New studies below.
A bit odd, today, reading of how the lychee fruit has regularly killed malnourished Indian children , & that the fruit inhibit epithelial-mesenchymal transition (EMT) in PCa .
I had a post last month on:
"Metformin & the Epithelial–Mesenchymal transition [EMT]"
The PCa study  is 'full text'.
I also discovered today that there are lychee extract products.
It's rare that I see fresh lychees for sale. Canned lychee can be found in Asian stores.
