Since the dawn of civilization, the ligulate florets of the Calendula officinalis L. plant, which are commonly and falsely believed to be the floral "petals", have been employed in herbal medicine. The calendula was a commonly used herbal plant in the medical system of many ancient civilizations. Calendula is a member of the plant family Asteraceae.

This plant is commonly cultivated in gardens as an ornamental herb, being at times known as the pot marigold or the garden marigold in some places. The calendula herb must not be mistaken for plants belonging to the genus Tagetes - which are the true marigolds and very commonly cultivated as garden ornamentals.

A variety of ailments were traditionally treated using the calendula, which has one of the longest history as a herbal medical plant, calendula has often been consumed to treat many different kinds of illnesses, these problems include muscular spasms, persistent fevers, suppression of the menstrual cycle in women, and even in treating cancer of different tissues.

The primary use of this herb, however, has always been in the role of a local topical application to boost healing rate on a wound and to prevent the infection of severe wounds on the body. The calendula is prescribed by most modern herbalists in the form of an herbal tincture, as an herbal infusion, or in ointment form - the remedies are used in healing a variety of skin conditions that range from chapped skin to open wounds on the body.

Extensive clinical analysis and many chemical studies on the calendula flowers have been done till date, a lot of these studies have been carried out in Europe, however, not much of the unique or active principles that account for the physiological effects have been identified and no outstanding mystery compounds were found in these studies.

On chemical analysis, the calendula flowers were found to contain a volatile oil, many bitter chemical principles, different types of carotenoids, a lot of mucilage, plant resin, all kinds of polysaccharides, plant acids and a variety of alcoholic compounds, different compounds such as the saponins and other glycosides, as well as different kinds of sterols.

n many of these general groups of compounds, most of the individual constituents have been identified and chemically analyzed in laboratories. Till the middle of the 1980's, the chemical active principles that were seen to be responsible for calendula's reputed anti-inflammatory and wound healing actions remained a mystery, these purported beneficial effects were observed when the calendula was applied locally to the skin or mucous membranes.

While the anti-inflammatory effects have been attributed to the presence of the compounds such as the saponins and polysaccharides, these two compounds were completely absent in the lipophilic extracts of the calendula. The anti-inflammatory activity displayed by the herb has recently been shown to be heavily influenced by the faradiol monoester present in the purified triterpenoid fraction of calendula flowers - in a CO 2 extract.

The freeze dried extract of calendula flowers were recently studied and the study indicated that the water soluble pigments called flavonoids - or some other components - tended to increase the rate of neo-vascularization in the body and caused deposition of hyaluronan - this compound is a major component of the extra cellular matrix, it is often associated with the formation, the alignment, and the migration of capillaries inside the human body.

The long traditional use of the herb in healing wounds is supported to some degree by the results of this research and thus some scientific evidence can confirm the herbal medication's traditional reputation.

Calendula's carotenoid pigments have some use as coloring agents in many cosmetic products, and the volatile oil found in the flowers is a very useful ingredient in perfumeries, however, not a single one of the many other chemicals identified in the flowers has any medicinal properties that can be said to be better than other remedies.

Two cups of this tea was given to every patient daily and very significant success was seen in the treatment.

The report in the journal also cited results obtained from the second study, where twenty four patients down with chronic non-specific colitis were given a remedy made from a combination of herbs that was made up of equal parts of the root of the dandelion, the St. Johns wort herb, the lemon balm herb, calendula and fennel seeds.

Habitat and cultivation

The calendula is an indigenous plant species of the southern European region. These days, it is cultivated in many temperate regions of the world for use in many processes and is naturalized in temperate North America and Asia.

Ideal soil profiles for the growth of the calendula are light to sandy and moderately rich soils. The soil must be fairly moist with a good drainage without water logging. The calendula tolerates a pH range from an acidic 4.5 to a very alkaline 8.3.

For best growth, the calendula prefers sites with full exposure to sunlight, though the herb will tolerate light shade.

The calendula is very easily grown from stored seed. The seeds of the calendula can be sown in the garden on the advent of spring, only when all danger from late frost has disappeared. The calendula seeds can be planted to a depth of six mm or a quarter inch deep in the soil. The seedlings of the calendula normally emerge from the soil in eight to twelve days time.

Once they germinate, calendula seedlings must not be subjected to transplantation, as this procedure mostly results in the wilting and death of the large succulent leaves. When the seedlings emerge, they can be thinned out so that forty to fifty cm-16 to 20 inches of space exist between each of the plants.

This spacing will result in optimum utilization of space by the growing plants. When the calendula plants are growing, the side branches must be pruned away from time to time to encourage taller growth and to induce larger blooms in the plants.

To keep the plants in full bloom throughout the summer, the dead flower heads must be removed from each plant from time to time. These measures will ensure that the plants grow at an optimal rate and produce the best flowers. Calendula plants will self sow if they are left undisturbed at a site where they are growing. The calendula is normally free of plant pests and resistant to diseases.

The calendula can be placed in pots for keeping inside the house in midsummer. Plants must be brought indoors several days in advance before the estimated coming of the first frosts in the fall. When calendula plants are placed indoors, the plants will need a minimum of five hours exposure to direct sunlight daily, which can be substituted by twelve hours of exposure to strong artificial light a day. As root rot can result from excess water, plants must not be watered too often. Ideally, the soil in the pot must be kept moderately moist at all times.


Calendula contains saponins, flavonoids, mucilage, essential oil, bitter principle, resin, steroidal compounds.

Usual dosage

Herbal calendula tea can be prepared by steeping one to two teaspoons of the flowers in two hundred ml of boiling water; the pot must be covered for ten to fifteen minutes to allow the herb to infuse into the water.

Once this is done, the decoction can be strained, cooled and then drunk as and when needed. Generally, a minimum of three cups of the herbal calendula tea must be consumed everyday to get the beneficial effects.

OIL - To alleviate nervous anxiety or depression, add five to ten drops of the oil in bath water and bathe daily or as long as necessary.

Collection and harvesting

Only the tender and young leaves must be picked and only freshly plucked leaves must be used to prepare remedies. As for the calendula flowers to be used fresh or dried for late use, the floral petals must be collected only from flowers that have just opened.

When fresh flowers are to be used in culinary or medical preparations, the first thing to be do is to pluck the petals from the flowers in one clean action, the white or pale green "heels," on the flowers that have a somewhat bitter taste must then be cut off, the freed petals can then be washed gently in water, and then dried well using tissues.

One more way to do this is to wash the collected flowers initially; followed by the plucking out of individual petals, and lastly a drying session using paper towels to pat dry the wet petals. Once the petals have been washed, they can be stored wrapped in plastic bags in the refrigerator for use as and when they are needed.

After harvesting, the calendula flowers that need to be dried can be spread thinly on screens inside a dark, warm and well ventilated site. If the air flow is poor while the petals are being dried, they tend to lose their color and flavor, therefore proper ventilation in the site is a must for drying the flowers. While they are being dried, the flowers must frequently be turned till they become crisp to the touch.

Separate the petals from the flowers once they become dry and then store these in an airtight container for use as and when needed. Due to the fact that the dried calendula petals tend to absorb moisture, they must be absolutely dry before storage - moisture can destroy the dried flowers. When preparing remedies from the dried petals, one way to use them is to ground them well and to use the powder to make the herbal remedy.

Calendula is my favourite herb. I always have it in my first aid kit. I use calendula infusion as a gargle for any inflammation in the mouth and sore throat. Just pour a glass of boiling water over 1 tablespoon of dried calendula petals and brew covered for about 10 minutes. Then strain the decoction and rinse your mouth. You can also drink this decoction, half a glass once a day. I also drink calendula tea for stomach problems. A wonderful herb also for the skin (skin eruptions and insect bites). Calendula ointment is great for deep scratches and burns.
From Nina P. - May-08-2015
I make calendula oil by steeping flowers of calendula in soya bean oil for 40 days. Just fill a dark bottle with flowers and add as much oil as it can take. I use flowers from my own garden, without chemicals. This oil is excellent for hydration and with it we successfully treated my nephew's eczema when he was 3 yrs old. We added calendula oil in his bath water.
