Rooibos tea is rich in a variety of polyphenols and is used for its anti-inflammatory and caffeine-free properties by women during pregnancy. However, a relationship between polyphenols and premature constriction of the ductus arteriosus (PCDA) has also been suggested. We experienced a case of PCDA in an infant whose mother began to drink Rooibos tea every day in the 26th week of pregnancy. The infant was a male with a birth weight of 3,099 g at gestational age of 36 weeks and 5 days. The infant was delivered by emergency Cesarean section due to placental dysfunction, and the Apgar score was 8/9. Respiratory distress was observed after birth and ductus arteriosus closure was confirmed by echocardiography; therefore, the infant was diagnosed with PCDA. His symptoms improved after oxygen supply and administration of furosemide and dobutamine, and he was discharged from hospital at age 26 days under home oxygen therapy. This case indicates the need to disseminate information on the possibility that PCDA may develop in newborn infants when their mothers drink Rooibos tea during pregnancy.
