Herbal Supplement intake by pregnant or nursing women

The March of Dimes advises pregnant and nursing women to speak to their doctors before taking herbal supplements (March of Dimes 2002). Because of the following reasons, the March of Dimes states that it cannot be assumed that herbal supplements are safe:

1)  Some herbal supplements are suspected of causing harmful effects.

2)  Unlike drugs, supplements are not required by the Food and Drug administration to undergo rigorous testing to
     demonstrate their effectiveness and safety.

3)  Quality control standards to ensure a consistent amount of active ingredient and lack of contamination are not required for supplements.

4)  Some supplements can interact with medications and reduce their effectiveness.
