used nightly for 8 weeks and replaced every 2 weeks.
