However, a Cochrane systematic review encompassing five randomized controlled trials (415 women) found insufficient very low-quality evidence to support its effectiveness in improving clinical pregnancy rate (RR 1.38, 95% CI 0.91 to 2.10), live birth rate, overall pain, miscarriage rate (Peto OR 1.99, 95% CI 0.20 to 19.37), or endometriosis recurrence (RR 0.84, 95% CI 0.30 to 2.36), highlighting the need for higher-quality trials (65)

Different research found that while the full Scutellaria baicalensis extract failed to demonstrate any particularly inhibitory effects on MCF-7 cells, it did imply that a fraction of the SbE exhibited chemopreventive properties (94)

Biological activity is also altered

Recently identified derivatives of bile acids (called tertiary bile acids), have shown the ability to act simultaneously on GPBAR and also on RORt on which some of them exert an inverse agonist activity
