We summarize the clinical evidence for each medical benefit here. We begin with our assessment of the strength of evidence within each category, followed by a brief summary of individual studies or reviews of several studies. In assessing the strength of evidence, we consider the study design, number of participants, and the size of the treatment effect (how much outcomes changed with treatment).
To see more details, click the plus sign to the right of any section.
Our assessments of evidence for each medical benefit fall into one of these categories:
- Strong evidence: consistent, significant effects in several large (or at least one very large) well designed clinical studies or at least two meta-analysesa statistical analysis that combines the results of two or more research studies; the results of smaller research studies addressing the same or similar questions can be analyzed as though they are one bigger, more powerful study of clinical studies of moderate or better quality (or one large meta-analysis) finding similar results
- Good evidence: significant effects in one large or several mid-sized and well-designed clinical studies ( randomized controlled trialsa study design in which people are randomly assigned to either an experimental group or a control group to compare the outcomes from different treatments; an RCT is considered a strong design for determining a therapy’s effects with an appropriate placebo or other strong comparison control or observational studies that control for confounds)
- Modest evidence: significant effects in at least three small but well-designed randomized controlled trials (RCTs), or one or more well-designed, mid-sized clinical studies of reasonably good quality (RCTs or observationala type of study in which individuals are observed or certain outcomes are measured, but no attempt is made to affect the outcome (for example, no treatment is given); an example is a study that records people’s diets, but doesn’t try to alter their diets, and looks for patterns of disease or other outcomes related to different foods studies), or several small studies aggregated into a meta-analysis
- Preliminary evidence: significant effects in small or poorly designed clinical studies OR conflicting results in adequate studies but a preponderance of evidence of an effect
- Weak evidence: one or more case studies, supported by animal evidence OR small treatment effects of limited clinical significance OR studies with no controls OR weak trends of effects
- Insufficient evidence: preclinical evidence only OR clinical studies with such poor or unclear methodology that no conclusion can be drawn OR conflicting findings across clinical studies with no preponderance of evidence in one direction; conflicting evidence occurs when studies find conflicting effects (positive effect vs no effect or negative effect) with the same treatment and the same general study population (same cancer type, for example)

Improving treatment outcomes
Is berberine linked to improved survival? Is it linked to less cancer growth or metastasis? Does it enhance the anticancer action of other treatments or therapies?
The only published evidence we have found regarding berberine’s use in improving treatment outcomes is preclinical—involving cells, tissues, or lab animals. Preclinical evidence is a first step toward finding whether a therapy has anticancer activity. Without any evidence of effects in living humans, we do not recommend concluding that berberine might have anticancer effects for you. The preclinical evidence is promising, but we consider it still only a weak indication of possible effects in people with cancer. Preclinical evidence is a bit like taking a poll several months before an election. Most of us would not be comfortable saying that the election results will be identical to the poll, and sometimes the election results are not at all what the poll predicted.
Preclinical evidence for improving treatment outcomes
All the evidence of berberine’s effects on treatment outcomes so far is preclinical. The strongest evidence to date shows improved survival in animals treated with berberine, which has been reported only in lung cancer and multiple myeloma.
