Which herb is contraindicated during pregnancy due to its diuretic properties?

• A. Long Dan Cao
• B. Da Huang
• C. Qu Mai
• D. Mu Tong

Answer: (C)

The main idea is that herbs with strong diuretic effects are avoided in pregnancy because increased urine flow can lead to dehydration and may stimulate uterine contractions, risking miscarriage or premature labor. Qu Mai is known for its rapid, notable diuretic action to promote urination. Because of this strong diuretic effect, it can irritate the uterus and increase the likelihood of pregnancy loss, so it is contraindicated during pregnancy. The other herbs listed do not have diuretic action as their primary effect, so they don’t carry the same pregnancy-specific risk in this context.
