Evidence Must Match the Claim
A citation is useful only when it supports the intervention, product, population, protocol, and outcome being described. Adding a research link does not make a broad marketing claim accurate.
We avoid transferring evidence from a licensed clinical procedure to a differently designed consumer product. We also avoid using a proposed biological mechanism as proof that a visible or medical result occurred.
Source Hierarchy
Depending on the question, we generally prefer:
- systematic reviews and meta-analyses relevant to the exact intervention;
- randomized or controlled studies using a comparable protocol;
- regulatory documents and official device labeling;
- clinical reference material from recognized public or academic institutions;
- manufacturer manuals for specifications and contraindications;
- observational, exploratory, survey, or mechanistic studies presented with their limitations.
Testimonials, retailer descriptions, influencer content, and seller-created diagrams may describe marketing or user experience, but they are not substitutes for controlled evidence.
Product-Specific Translation
Before applying a study to a consumer product, we ask whether it used:
- the same manufacturer and model;
- the same output, dose, wavelength, pressure, frequency, or waveform;
- the same treatment duration and schedule;
- the same body area and health goal;
- a comparable population and control group.
If those details differ, the source may provide background but not product proof.
Traditional Medicine Language
Traditional Chinese Medicine concepts may be discussed as historical, cultural, or practitioner frameworks. We do not translate qi, meridians, blood stasis, dampness, or deficiency into diagnosed blood-flow, nerve, fascia, lymph, hormone, immune, or cellular conditions.
A traditional description cannot establish that a retail tool detects an organ problem, locates an unhealthy acupoint, clears a blockage, or produces a measured biological change.
Claims We Treat With Extra Caution
Claims involving disease treatment, pain, neuropathy, circulation, lymph drainage, detoxification, inflammation, hormones, immunity, sleep, hair growth, collagen, cellular energy, ATP, tissue repair, or accelerated recovery require especially close matching between source and statement.
Softening a verb to “support,” “promote,” “encourage,” or “assist” does not solve an evidence problem.
Regulatory Wording
“FDA registered,” “made in an FDA-registered facility,” “FDA cleared,” and “FDA approved” are not interchangeable. When a regulatory statement matters, we seek the exact device identifier and authorized intended use. Clearance for one indication does not support unrelated claims.
Citations on the Site
Article references appear in a dedicated source section and are included in Article structured data. Topic guides include sources that clarify the scope and limits of their decision frameworks.
External sources can change or disappear. Broken, retracted, mismatched, or materially revised sources should be reported through our Corrections Policy.
Uncertainty Is Part of the Answer
When evidence is limited, mixed, indirect, or unavailable for the exact product, we say so. The appropriate conclusion may be that only the physical operation, safety information, and buying factors can be described confidently.
