“…Subsequent studies, however, did not confirm the ability of rooibos additions at dose 10 µg/mL to affect this marker of apoptosis. Furthermore, in these studies rooibos additions promoted accumulation of PCNA, which however did not alter cell viability (Sirotkin, Macejková, Tarko, Fabova, Alrezaki, et al, 2020; Sirotkin, Macejková, Tarko, Fabova, Alwasel, et al, 2020). Furthermore, in these studies rooibos was able to either promote (Sirotkin, Macejková, Tarko, Fabova, Alrezaki, et al, 2020) or reduce (Sirotkin, Macejková, Tarko, Fabova, Alwasel, et al, 2020) progesterone release.…”
