Research Library
The research we read, listed in full with its sources. Some of it is peer-reviewed, some is a university extension note, some is a magazine feature or a summary we wrote ourselves — each entry says which, because the difference matters when you are deciding how much weight to give it.
Every item links to the publisher rather than a copy hosted here, so you are reading the version of record.
Cannabinoids and cancer
Five of these six come from the same group — Katherine Scott, Wai Man Liu and Professor Angus Dalgleish at St George's, University of London. They are laboratory and animal studies about how cannabinoids behave alongside chemotherapy and radiation. None of them is a study of an Oley product, and none of them is a human clinical trial of a consumer product.

About Professor Dalgleish
Angus Dalgleish is a British oncologist and immunologist, Foundation Chair in Oncology at St George's, University of London and now Professor Emeritus. His research has centred on cancer vaccines and immunotherapy, cytokine biology, melanoma and renal-cell cancer. Profiles: City St George's · ICON Cancer Centre.
Cannabinoids and Alzheimer's disease
- University of the Basque Country, reported by ScienceDaily, 15 January 2025 — a rodent study of cognitive improvement in early Alzheimer's disease. Worth reading carefully: the compound studied is WIN55,212-2, a synthetic cannabinoid-receptor agonist. It is not CBD, and it is not an ingredient in anything we sell.
Honey and nasal allergy
- Ditzel AN. Is honey, as adjunctive therapy, effective in alleviating nasal allergy symptoms? Philadelphia College of Osteopathic Medicine, 2019. A Physician Assistant Studies student systematic review, openly published on DigitalCommons@PCOM — a student capstone paper rather than a peer-reviewed journal review.

- Waters J. Does nitric oxide = qi? Acupuncture Today, "East Meets West" column. A practitioner opinion piece drawing correspondences between qi and nitric oxide — interesting framing, not evidence.
- West S. The link between qigong breath holding and nitric oxide. Pacific College of Health and Science, 26 March 2020. A college blog post.
- A reading list of topical-CBD studies we keep for reference: analgesic and anti-inflammatory effects of 1% topical CBD gel in animal models; transdermal CBD in a rat model of arthritis; topical CBD tolerability in people with chronic lower-extremity pain; topical cannabidiol and the skin.
Our own summaries
Two documents in this collection were written in-house rather than published. They are background notes, and we list them so the collection is complete.
- Nitric oxide: key ideas — a structured summary of a recorded interview covering nitric oxide biology, the dietary nitrate pathway, oral bacteria, ageing and exercise. It is a summary of one conversation, not an independent review. The readable version of the parts that are settled science is on our How the Products Work page.
- Nitric oxide in dermatology — notes on how nitric-oxide-releasing topicals are described in the dermatology literature. Important context: much of the clinical evidence it describes concerns berdazimer sodium, a prescription medicine approved for molluscum contagiosum. That is a regulated drug, not a cosmetic, and nothing in those findings describes an Oley product or transfers to one.
Hemp, soil and feed
One distinction governs this whole section: industrial hemp and sunn hemp are different crops. Industrial hemp is the one relevant to soil function and nutrient capture; sunn hemp is used for summer forage and grazing.
- Evaluating the effects of industrial hemp cultivation on soil quality in Florida — peer-reviewed journal article. Supports cautious statements about soil organic matter and nitrate-N reduction, with outcomes management- and site-dependent.
- Industrial hemp — Penn State Extension. Soil suitability, drainage and compaction sensitivity.
- Sunn hemp can boost summer pastures — University of Missouri Extension. Summer forage and grazing management. Note that sunn hemp seeds are toxic to cattle.
How to read this collection
Almost everything here is laboratory work, animal work, or a review of other people's work. That is the honest state of the evidence, and it is why this page exists separately from anything describing a product.
This page is a bibliography, published for transparency about what we read. It is not medical advice, none of it is a claim about any Oley product, and no Oley product is intended to diagnose, treat, cure or prevent any disease. Speak to a qualified healthcare professional before starting any new wellness regimen, particularly if you have a medical condition, are pregnant or nursing, or take medication.
