Misunderstanding of grape seed extract:

There are many experiments about grape seed extract inhibiting cancer cells on the Internet, but the conclusion will indicate this sentence: in vitro experiments can inhibit cancer cells. Li Duo, a professor in the Department of Food Science and Nutrition of Zhejiang University, explained that in vitro experiments can inhibit cancer cells and in vivo experiments can inhibit cancer cells, which is completely different.

After 12 months, breast induration and breast appearance were detected, and there was no difference between the two groups.
