Marigold has much value today and in traditional cultures as a homeopathic remedy, but the oil extracted from the flowers, called calendula oil, is not far behind in providing benefits.
Learn more about this oil distilled from the petals of the pot marigold or Calendula officinalis, and how you can harness its health and practical everyday uses.
What Is Calendula Oil?
Marigold is a genus of about 15 to 20 species of plants in the Asteraceae family.1 This flower is native to Southwestern Asia, as well as Western Europe and the Mediterranean.
The common name “marigold” refers to the Virgin Mary, with whom it has been associated since the 14th century, when it was included as an ingredient in an English recipe for fighting plague.2
Apart from also being used to honor Mary during Catholic events, marigold was also considered by ancient Egyptians to have rejuvenating properties.3 Hindus used the flowers to adorn statues of gods in their temples, as well as to color their food, fabrics and cosmetics.
Pot marigold or C. officinalis is the most commonly cultivated and used species, and is the source of the herbal oil. “Calendula” comes from the Latin word “calendae,” meaning “little calendar,” because the flower blooms on the calends or the first of most months.4
It should not be confused with ornamental marigolds of the Tagets genus, commonly grown in vegetable gardens.5
Calendula, with fiery red and yellow petals, is full of flavonoids, which are found naturally in vegetables and fruits and are substances that give plants their lovely bright colors.6
Calendula oil is distilled from the flower tops and is quite sticky and viscous. It has a very strange smell described as musky, woody and even rotten — like the marigold flowers themselves. This smell does not readily appeal to many individuals, even when used in a remedy.
Uses of Calendula Oil
Here are three classifications of calendula plant and oil uses:
1. Health and wellness — It has tonic, sudorific, emmenagogic and antispasmodic properties, but it is mainly used for skin care and treatment.7
It has great anti-inflammatory and vulnerary action, making it helpful with stubborn wounds, acne, ulcers, bed sores, varicose veins, rashes, eczema and related conditions.8 It helps soothe sore, inflamed and itchy skin conditions.
Calendula massage oil also assists in soothing, and softening skin, making it a good addition to massage oils or when preparing a carrier oil blend.
2. Cooking — Since the Middle Ages, the petals of marigold have been used as “the poor man’s saffron” for coloring cheeses, butters and side dishes.
During the Elizabethan era, both petals and leaves were used in salads, although the latter showed to be very strong. The petals flavored soups and stews.
3. Practical uses — Marigold has been used as a dye. Dried petals can also be added in potpourris.
Composition of Calendula Oil
In a study,9 calendula oil was obtained in low yield (0.3 percent) by steam distillation with cohobation from flowers and whole plants. Identified by the researchers were 66 components, mainly sesquiterpene alcohols with α-cadinol as the main constituent, at about 25 percent.
The essential oil from the whole plant was differentiated from that of the flowers through the presence of monoterpenes hydrocarbons, aside from the alcohols.
The principal constitutes of calendula essential oil10 are flavonoids, saponosene, triterpenic alcohol and a bitter principle. The useful components of calendula itself include a volatile oil, carotenoids, flavonoids, mucilage, resin, polysaccharides, aromatic plant acids, saponins, glycosides and sterols.11
Benefits of Calendula Oil
Calendula oil is traditionally used for abdominal cramps and constipation.12 It’s your skin that will receive a good bulk of the benefits, though, thanks to the oil’s anti-inflammatory, antibacterial and related properties. Here are some of the promoted benefits of this oil:13
1. Skin dryness or chapping — Calendula oil is a great moisturizer for dry skin and for severely chapped or split skin. It helps soothe the area and reduce the pain.
2. Inflammation — It works well on sprained muscles or bruises; its anti-inflammatory action helps lessen swelling from injury. Calendula oil also helps treat spider veins, varicose veins, leg ulcers and chilblains.
3. Baby care — The oil helps relieve diaper rashes, which can extremely irritate an infant.
4. Minor cuts and wounds — The antiseptic and antimicrobial action of the oil help speed up healing of wounds and minor cuts, and also help relieve insect bites, acne and bed sores.
5. Skin issues — Eczema, psoriasis, dermatitis and other skin problems can be soothed using calendula oil, applied topically. Calendula oil’s antifungal action is also great for helping treat athlete’s foot, ringworm and jock itch.
How to Make Calendula Oil
Calendula oil is extracted by steam distillation.14 There is almost no way to obtain 100 percent pure calendula essential oil, so this makes calendula essential oil an infusion and not a pure extract.15
In order to get the oil from the flower, the petals are steeped in oil, preferably olive oil. The oil left over when distillation is done is calendula oil, which should be a golden orange color.
You can create homemade calendula oil using the following instructions from Keeper of the Home.16
What you will need:
• Dried calendula petals
• Carrier oil (olive oil, almond oil or sunflower oil are some great options)
• A clean glass jar with a lid
• Cold infusion method — This is the usually preferred technique because it protects the delicate calendula from heat damage.
1. Put your desired amount of dried calendula petals in a clean, dry glass jar.
2. Fill the jar with your carrier oil of choice to cover the petals by an inch.
3. Put in a sunny place to infuse for four weeks.
4. Drain the petals from the oil and store the oil in a container with a lid for up to one year.
• Hot infusion method — This method is much quicker than the cold infusion method but won’t have the same strength because of the presence of heat.
1. Put your desired amount of dried calendula petals in a clean, dry glass jar.
2. Fill the jar with your carrier oil of choice to cover the petals by an inch.
3. Dump the entire contents of the jar (the petals and the oil) in a small saucepan or slow cookers. Heat on low for four hours, stirring occasionally.
4. Let cool. Drain the petals from the oil and store the oil in a container with a lid for up to one year.
You can use the homemade calendula oil as an after-bath body oil, salve,17 baby oil, lotion18 or home remedy for dry skin, inflamed areas, or rashes.
How Does Calendula Oil Work?
Calendula oil is used in various products, oftentimes as a great base for lotions, salves, creams, several natural cosmetics and personal care products and herbal ointments. It also very commonly works as a base oil in aromatherapy. Furthermore, you can use calendula oil in an all-natural herbal hair color recipe.19
You can create an infused oil by filling a jar with the dried flowers, which you cover with a carrier oil.20 You can get more out of these flowers by macerating the mixture in a blender. Leave it infused for two weeks or more to extract the flowers’ beneficial properties. When ready to use, filter the oil through cheesecloth, and use it directly in a balm or as part of a homemade cream or lotion.
Is Calendula Oil Safe?
Calendula oil is generally safe for use, but I advise you to heed the following safety guidelines and considerations:21
1. Pregnant and breastfeeding women should generally avoid using calendula oil. Do not take calendula by mouth, as there is a concern that it might cause a miscarriage. Avoid topical use as well.
2. An allergic reaction may occur in individuals who have sensitivity to ragweed and related plants, such as marigolds, chrysanthemums and daisies. Before using calendula oil, check with your doctor if you have allergies.
3. Combined with medications used during and after surgery, calendula use might cause too much drowsiness and should be stopped at least two weeks before surgery.
Side Effects of Calendula Oil
If you are not pregnant, nursing, allergic or about to undergo surgery, you can use calendula oil with likely no side effect. It is best, however, to consult your health care provider before you use it, especially for therapeutic use.
Remember, though, that sedative medications or CNS depressants interact with calendula. The plant extract might cause sleepiness and drowsiness, and taking it with sedative drugs might result in excess sleepiness. Some sedative drugs include clonazepam, (Klonopin), phenobarbital (Donnatal) and zolpidem (Ambien). I advise you to also explore safe, natural ways to get a good night’s sleep.
