It is likely safe to use red raspberry 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 not known whether it is safe to take by women who are breastfeeding. Large amounts of red raspberry during pregnancy should be avoided.1
Talk to your doctor about any supplements or therapy you would like to use. Some can interfere with treatment or make conditions worse.
