Primary Information, Benefits, Effects, and Important Facts

Scientific Information on Hemorrhoids


Human Effect Matrix

The Human Effect Matrix looks at human studies (it excludes animal and in vitro studies) to tell you what supplements affect hemorrhoids
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 Horse Chestnut Minor - See study
Preliminary evidence suggests that the classical usage of horse chestnut for the treatment of hemorrhoids may be relevant to oral supplementation, with benefits within a week of usage.
grade-c Cissus quadrangularis - - See study
Although some traditional usage of the herb suggests otherwise, limited (accessible) human data does not support a role for cissus in the treatment of hemhorroids

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

The evidence for each separate supplement is still freely available ​here.
