Scientific Information on Erythema


Human Effect Matrix

The Human Effect Matrix looks at human studies (it excludes animal and in vitro studies) to tell you what supplements affect erythema
Grade Level of Evidence
Robust research conducted with repeated double-blind clinical trials
Multiple studies where at least two are double-blind and placebo controlled
Single double-blind study or multiple cohort studies
Uncontrolled or observational studies only
Level of Evidence
? The amount of high quality evidence. The mo re evidence, the more we can trust the results.
Outcome Magnitude of effect
? The direction and size of the supplement's impact on each outcome. Some supplements can have an increasing effect, others have a decreasing effect, and others have no effect.
Consistency of research results
? Scientific research does not always agree. HIGH or VERY HIGH means that most of the scientific research agrees.
Notes
grade-c Feverfew Notable - See study
The reduction in erythema with topical parthenolide-depleted feverfew was greater than that of the active control, Ibuprofen.
grade-c Fish Oil Minor Very High See 2 studies
Ingestion of fish oil appears to prolong the time required for sunlight to induce reddening of the skin, and secondary to this fish oil ingestion above 1,800mg EPA is able to reduce the risk of sunburn.
grade-c Vitamin E Minor Very High See 2 studies
Topical application of vitamin E to scar tissue has, in some participants, caused significant increases in redness of the tissue associated with itching.

All comparative evidence is now gathered in our ​A-to-Z Supplement Reference.
