Why is oral consumption of yarrow strongly advised against during pregnancy?

Answer

It possesses emmenagogue properties that risk causing uterine contractions.

The most severe contraindication regarding yarrow use centers specifically on reproductive health, rendering its internal consumption unsafe during gestation. Yarrow contains specific active components that exhibit documented emmenagogue properties. An emmenagogue is a substance capable of stimulating or increasing menstrual flow. When introduced into a pregnant system, this stimulation translates directly into a risk of inducing uterine contractions. If these contractions occur forcefully or are sustained, they carry the potentially catastrophic risk of causing a miscarriage. Due to this clearly established danger, medical professionals strongly caution against any form of oral intake of yarrow, including teas, during pregnancy. Furthermore, the volatile oil component, in particular, should be rigorously avoided throughout the entire pregnancy period.
