Our methodology

← Home

How we decide what this library says, what our grades mean, and what we do not cover. If you are a journalist or a clinician checking our work, this page is the place to start — including the parts that are not flattering.

Who reviews this, and what they are qualified to say

Everything here is reviewed by the HealisticMD editorial team. Accountability is organisational, not personal.

HealisticMD has no clinician on staff and does not give medical advice.

The editorial team is responsible for

  • The evidence grading scheme and every grade assigned under it
  • Which sources are admitted to the citation index
  • Approving each condition's recommendation set before it reaches the quiz
  • Approving every safety and drug-interaction statement

That is the whole list. No clinician is on staff — so no page here claims to have been medically reviewed. Where a specific entry has had human review, the reasons are set out under “How entries are written and checked” below.

The review process, in order

  1. Retrieval first. Before anything is written, the published literature for that remedy is retrieved and indexed — PubMed for trials and systematic reviews, and the tradition’s own canonical texts for traditional use. The draft is written against what came back. Nothing is drafted and then given citations to match, which is the ordering that produces claims the sources do not carry.
  2. Round one — structure and completeness. Required safety fields, dosage, interactions and the traditional record must all be present, and every citation must resolve to a real record. A draft missing any of them is not published.
  3. Round two — independent claim check. A second model, which has not seen the first one’s reasoning, reads the draft against its sources and flags anything asserted more strongly than the evidence supports. Disagreements go to human review rather than to a tie-break.
  4. Round three — grading. The evidence grade and the traditional tier are assigned separately, against the published record only. A grade is never raised because a remedy is popular or widely used.
  5. Human review, where it matters most. Entries involving higher-risk substances, drug interactions, pregnancy or children are read by a person before publication. Routine entries are sampled. We would rather state that plainly than imply every page has been individually read.
  6. Publication gate. An entry that does not say what it is for is held rather than published, because a remedy with no condition association cannot be checked against anything.

The grading scheme itself is set out below, and every grade we have assigned is listed with its counts in the evidence report — including how much of the library sits at the bottom of the scale.

Two things are graded, separately

Most natural-health sites collapse “people have used this for a long time” and “this has been shown to work” into a single verdict. Those are different claims and we grade them on two independent axes, so a remedy can be a classical staple with almost no trial evidence, and we will say exactly that.

Evidence grade

What the published human research supports. We call it an evidence grade, not a clinical grade, because it grades literature — we are a content library, not a clinic, and this is not a clinician’s assessment of you.

A:
Supported by controlled trials in this condition.
B:
Supported by smaller or mixed clinical studies.
C:
Limited or preliminary clinical evidence.
D:
Mechanism or laboratory evidence only — no useful human data.

A grade is not a recommendation, and a higher grade does not mean a remedy will work for you. Many entries are ungraded, which means we have not assessed the literature yet — not that evidence is absent.

Traditional use

Classical:
Recorded use across multiple traditions over centuries.
Established:
A long-standing staple of at least one tradition.
Peripheral:
Used, but not a core part of any tradition's canon.
No traditional record:
Rendered as nothing at all, rather than as a claim of absence.

Traditional standing is a historical fact about practice. It is never evidence of safety or of effect, and we do not present it as either.

Citations

Where we cite a study we cite a PubMed identifier, and every identifier is resolved against PubMed before it is published — a citation that does not resolve is removed rather than reworded. We check the publication year against what our own text claims, because a real identifier attached to the wrong claim is still wrong.

Where we could not find human research, the page says so in plain words instead of describing studies in the abstract. “No human trials specific to this have been published” is a useful answer.

Safety information

Every entry carries a safety review. Pages show who should avoid it as direct instructions, and when to see a doctor with the specific symptoms that warrant it. Entries that can cause serious harm are held to a stricter standard, and for restricted or toxic substances we deliberately publish no dose, preparation method or source — the page explains the risk and points to safer options instead.

We publish pages on dangerous substances rather than omitting them. People search for them precisely because they are dangerous, and an honest page is more useful than whatever else they would find.

How entries are written and checked

Entries are drafted with AI assistance and then put through automated checks before publication: the structure and required safety fields must be complete, every citation must resolve, claims are reviewed by a second independent model for anything stronger than the evidence supports, and the writing must meet a plain-language reading standard. A draft that fails any of these is not published until it passes.

Entries involving higher-risk substances, drug interactions, pregnancy or children receive human review. Routine entries are sampled rather than individually read. We would rather state that plainly than imply a clinician has read every page.

What we do not do

  • We do not give medical advice, and nothing here is a diagnosis.
  • We do not claim anything cures a condition, and we do not promise outcomes.
  • We do not rank remedies commercially. Where products appear, inclusion is never sold, and affiliate links are disclosed where they exist.
  • We do not present traditional use as proof, or an ungraded entry as an endorsement.

Corrections

If something here is wrong, we want to know and we will fix it. Use the contact page, and tell us which entry and what is wrong with it. Corrections to safety information are treated as urgent.
