After taking Dong Quai (Angelica sinensis) for about 2 weeks my already low total testosterone decreased from 4.43 µg/L (443 ng/dL) to 3.33 µg/l (333 ng/dL).
It was 100 mg per day, it was part of the Now Foods Iron Complex, so I didn't put much attention to it, although I found sources that it's estrogenic.
