Māmaki, or Pipturus albidus, is a native Hawaiian plant that has been cherished for centuries in traditional healing, known as lāʻau lapaʻau. Unlike its stinging nettle relatives, māmaki is stingless and its leaves are typically brewed into a mild, earthy, and caffeine-free tea. The tea is celebrated for a variety of health benefits, including its rich antioxidant content, which supports cardiovascular health, digestion, and the immune system.
For most healthy adults, māmaki tea is generally considered safe and well-tolerated when consumed in moderation. However, like any herbal product, it is not without its potential side effects and precautions. Understanding these is key to enjoying māmaki responsibly and maximizing its nutritional benefits while minimizing any potential risks.
Potential Side Effects of Māmaki Tea
Mild Insomnia or Agitation
Despite being naturally caffeine-free, māmaki tea has some mild stimulating properties that can affect sensitive individuals. For some people, particularly those prone to insomnia, consuming māmaki tea late in the day may lead to mild agitation or difficulty sleeping. To avoid any sleep disturbances, it is best to enjoy this tea earlier in the day, especially if you are unsure how your body will react.
Diuretic Effects
Māmaki functions as a diuretic, meaning it can increase the frequency of urination. While this can be a gentle and supportive way to promote detoxification and kidney function, drinking large quantities can lead to frequent or troublesome urination. This effect is usually manageable with moderate intake but can be inconvenient if overdone.
Allergic Reactions
Allergic reactions to māmaki tea are rare but not impossible, especially for those with sensitivities to the Urticaceae (nettle) plant family. Symptoms of an allergic reaction might include mild itching or a skin rash. If you experience any of these signs, it is best to discontinue use immediately and consult a healthcare professional.
Laxative Effects from Berries
It is important to differentiate between the tea made from māmaki leaves and the berries of the plant. The gelatinous white berries that grow on the māmaki plant have a laxative effect and should not be consumed casually. Traditional Hawaiian practice involved using these berries specifically for their laxative properties, and they are not intended for regular dietary consumption.
Precautions and Contraindications
Pregnancy and Breastfeeding
There is a general lack of definitive scientific studies on the safety of māmaki for pregnant or nursing individuals. Some sources advise caution because plants in the nettle family can sometimes be galactagogues, which means they can increase milk production. While some sources claim it is safe, the prudent course of action is to consult a physician before consuming māmaki tea if you are pregnant or breastfeeding.
Drug Interactions
As with any herbal product, there is a possibility of drug interactions, especially if you are taking prescribed medications. While no significant interactions are widely documented for māmaki, it is always recommended to consult with your doctor or pharmacist before incorporating it into your routine, particularly if you have any pre-existing health conditions or are on a long-term medication regimen.
Proper Preparation and Consumption
To avoid potential issues and get the most out of your māmaki tea, follow these guidelines:
- Do not boil the leaves: Brewing the tea at a full boil can remove some of its healing properties. Instead, bring water to a boil, turn off the heat, add the dried leaves, and let them steep for about 15 minutes.
- Start with moderation: If you are new to māmaki, start with one cup a day to see how your body reacts before increasing your intake.
- Consume earlier in the day: To avoid potential sleep disturbances, drink your māmaki tea during the morning or early afternoon.
- Store properly: Once brewed, store any leftover tea in the refrigerator to prevent nutrient loss.
