Kava Root Safety During Pregnancy: What's The Verdict?

Kava, a medicinal herb native to the Pacific Islands, is known for its sedative and anesthetic properties. It is often consumed to treat anxiety and insomnia, and its popularity is growing in the United States, especially in kava bars. However, the question of whether it is safe for women to consume during pregnancy is a complex one. While some women, particularly in Vanuatu, advocate for its use as a natural pain reliever during pregnancy, there are concerns about its potential side effects and lack of research. The American Pregnancy Association and the U.S. Food and Drug Administration (FDA) have deemed kava as possibly unsafe for pregnant women due to the risk of liver injury and potential harm to the fetus. Existing research suggests links between kava consumption and hepatotoxicity or liver damage, which is a serious concern during pregnancy as hormonal changes make women more susceptible to liver toxicity. Additionally, the varying strength and quality of kava products make it challenging for pregnant women to monitor their dosage accurately. As a result, most practitioners recommend against the routine use of kava during pregnancy, opting for a zero-tolerance approach to any substances. While further research is needed to conclusively determine the safety of kava during pregnancy, it is generally recommended that pregnant women avoid its consumption and consult their healthcare provider before taking any herbal supplements.

Kava may cause liver damage to the foetus

Kava is deemed “possibly unsafe” and should be avoided in all forms, including tea, roots, and powder. The American Pregnancy Association has given kava this classification due to the risk of liver injury, including hepatitis, cirrhosis, and liver failure. The U.S. Food and Drug Administration (FDA) does not recognise kava as a substance that is "Generally Recognized As Safe" (GRAS) for this reason.

Kava has been linked with liver injury that can lead to death. This is especially concerning for pregnant women due to the pyrone content. The physical and hormonal changes that occur during pregnancy make women more susceptible to liver toxicity. The strength of kava is not consistent, and natural and herbal products are not subject to the same rigorous safety testing, research, or standards for manufacturing as prescription medications. This makes it very difficult for women to monitor the dose of kava their unborn child is exposed to.

Additionally, kava may weaken the muscles in the uterus, leading to pregnancy complications. It can also prolong the effects of anaesthesia, which could be problematic if a mother requires sedation for a cesarean section or other surgery.

Until clinical trials have confirmed that kava's benefits outweigh its risks for expectant mothers, most practitioners recommend against its use during pregnancy.

Kava may cause fetal distress during labour

Kava is a medicinal herb native to the South Pacific islands, which has gained popularity as a tea in the United States. It is known for its ability to calm the central nervous system and relax the muscles, making it a popular remedy for anxiety and insomnia. However, despite its therapeutic benefits, kava consumption during pregnancy is generally not recommended due to safety concerns.

One of the primary concerns regarding kava use during pregnancy is the potential risk of fetal distress during labour. Kava may cause uterine weakness or decreased muscle tone in the uterus, which can lead to complications during pregnancy and labour. This effect on the uterus could result in difficulties during childbirth and potentially cause fetal distress.

In addition, kava can prolong the effects of anaesthesia. This could be problematic if a mother requires sedation for a caesarean section or another surgical procedure during labour. The prolonged anaesthetic effects could impact the well-being of both the mother and the fetus, leading to further complications.

Moreover, kava contains compounds that can pass into breast milk and potentially harm a newborn. The pyrone content in kava, for instance, has been flagged as a possible concern for pregnant and breastfeeding women. While the exact nature of this risk is not specified, it underscores the necessity for caution when considering kava consumption during pregnancy and breastfeeding.

The potential risks of kava consumption during pregnancy are serious enough that the American Pregnancy Association has deemed it "Possibly Unsafe". This classification is given to substances that have not been confirmed as safe or unsafe for pregnant women due to insufficient evidence. The lack of conclusive research on kava's effects during pregnancy underscores the need for caution and highlights the importance of consulting a physician before consuming kava while pregnant.

In conclusion, while kava may offer therapeutic benefits for anxiety and insomnia, its consumption during pregnancy is generally discouraged due to safety concerns. The potential risk of fetal distress, prolonged anaesthetic effects, and the presence of compounds in breast milk all contribute to the classification of kava as "Possibly Unsafe" for pregnant women. Until further research clarifies kava's effects during pregnancy, it is recommended that pregnant women opt for other anxiety relief methods and maintain a zero-tolerance approach to any substances during pregnancy and labour.

Kava may cause overproduction of milk, leading to mastitis

Kava is a beverage derived from the roots of the Piper methysticum plant, which is native to the Pacific Islands. It is known for its sedative and anesthetic properties, calming the central nervous system and relaxing the muscles. While kava is often used to treat anxiety and insomnia, its consumption during pregnancy is deemed unsafe.

John Fordham, the owner of Kava Klin, cautions against the use of kava during pregnancy, specifically because it may cause overproduction of milk, leading to mastitis. This concern is echoed by Kristina James, a midwife based in Queensland, who believes that the potential harm extends beyond mastitis and could negatively affect the developing fetus.

The American Pregnancy Association and the U.S. Food and Drug Administration (FDA) have deemed kava as "Possibly Unsafe" for pregnant women. This is due to the risk of liver injury and the presence of chemicals that may pass into breast milk, potentially harming the infant. Therefore, it is recommended that pregnant and breastfeeding women avoid consuming kava in any form, including tea, roots, and powder.

While some women in Vanuatu, the country where kava is exported from, believe that drinking kava can help relieve pregnancy pain, especially during the last two months, healthcare professionals generally advise against it. The varying strength of kava makes it challenging for pregnant women to monitor the dose their unborn child is exposed to, and there is limited research on the specific effects of kava on pregnant women and their developing fetuses.

As a result, the general recommendation from medical professionals is for pregnant and lactating women to refrain from consuming kava and opt for a zero-tolerance approach to any substances.

Kava may weaken the muscles in the uterus, leading to complications

Kava is a medicinal herb native to the South Pacific islands, which has gained popularity as a tea in the United States, especially in kava bars. It is known for its sedative and anesthetic properties, calming the central nervous system and relaxing the muscles. However, despite its potential benefits in reducing anxiety, kava is deemed unsafe for consumption during pregnancy.

The American Pregnancy Association and the U.S. Food and Drug Administration (FDA) have both cautioned against consuming kava during pregnancy, classifying it as "Possibly Unsafe". This classification is due to the potential risk of liver injury, including hepatitis, cirrhosis, and liver failure, which can be life-threatening for both the mother and fetus. Additionally, kava may be especially unsafe for pregnant and breastfeeding women due to its pyrone content.

Furthermore, kava may weaken the muscles in the uterus, leading to potential complications during pregnancy. This effect on the uterus could result in fetal distress and further implications for both the mother and child. The exact mechanism by which kava influences uterine muscle function is not yet fully understood, but the potential risk is concerning.

The potential risks of kava consumption during pregnancy are serious enough that even kava exporters in Kiribati include a disclaimer with their products, reminding pregnant women not to consume kava. This is because the potential harm to the developing fetus could have long-lasting consequences. While kava may seem appealing as a natural and holistic remedy for anxiety and stress during pregnancy, the lack of scientific evidence and potential risks currently outweigh the benefits.

Kava may prolong the effects of anaesthesia

Kava is a substance derived from the roots of a plant that has sedative and anesthetic properties. It is known to calm the central nervous system and relax the muscles. It is often consumed as a tea, root, or powder.

While kava is known to have relaxing qualities and is used to treat anxiety and insomnia, it is not safe for everyone. Kava is deemed "possibly unsafe" for pregnant and breastfeeding women and may cause liver damage. The U.S. Food and Drug Administration (FDA) does not recognize kava as a substance that is "Generally Recognized As Safe" due to the risk of liver injury, including hepatitis, cirrhosis, and liver failure.

Additionally, kava may prolong the effects of anaesthesia. It is recommended that patients discontinue the use of kava 24 hours before surgery as it may reduce anaesthetic requirements. This is because kava has sedative and anxiolytic properties, which can enhance the effects of anaesthetic agents. Kava may act through the inhibition of sodium and calcium channels, leading to decreases in systemic vascular resistance and blood pressure. It can also cause adverse neurological effects due to its benzodiazepine and antidepressant activities, which may result in excessive perioperative sedation.

Furthermore, patients often do not disclose their use of herbal substances, and drug interactions can occur without being suspected as the cause of changes in patient homeostasis. Therefore, it is essential to provide patient education about the potential adverse consequences of kava use, especially in the perioperative period.
