Yes, and it’s still working, why is this upsetting rather than exciting to you? Maca is no common herb, the mechanism of action is still unknown. It boosts libido in women and men without affecting serum steroid levels and a lot of people might have missed it by using a dose which was too low.
And another common herb is Saw Palmetto a natural 5α-Reductase inhibitor which can cause the same side effects as finasteride. If a common herb can cause these symptoms I don’t see why a common herb could help against them. Whether something is common or not is completely insignificant.
