“A lot of claims are being made, but most of them haven’t been tested scientifically,” Talcott said. “We are just beginning to understand the complexity of the acai berry and its health-promoting effects.”
In the current UF study, six different chemical extracts were made from acai berry pulp, and each extract was prepared in seven concentrations.
Four of the extracts were shown to kill significant numbers of leukemia cells when applied for 24 hours. Depending on the extract and concentration, anywhere from about 35 percent to 86 percent of the cells died.
