Sleep disorders and non-drug options: what a 2025 TCM fumigation and Acanthopanax study adds, and where the Lingshū's rhythm language fits

For most people, poor sleep is not simply a matter of "not getting enough hours." Late-night screen use, rotating shift schedules, daytime reliance on caffeine, and irregular bedtimes are common modern habits that can disrupt the body's internal day-night rhythm, often called the circadian rhythm. Classical medical literature had already described this kind of state, in which a person cannot sleep when they should and cannot wake when they should. One passage from the Lingshū puts it this way: "Defensive qi normally moves through the yang during the day and through the yin at night; when the yang is exhausted one sleeps, and when the yin is exhausted one wakes." The ability to fall asleep, in this framing, is a sign that the body has completed its daily transition from yang back into yin.

A second Lingshū passage addresses sleeplessness more directly: "When defensive qi cannot enter the yin and remains in the yang, the yang becomes full; when the yang is full the yang qiao vessel is exuberant; and because it cannot enter the yin the yin becomes deficient, so the eyes do not close." In other words, insomnia is described as a failure of qi to shift from yang into yin at the right time. The text treats sleep as the visible outcome of a circulation pattern, and sleeplessness as the visible outcome of that pattern being stuck. A third passage, from a different chapter of the Lingshū, lists the origins of illness broadly: "All illness arises from wind, rain, cold, and heat; from the yin-yang balance of joy and anger; from diet and dwelling; and from great fright or sudden fear." External weather, internal emotion, daily routine, and living conditions are placed on the same list. That outlook matches what modern sleep medicine calls sleep hygiene: the idea that the conditions of daily life shape how well a person sleeps.

On the polysomnography recordings, sleep structure indicators in the study group also moved more favorably than in the control group, suggesting that the change was not only subjective but also visible in the objective staging of sleep. On the GQOLI-74 quality-of-life scale, the study group again outperformed the control group, which suggests that the sleep improvement carried over into daytime function and overall well-being.

Adverse events were tracked alongside these outcomes. The authors describe the combined therapy as well tolerated, and they characterize it as an effective, well-tolerated, and non-invasive adjunct. They specifically note that patients with poor tolerance to hypnotic medications, and those whose insomnia is related to stress, may be particularly suitable candidates. Taken together, the abstract describes a consistent pattern across all three measurement domains, with the study group outperforming the control group on subjective sleep quality, objective sleep structure, and quality of life, and with an acceptable safety profile.

What makes this study interesting from the perspective of the Lingshū is the choice of intervention. TCM fumigation and washing delivers herbal compounds through the skin, and Acanthopanax senticosus injection delivers an extract into the bloodstream, so the combined therapy works on the body surface and on internal circulation at the same time. The aim, as the authors describe it, is to support the body's response to stress and to its daily rhythm rather than to suppress the central nervous system directly. That framing echoes the Lingshū image of "defensive qi not entering the yin and remaining in the yang," in which long periods of stress or irregular routine leave the body stuck on the yang side of its cycle and unable to cross over into sleep. The interventions in this study, in other words, are attempting to recreate the conditions under which that crossing becomes possible again.

It is important, however, to keep the two frameworks clearly separated. PSQI and polysomnography measure constructs defined by modern sleep medicine, including self-rated sleep quality and the architecture of sleep stages as recorded by electrodes. The Lingshū uses the language of defensive qi, yin and yang, and the yang qiao vessel to describe a similar phenomenon in a different conceptual vocabulary. Saying that the two describe the same mechanism would be a category mistake: the study can be read alongside the classical passages, but the statistics cannot prove the classical theory, and the classical theory cannot validate the statistics. For an ordinary reader, the practical takeaway is that this study adds to a growing case that non-drug options deserve attention, while decisions about any individual course of care still belong in a clinical evaluation that takes personal routine, stress level, and medical history into account.

Even though the abstract describes the combined therapy as effective, well tolerated, and non-invasive, the authors themselves call for further prospective randomized trials with longer follow-up to confirm long-term efficacy. That call marks the boundary of what the current data can support. Several questions remain open. It is not yet known how long the benefit lasts after treatment stops, how the intervention performs across different age groups and in patients with other medical conditions, how it interacts with other sleep medications, what the optimal herbal composition and injection dose are, and how it compares with other non-drug options such as cognitive behavioral therapy for insomnia.

It is also worth noting that this is a single-center retrospective analysis of 106 patients, and the abstract does not describe the group assignment as randomized. Under those conditions, the result is best read as a promising direction that warrants further study rather than as a treatment guideline that can be applied directly. Readers should be cautious about treating any single clinical result as definitive, and should not view TCM fumigation as an independent replacement for standard medical care.

When people ask what non-pharmacological options exist for improving sleep quality, the answers are usually familiar: keeping a regular schedule, limiting screens before bed, moderating caffeine, and building wind-down habits. These are the everyday rhythm-related choices that sleep medicine has long emphasised. The study we are reading here, however, adds another layer to that conversation. Published on 2025-11-01, it is a clinical report titled "Efficacy of fumigation with traditional Chinese medicine combined with Acanthopanax Senticosus injection in patients with sleep disorders." Its objective, stated plainly in the abstract, was to evaluate the efficacy of traditional Chinese medicine (TCM) fumigation and washing combined with Acanthopanax senticosus injection in patients with sleep disorders.

To understand what the researchers actually did, it helps to unpack three tools. The Pittsburgh Sleep Quality Index, or PSQI, is a widely used questionnaire that asks about recent sleep habits—how long it takes to fall asleep, how many hours a person actually sleeps, how often they wake, and how rested they feel the next day; lower scores mean better sleep. Polysomnography, abbreviated PSG, is an overnight recording done in a sleep lab, where electrodes track brain waves, breathing, and blood oxygen to map out how much deep sleep, light sleep, and REM sleep a person gets. The GQOLI-74 scale is a quality-of-life instrument covering physical, psychological, and social functioning. Putting these instruments together allowed the team to look at sleep from both subjective and objective angles.

The methodology was a retrospective review of 106 patients with sleep disorders treated at Yan'an Traditional Chinese Medicine Hospital from January 2023 to January 2025. Patients were divided into two groups: the control group (n=51) received routine care with dexzopiclone, a hypnotic medication; the study group (n=55) received additional TCM fumigation and Acanthopanax senticosus injection. Safety indicators and adverse events were also recorded alongside the main outcomes.

The abstract reports that after the intervention, the study group showed significantly greater improvements in PSQI scores compared to the control group. The authors' conclusion is that TCM fumigation and washing combined with Acanthopanax senticosus injection may serve as an effective, well-tolerated, and non-invasive therapy for improving sleep quality and life quality in patients with sleep disorders. They also suggest the therapy may be particularly beneficial for individuals with poor tolerance to hypnotic medications or stress-related insomnia, while calling for further prospective randomized trials with longer follow-up to confirm long-term efficacy.

For the curious reader, the practical takeaway is twofold. First, this single retrospective study points to a non-drug adjunct worth further investigation, especially for those who struggle with standard hypnotics. Second, the meaningful boundary here is interpretive: a single clinical report cannot be treated as a confirmed treatment guideline, and TCM fumigation should not be regarded as a standalone replacement for standard medical care. Whether someone explores such an option should be a conversation with a qualified clinician, set against the everyday rhythm habits that the classical texts and modern sleep medicine both emphasise.
