Pei Pa Koa, a seemingly ordinary and easily reachable traditional cough medicine, can be harmful especially to pregnant women and young children because Pei Pa Koa contains licorice (甘草).

This ingredient will cause several effects:

1. Hormonal Effects: Licorice contains glycyrrhizin, which can mimic the hormone aldosterone. High levels of aldosterone can lead to fluid retention, hypertension, and an imbalance of electrolytes in the body.
2. Blood Pressure Issues: Glycyrrhizin can cause an increase in blood pressure by reducing potassium levels and increasing sodium levels in the body. High blood pressure during pregnancy can lead to complications such as preeclampsia.
3. Preterm Labor Risk: Some studies suggest that consuming large amounts of licorice during pregnancy may increase the risk of preterm labor due to its effects on prostaglandin synthesis.
4. Developmental Issues: There is evidence suggesting that excessive licorice consumption during pregnancy might affect the cognitive development of the child. It has been associated with lower intelligence and behavioral problems in children.

This situation underscores the importance of consulting your healthcare professional before taking any medication, including herbal medicines, during pregnancy. Always seek professional advice to ensure the health and safety of both the mother and the baby.
