What Research Shows
Not Enough Data to Assess
There is not enough data to support that cleavers is helpful in treating health problems. We will review future studies as they are published.
Editorial process and description of evidence categories can be found at EBSCO NAT Editorial Process.
It may be safe to use cleavers on the skin and to take it orally in small doses for a short time. Not enough studies have been done to say whether it is safe to use for a long period. It is also not known whether it is safe to take by women who are pregnant or breastfeeding.
Talk to your doctor about any supplements or therapy you would like to use. Some can interfere with treatment or make conditions worse.
