Calendula officinalis, often called Pot Marigold, is an appreciated herb known for its bright flowers and gentle therapeutic properties. Its blossoms contain beneficial compounds, including flavonoids and carotenoids, used in both topical skin applications and internal consumption as a soothing tea. Utilizing this plant effectively involves understanding the correct preparation methods to extract its full benefits. This guide provides practical steps for transforming the calendula flower head into usable home remedies, from concentrated oil infusions to herbal teas.
Preparing Calendula for Use
Successful preparation begins with proper harvesting, ideally plucking the fully opened flower heads on a dry, mid-morning when the dew has evaporated. The entire flower head, including the sticky green base, should be dried, as this part holds many of the plant’s beneficial components. To prevent mold, spread the blossoms in a single layer on a screen or dehydrator set between 80°F and 100°F until the centers are completely crisp and crumble easily.
Once thoroughly dried, the flowers are ready for infusion into oil or water. For oil infusion, the base for most topical preparations, loosely fill a clean glass jar about halfway with the dried flowers. Cover them completely with a carrier oil like olive or jojoba oil. Allow the mixture to infuse for four to six weeks in a warm, dark place, shaking it daily, or use a low-heat method like a slow cooker or double boiler for several hours.
To create a water infusion, place one to two teaspoons of dried calendula flowers per cup of water into a mug or teapot. Pour hot water, just below boiling point (around 95°C), over the flowers and allow it to steep for 10 to 15 minutes. For a more potent infusion suitable for external washes, use a higher ratio of up to one-third cup of dried flowers per cup of water and let it steep overnight. Strain the plant material from the liquid before use.
Topical Application Methods
The calendula-infused oil is the base for creating a soothing skin salve. A common ratio for a firm balm is combining one cup of infused oil with one ounce of beeswax or a vegan wax alternative. Gently melt the wax and the oil together in a double boiler, ensuring the mixture does not overheat. Then, pour the liquid into small, clean tins or jars to cool and solidify.
This finished salve is a remedy for minor skin irritations, chapped lips, dry patches, and cracked skin due to its antifungal and anti-inflammatory properties. The infused oil can also be used directly as a moisturizing treatment for the body or face, helping to soothe conditions like mild eczema or diaper rash. Avoid applying oil-based products to open, weepy, or infected wounds, as the oil can trap heat and moisture.
In cases of acute inflammation or weepy skin conditions, the water-based infusion should be used as a compress or wash instead of the oil. Saturate a clean cloth or gauze in the cooled, strong calendula tea and apply it directly to the affected area. This water-based application is useful for rashes, minor scrapes, or as a gentle wash for post-operative sites, as it delivers the plant’s soothing compounds without sealing the skin.
Internal Consumption Guidance
Calendula is safe for ingestion and is most commonly consumed as a mild, slightly peppery herbal tea. To brew a pleasant cup, steep one to two teaspoons of dried petals in hot water for five to ten minutes, adjusting the time for personal preference. The flavor profile is generally mild and floral with earthy undertones, though a slight bitterness can be balanced with honey or lemon.
Drinking calendula tea is traditionally used to address internal inflammation, support the lymphatic system, and ease digestive discomfort. The tea is naturally caffeine-free and may be consumed daily. For a more concentrated internal use, a calendula tincture can be prepared by soaking the dried flowers in a high-proof alcohol for several weeks.
Tinctures are taken in small doses, typically 10 to 25 drops diluted in water, up to four times per day, but professional guidance is helpful for exact dosing. Beyond medicinal applications, the fresh petals can be used as a vibrant, edible garnish on salads or desserts. The bright yellow-orange color of the petals also makes them a natural food dye, serving as an inexpensive substitute for saffron in rice dishes or butter.
Sourcing and Safety Considerations
When acquiring calendula, ensure you are using Calendula officinalis, as other common marigolds (Tagetes species) are not typically used for consumption or herbal remedies. Seek out organically grown flowers to minimize pesticide exposure, especially when preparing teas or culinary dishes. The quality of the dried flower is judged by its vibrant color and pleasant aroma, indicating the retention of beneficial compounds.
A safety consideration is the plant’s membership in the Asteraceae family, which includes common allergens like ragweed, daisies, and chrysanthemums. Individuals with known allergies to these plants should exercise caution, as they may experience an allergic reaction. Calendula should be avoided internally during pregnancy due to its traditional use as a uterine stimulant.
It is also advisable to stop using calendula at least two weeks before any scheduled surgery, as it may interact with sedative medications and increase drowsiness. Finished products, whether dried flowers, infused oils, or salves, should be stored in airtight glass containers in a cool, dark location. Proper storage helps maintain the herb’s potency for up to a year and prevents rancidity or molding.
