Calendula tea, derived from the vibrant yellow calendula flower, has a long history of traditional use, but modern science is only beginning to explore its potential health benefits. While not a mainstream beverage like chamomile or green tea, this naturally caffeine-free infusion offers a unique set of properties that may support wellness. Here’s a breakdown of what you need to know.
What is Calendula Tea?
Calendula (Calendula officinalis ) is a flowering plant with roots in folk medicine. The flowers, sometimes called pot marigolds, have been used for centuries for their purported healing abilities. The tea itself is brewed from the dried flowers and leaves, resulting in a slightly bitter, earthy-flavored yellow beverage. It’s not typically found in standard grocery stores, often requiring purchase from specialty tea providers or online retailers where it costs roughly $1 to $3 per ounce.
Despite lacking significant macronutrients, calendula tea contains antioxidants like terpenes, flavonoids, polyphenols, and carotenoids. These compounds are believed to reduce inflammation in the body, though more research is needed to confirm these effects.
Potential Health Benefits
While much of calendula’s historical use remains unverified by robust modern studies, several areas show promise:
- Fever Reduction: Traditionally used to lower fevers, calendula’s astringent and anti-inflammatory properties may contribute to this effect. However, current scientific evidence is limited, and further investigation is crucial.
- Skin Health: Calendula creams are well-known for wound healing and hydration. While tea offers antiseptic properties, topical applications (creams, lotions) are more effective for skin issues like firmness, inflammation, and tissue regeneration.
- Potential Anti-Cancer Effects: Preliminary research suggests calendula may activate proteins that kill cancer cells. One study even found it outperformed chamomile in antitumor potential. However, this is preclinical research, and definitive conclusions cannot yet be drawn. Topical calendula extracts have shown promise in preventing radiation-induced dermatitis in breast cancer patients, but this was achieved through direct application, not by drinking the tea.
- Menstrual Relief: Calendula tea has been traditionally used to ease menstrual cramps, although more research is needed to confirm these effects. Some studies suggest it may even stimulate menstruation in cases of absence, but consultation with a doctor is essential.
- HIV Inhibition (Limited Evidence): An older study suggests calendula extract may inhibit HIV-1 replication. However, this research is outdated and requires replication with modern methodologies.
How to Incorporate Calendula Tea
Due to limited scientific backing, a precise dosage for optimal effects remains unclear. However, daily consumption is generally considered safe, and it can be a healthy alternative to sugary beverages.
Herbalist Rachelle Robinett recommends brewing calendula in larger batches and refrigerating for later use. It can also be added to smoothies, oatmeal, or other recipes as a unique flavor addition. There is no specific best time to drink it; enjoy it as a soothing evening beverage or a warm morning alternative to coffee.
Brewing Instructions
For maximum extraction of beneficial compounds, consider a decoction method:
- Heat 8 ounces of water with 2 teaspoons of calendula flowers over low heat.
- Simmer gently for 10–15 minutes.
- Remove from heat and steep for an additional hour.
- Strain and enjoy.
Safety and Side Effects
Calendula is generally considered safe, but allergic reactions are possible, especially for individuals sensitive to marigolds or plants in the Asteraceae family. It may also interact with certain medications, including sedatives, blood pressure drugs, and diabetes treatments. Consult with a healthcare professional if you have concerns. Pregnant women should avoid calendula due to potential interference with conception or labor.
The Bottom Line
Calendula tea has a rich history in traditional medicine, and emerging research suggests potential benefits for fever reduction, skin health, and even cancer palliative care. However, much of the evidence is preliminary, and more studies are needed to confirm these effects. While not a miracle cure, it remains a safe and potentially healthful beverage that could be worth exploring as part of a broader wellness routine.
