Commercial Chinese polyherbal preparations combined with conventional therapy improve sleep quality in elderly patients with insomnia
A network meta-analysis of 19 RCTs involving 1851 participants found that commercial Chinese polyherbal preparations combined with conventional therapy significantly reduced PSQI scores (MD = -2.53, 95% CI [-3.62, -1.44]) and increased clinical effective rate (OR = 6.08, 95% CI [3.21, 11.51]) compared to conventional therapy alone. The evidence for effects on serum IL-6 was exploratory and limited.

The Claim
Commercial Chinese polyherbal preparations combined with conventional therapy improve sleep quality in elderly patients with insomnia
This conclusion is most relevant to: Elderly patients aged ≥60 years with insomnia.
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸A network meta-analysis of commercial Chinese polyherbal preparations for insomnia in the elderly: focusing on sleep quality and the neuro-immune axis. (Frontiers in pharmacology, 2026) —
How It Works
The proposed biological pathway:
- ▸Chinese herbal preparations may modulate the neuro-immune axis
- ▸Reduction in serum IL-6 levels suggests anti-inflammatory effects
- ▸Decreased neuroinflammation may improve sleep quality
- ▸Result: Improved PSQI scores and clinical response
Who Might Benefit
Evidence fit by population:
- ▸Elderly patients aged ≥60 years with insomnia
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Risk of bias in included studies, particularly regarding blinding and outcome measurement
- ▸Small number of studies for IL-6 analysis limits certainty of mechanistic findings
Frequently Asked Questions
What is the primary benefit of commercial Chinese polyherbal preparations for elderly insomnia?▼

How large is the effect on PSQI score?▼
The mean difference was -2.53 points, indicating a clinically meaningful improvement.
Do these preparations affect inflammatory markers?▼
There is a preliminary trend toward reducing serum IL-6, but evidence is limited by few studies.
What is the recommended treatment duration?▼
The abstract does not specify a duration; it varies across the included RCTs.
