Saw palmetto may interact with anticoagulants; what is a common caution about its use?

• A. It may increase bleeding risk and is not recommended during pregnancy or breastfeeding; may affect hormone levels.
• B. It is not recommended during pregnancy or breastfeeding but has no hormonal effects.
• C. It has no potential interactions with anticoagulants.
• D. It should always be used with calcium supplements.

Answer: (A)

Saw palmetto can interact with anticoagulants because it may affect blood clotting by influencing platelet function, which can increase bleeding risk when used with anticoagulant medications. Because safety data for this herb in pregnancy and breastfeeding are limited and there are potential hormonal effects from its constituents, it is not recommended during pregnancy or breastfeeding and may affect hormone levels. This aligns with the best answer, which notes both the bleeding risk and the hormonal considerations, plus the caution in pregnancy and breastfeeding. The other statements imply no interactions or hormonal effects or add an unnecessary supplement, which does not fit what’s known about saw palmetto.
