Calendula,(calendula officinalis) is both beautiful and easy to grow,
Calendula should be included in any herb gardener's list of must haves. Also
known as pot marigold, this is a wonderful plant for the cooler regions as it
tolerates lower temperatures well. Calendula is an annual. It must be grown
every year but easily reseeds so this may be taken into account when planning a
garden. I find calendula does the best when I let a few plants go to seed and
reseed the area themselves vs planting individual plants every year. This does
increase the chances of strays getting out of the area you wanted calendula to
grow but these are easily pulled up if necessary.
Flavonoids, found in high amounts in calendula, are thought to account for
much of its anti-inflammatory activity. Other potentially important constituents
include the triterpene saponins andcarotenoids.
Investigations into anticancer and antiviral actions of
calendula are
continuing. At this time, insufficient evidence exists to recommend the use of
calendula for cancer. Nevertheless, test tube studies have found antiviral
activity for calendula. The constituents responsible for these actions are not
clear, however, and the relevance of these actions for human health care has not
been established.
How to Use It
A tea of calendula can be made by pouring 1 cup (250 ml) of boiling water
over 1–2 teaspoons (5–10 grams) of the flowers; the tea is then steeped, covered
for ten to fifteen minutes, strained, and drunk. At least 3 cups of tea are
recommended per day. Tincture is similarly used three times a day, at 1/4–1/2
teaspoon (1–2 ml) each time. The tincture can be taken in water or tea. In
addition, prepared ointments can be used topically for skin problems, although
wet dressings made by dipping a cloth into the cooled tea are also effective.
Topical treatment for eye conditions is not recommended, as absolute sterility
must be maintained.
Calendula has been used for medicinal purposes since the 12th century. It
was used historically to treat upset stomachs, ulcers and menstrual cramps,
although no clinical evidence has proven its effectiveness for these conditions.
It was also used to relieve fevers and treat cancer. The flowers have also been
used as a pesticide. This plant is not taken orally for any conditions, except
in homeopathic preparations, in which it is extremely diluted.

Ear infections, or otitis media, can be painful for children; by the age of
seven, 93 percent of children have experienced at least one ear infection,
according to a 2003 article written by Sarrell, Cohen and Kahan in the "Journal
of Family Practice." The University of Maryland states that ear drops that
contain calendula may be used to help treat pain related to ear infections in
children. Sarrell et al write that the main goal for treating otitis media if
there is no systemic infection is to alleviate pain. Calendula may be an
effective treatment for some children.
Calendula has a wide range of medicinal uses. It is a soothing tea for
gastrointestinal problems, healing wash for skin wounds, easily infused into oil
for a healing salve or balm. Great for baby diaper area.
Calendula also has the rare quality of keeping its color during soapmaking.
Unlike most herbal additives, calendula will not turn brown or black in a bar of
herbal soap. Add 1 tablespoon of petals to just enough oil to cover. After your
soap reaches trace, stir in the oil and petal mixture throughout your soap
batch. The bright orange petals will remain bright and offer even soothing
properties to the finished soap. For soapmaking information, find someone
knowledgeable in the craft before undertaking it yourself.
Radiation-Induced Dermatitis
Radiation therapy for cancer can cause dermatitis, which is inflammation of
the skin that may be accompanied by a rash or itching. A 2009 meta-analysis
published in the "Journal of Otolaryngology-Head and Neck Surgery" found that
application of topical calendula prevented dermatitis caused by radiation. If
you are receiving radiation, ask your oncologist or treatment team if calendula
is safe for you to use.
Skin Injuries
Burns, cuts and bruises may be treated with calendula preparations.
Tinctures, ointments and washes made with calendula have been used to encourage
wound healing, ease bruising and also treat infections associated with wounds.
Though the exact mechanism of action is not clear, it is thought that calendula
helps blood circulation and encourages collagen production to heal the skin.
