Is Mugwort Tea Safe During Pregnancy?

Mugwort tea, an herbal infusion derived from the Artemisia vulgaris plant, is generally considered unsafe for consumption throughout pregnancy. This caution is based on potential risks to the developing fetus and the pregnant individual. Health organizations and herbalists strongly advise against drinking this tea due to its pharmacological effects. Mugwort should be avoided entirely during all trimesters of pregnancy due to the potential for serious complications.

Understanding Mugwort and Its Traditional Uses

Mugwort (Artemisia vulgaris) is a perennial plant with a long history of use across many cultures. Its leaves and flowering tops are dried and steeped to create a bitter, aromatic herbal tea. Historically, mugwort has been valued as a digestive aid, used to stimulate appetite and soothe stomach upset, including bloating and flatulence.

It was also traditionally used as a nerve tonic and to promote vivid dreams. In European traditions, it was commonly used as a flavoring agent in gruit ales before hops became standard for brewing.

The Primary Safety Concern: Emmenagogue Properties

The primary reason medical professionals advise against mugwort tea during pregnancy is its classification as an emmenagogue. Emmenagogues are substances that stimulate blood flow in the pelvic area and uterus, which can trigger menstruation or uterine contractions. This stimulatory effect on the uterus is what poses a direct risk to a pregnancy.

The volatile oils within mugwort contain compounds, specifically thujone, that are responsible for this uterine stimulation. Thujone is a potent neurotoxin that can cause convulsions and is toxic in large doses. The uterine-stimulating action increases the risk of miscarriage in early pregnancy or the possibility of preterm labor later on.

The concentration of these volatile oils can vary significantly based on the plant’s growing conditions, harvest time, and preparation method. Because of this inconsistency, there is no reliably safe dosage of mugwort tea for a pregnant individual. Therefore, even a small amount of the tea is discouraged due to the unpredictable nature of its active compounds.

Official Medical Consensus and Safer Alternatives

The consensus among obstetricians, midwives, and major health organizations is to abstain from consuming mugwort tea during pregnancy. Due to the lack of extensive human studies, the herb is designated as likely unsafe when taken orally by pregnant individuals. This caution extends throughout all nine months to avoid potential uterine irritation or negative fetal effects.

Any pregnant individual considering herbal supplements or teas should first consult with a healthcare provider. For those seeking warm beverages or support for common pregnancy discomforts, several well-studied alternatives exist.

Safer Alternatives

Ginger tea is widely considered safe in moderation and is often recommended for soothing morning sickness. Peppermint tea is another option that can help ease flatulence and an upset stomach when consumed in limited amounts.
