I read an interesting study from a mainstream medical source showing it help slow oral cancer, was being tested on patients leading up to surgery for that.
It’s very difficult to get sufficient dosage into the bloodstream for therapeutic benefit. Transdermal patches have ben tried, very messy, pronounced yellowing. Sublingual liquid might be helpful being that it was oral cancer. State of the art appears to be liposomal curcuminoids but not certain if even that surmounts the problem of bioavailability.
