Editorial policy

Each page answers the question a reader actually has (“does ginger help nausea?”) in the first two sentences, then shows the evidence claim by claim, the amounts studied, who should avoid it and the medicine interactions. Every page is written by hand; nothing is generated from a template of stock phrases.

• Systematic reviews and meta-analyses, including Cochrane reviews, then individual randomized trials, all found through PubMed.
• Government sources: NIH Office of Dietary Supplements, NCCIH, FDA, MedlinePlus, and the National Center for Home Food Preservation for food safety.
• Clinical guidelines from professional bodies where a page touches on a condition.

Every PubMed ID is checked against the PubMed record before publication, and every number on a page comes from the cited abstract or source. If we cannot find a source for a figure, the figure is left out.

We follow the spirit of the FDA and FTC rules on health claims. No page says a food or herb cures, treats or prevents a disease. We describe study results (who took what, and what changed), grade them on the four-step scale, and point readers with a condition to their clinician.

Affiliate relationships are described on how we make money. They never decide a grade, and no company reviews a page before publication.

Every page shows the date it was last reviewed. When new research changes the picture, or a reader points out an error, we update the page and the date. Send corrections, ideally with the study, through the contact form.
