Introduction to Damiana Tea
Damiana (Turnera diffusa) is a wild shrub native to the Americas that has been used in traditional medicine for centuries, typically as an aphrodisiac, mood booster, and mild stimulant. Its leaves are most commonly brewed into a tea. Despite its historical use, modern scientific evidence is limited, and its safety profile is not fully understood, particularly in specific at-risk groups. It is crucial to understand the contraindications and precautions before consuming this herbal tea.
Key Groups Who Should Avoid Damiana Tea
Pregnant and Breastfeeding Individuals
Health authorities and experts strongly advise against the consumption of damiana tea during pregnancy and while breastfeeding. The primary reason for this is a lack of sufficient reliable information on its safety for both the mother and the infant. Animal studies have indicated that damiana may have an estrogen-lowering effect, which could potentially impact pregnancy. It is best to avoid damiana completely and consult a healthcare provider for any questions regarding herbal supplements during this period.
Individuals with Diabetes
One of the most significant contraindications for damiana tea is for people with diabetes. Damiana may decrease blood sugar levels, and when taken alongside antidiabetes medications like insulin, metformin, or glyburide, it could cause dangerously low blood sugar (hypoglycemia). This interaction can be severe and necessitates close monitoring and possible dosage adjustments by a doctor. Anyone managing diabetes should avoid damiana tea unless specifically advised and monitored by their healthcare provider.
People with Certain Mental Health Conditions
According to some health sources, individuals with specific mental health disorders, such as bipolar disorder or schizophrenia, should not consume damiana tea. Although the exact nature of the interaction is unclear, the herb's potential effects on the brain and nervous system could interfere with treatment or exacerbate symptoms. Consultation with a healthcare provider is essential for anyone with a psychiatric condition considering damiana.
Patients Undergoing Surgery
Because of its potential to affect blood sugar levels, damiana tea poses a risk during and after surgery. Unpredictable fluctuations in blood glucose can complicate surgical procedures. For this reason, medical professionals recommend discontinuing damiana use at least two weeks before any scheduled surgery.
Children and Infants
There is no reliable safety information regarding the use of damiana tea in children. Due to this lack of data and the potential for serious side effects, children should not be given damiana tea or any other damiana-based supplements. Pediatricians should always be consulted before giving any new herbal remedy to a child.
Individuals with Liver or Kidney Issues
While some animal studies suggest damiana may have protective effects on the liver and kidneys, other reports have indicated potential adverse effects or structural changes in these organs, especially with excessive doses. The overall safety for those with pre-existing liver or kidney conditions is not fully established. Extreme caution is advised, and individuals should monitor their liver function closely and discuss use with a healthcare provider.
Those with Iron Deficiency
Compounds within damiana, such as tannins and phenolics, may hinder the body's ability to absorb iron. Individuals with iron deficiency or anemia should use caution and consult their doctor before consuming damiana tea regularly to avoid worsening their condition.
Potential Side Effects and Overdose Risks
Even in otherwise healthy individuals, damiana can cause side effects, particularly when taken in high doses.
- Mild side effects: These include headaches, insomnia, and nausea.
- Serious side effects: Extremely high doses have been linked to hallucinations and convulsions.
- Allergic Reactions: Severe allergic reactions, such as hives, swelling, and difficulty breathing, are possible.

Conclusion: Prioritize Safety Before Consuming Damiana Tea
While damiana has a long history in herbalism, its potential risks and lack of comprehensive safety data mean it is not suitable for everyone. Pregnant and breastfeeding women, those with diabetes or specific mental health conditions, and individuals with liver or kidney disease should be particularly cautious or avoid it altogether. Furthermore, anyone on prescription medication, especially for diabetes, or preparing for surgery must consult a healthcare provider before use. Given the limited research, consulting a medical professional is the most responsible approach to ensure damiana tea is safe for your individual health circumstances.
