Ar-turmerone, a compound found in turmeric, increased stem cell growth in the rat brain by 80%.

“But there's also something in it called aromatic turmerone which is why specifically I like to get turmeric or make turmeric tea, not just curcumin. Because aromatic turmerone has been shown actually just in the past year to cross over the blood brain barrier and increase, I think it was in the subventricular zone, increased neural stem cell proliferation, and it affected like memory and performance in mice.”
