What Research Shows
There is not enough data to support that PC-SPES 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 take PC-SPES 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. Women who are pregnant or breastfeeding should not use PC-SPES.
