Hi @fisch, it's Lisa from the Policy Team. I just wanted to jump on to let you know that The Memorial Sloan Kettering Cancer Centre in New York have a very useful tool on their website called 'About Herbs' which you can use to search for particular herbs, botanicals and other products.
I have searched the 'About Herbs' and found
information about CanCell (also known as Protocel, like you said). According to the information provided by the website, Cancell has not been shown to treat or prevent cancer. There is a note that the National Cancer Institute tested CanCell on cancer cells in laboratory studies and found it does not have anticancer activity.
Here is a link to the 'About Herbs' tool in case you would like to look at further information about CanCell or other products:
https://www.mskcc.org/cancer-care/diagnosis-treatment/symptom-management/integrative-medicine/herbs.
As @primek said, we would always recommend you discuss any product with your oncologist before taking it because some products can interfere with cancer treatments.
Warm regards,
Lisa
