A Randomized, Double-Blind, Dual-Control (Internal and External) Clinical Study of Ning Shen Dan Xiang Gao Fang in the Treatment of Insomnia (Heart-Kidney Disharmony Type)

The goal of this clinical trial is to learn if Ning Shen Dan Xiang paste combined with Ejiao (donkey-hide gelatin) works better than Ning Shen Dan Xiang paste combined with agar (placebo substitute) to treat chronic insomnia of the heart-kidney disharmony type in adults. It will also assess safety. The main question is:

- Does Ning Shen Dan Xiang + Ejiao improve sleep quality more than the placebo version, as shown by the change in Pittsburgh Sleep Quality Index (PSQI) score after 8 weeks?

Researchers will compare the two pastes (identical in appearance and taste except for Ejiao) and use published literature data as an additional external control.

Participants will:

Take 20 g of the assigned paste twice daily (morning and evening) for 8 weeks. Attend clinic visits at baseline, week 4, week 8, and 1 week after stopping (week 9 follow-up).

Complete PSQI and ISI questionnaires, keep a daily electronic sleep diary, provide blood/stool samples, and undergo safety monitoring (blood/urine tests, ECG, vital signs, and side effect checks).
