These leaves slow the growth of prostate tumors by 75%.

Sweet potatoes are known for their sweet, colorful flesh, but their leaves also offer a wealth of health benefits. They are popular in Asia and Africa and rich in vitamins, minerals, and especially powerful antioxidants called polyphenols, particularly    caffeoylquinic acid   .

Remarkable effects against some cancer cells

In the laboratory, extracts of sweet potato leaves have shown impressive activity against cancer cells.

In mice, a certain extract slowed the growth of prostate tumors by almost    75%   (2013 cacinochenesis study).

Other test-tube studies have shown that the agent is effective against breast, lung, colon and stomach cancer cells, and even against leukemia cells.

These results are promising, but it's important to remember that they come from preliminary research (in the laboratory or on animals) and not from clinical trials in humans.
