Lemongrass (Cymbopogon citratus) is a fragrant plant widely used globally as a culinary spice and in herbal preparations. Its distinct, citrusy aroma makes it a popular flavoring agent in teas, soups, and curries, particularly in Southeast Asian cuisine. Expectant mothers often question the safety of consuming herbs during pregnancy. This article addresses the use of lemongrass in its various forms during gestation.
Understanding Consumption Levels
The safety of lemongrass consumption depends heavily on the concentration and amount ingested. Using fresh or dried lemongrass in small quantities purely for flavoring meals, such as in a stir-fry or curry, is considered low-dose exposure. The minimal amount of active compounds in a typical serving is unlikely to pose a health risk.
Conversely, ingesting lemongrass in high concentrations requires caution, as the dosage of active compounds increases dramatically. High-dose exposure typically occurs when consuming strong herbal teas, tinctures, or concentrated supplements. Safety concerns during pregnancy center almost exclusively on these medicinal or highly concentrated forms.
Specific Safety Concerns During Pregnancy
The main concern with consuming high doses of lemongrass relates to its traditional classification as an emmenagogue. An emmenagogue is a substance historically used to stimulate blood flow in the pelvic area and uterus. This action raises the possibility of uterine stimulation or contractions, potentially increasing the risk of adverse outcomes, especially early in pregnancy.
Lemongrass contains chemical compounds, notably citral and myrcene, responsible for its flavor and biological activity. High intakes of these concentrated compounds, such as in strong teas or supplements, trigger medical warnings.
Some research suggests that very high levels of myrcene could affect fetal skeletal development, though this is based on concentrated animal studies. Lemongrass may also affect blood pressure and blood sugar levels. Pregnant individuals managing gestational diabetes or hypertension should be aware that consuming therapeutic amounts could interfere with existing medical management.
Topical and Aromatherapy Use
Lemongrass essential oil presents different considerations than ingesting the whole herb. Essential oils are potent, highly concentrated forms of the plant’s compounds extracted through distillation. Topical application involves the oil being absorbed through the skin and into the bloodstream, allowing compounds to circulate systemically.
Due to its high concentration of citral, the essential oil can act as a skin sensitizer, potentially causing irritation or allergic reactions even when diluted. For aromatherapy, compounds enter the body via the respiratory system through inhalation.
While inhalation is considered less risky than ingestion, essential oils should be used sparingly and only in well-ventilated areas during pregnancy. The consensus is to avoid essential oils entirely or use them with extreme dilution and professional guidance due to limited safety data.
Seeking Professional Medical Guidance
Clinical trials on the safety of herbal products are rarely conducted on pregnant populations, meaning conclusive evidence on lemongrass is limited. The most prudent course of action is to consult with a healthcare provider, such as an obstetrician or midwife, before using any herbal product. This discussion should cover all forms of consumption, including teas, supplements, and essential oils.
A healthcare professional can assess the risk based on the individual’s specific health history and pregnancy status. The quality and purity of herbal products are also a major consideration.
Contaminants or inconsistent potency in unregulated products can introduce additional, unknown risks. Unless specifically approved by a physician, expectant mothers should limit consumption to small culinary amounts and avoid therapeutic doses entirely.
