Why we cite our sources

Health and wellness content (what Google calls “YMYL”, Your Money or Your Life) is held to a higher standard than ordinary editorial. Citations are the simplest form of accountability, the reader can see exactly where each claim comes from, and decide for themselves how strong the evidence is.

Our hierarchy: Tier 1 is peer-reviewed clinical research from PubMed, NCCIH, NIH, Memorial Sloan Kettering, and Cochrane Reviews. Tier 2 is canonical herbal-medicine sources, the Bach Centre and Bach Flower (for flower-essence work), Chestnut School of Herbal Medicine (where Gaia trained as a clinical herbalist), and the American Botanical Council. Tier 3 is mainstream medical references like Mayo Clinic and Cleveland Clinic, used only when they themselves cite Tier 1.

A note on what citations mean (and what they don’t)

Citing a study does not mean we are claiming our products treat or cure the conditions the study examines. It means a credible researcher has investigated the herb, the preparation, or the pathway we are writing about, and the reader is welcome to read the original work and form their own picture.

The clinical herbalism Gaia practices is structure-and-function support for healthy people, not diagnostic medicine. Always consult your physician before starting an herbal protocol if you are pregnant, nursing, taking prescription medications, or managing a chronic condition.
