What is calendula used for?

Calendula has been used to treat various skin conditions, as well as infections and fungi. Research shows that calendula may be effective in treating diaper rash, wounds, vaginal yeast infections, and other skin conditions. Calendula has also been used to relieve pain and inflammation. It has also been used as an adjunct in cancer treatment, especially for treatment-related side effects (such as radiation).

Some research suggests that calendula may be helpful as a sunscreen. Others use calendula simply as a moisturizer.

While there is some research to suggest positive effects of calendula, the long-term use of calendula has not been studied and more research is needed. Always check with your healthcare professional before starting treatment or taking supplements.

How does it work

The active ingredients in calendula flower are natural chemicals such as triterpenic saponins (oleanolic acid glycosides), triterpenic alcohols (α-, β-amyrins, faradiol), and flavonoids (quercetin and isorhamnetin).

The photoprotective effect of topical gel formulations is believed to be associated with improved collagen synthesis in subepidermal connective tissue. The chemicals in calendula are believed to accelerate the growth of new tissue during wound healing and reduce inflammation.

Wounds and bedsores

Animal studies have shown a link between calendula consumption and better wound health. And the people? A recent study published in the Journal of Family Medicine and Primary Care examined the efficacy of calendula ointment for cesarean section in 72 women.

The researchers found that, compared to standard hospital treatment, women who were treated with calendula ointment had faster healing times. They reported that their incisions were less red and less swollen.

In a 2016 study published in The Journal of Wound Care, researchers used calendula officinalis extract to treat people with venous leg ulcers. Their results showed that those who were treated with calendula had a "cure rate per week" of 7.4%, compared to 1.7% in the control group. Furthermore, the researchers reported that "no side effects were observed during treatment with calendula officinalis extract."

Early research suggests that using a calendula spray in addition to standard care and hygiene can prevent infection and reduce odor in people with chronic foot ulcers from diabetes .

Eczema, diaper rash, and other skin conditions.

Calendula is widely used to treat eczema and dermatitis ; however, research on calendula for eczema and dermatitis is limited. Since the plant has anti-inflammatory properties, applying it to the skin can reduce inflammation. However, there is no real clinical evidence to support its use for eczema.

In fact, the use of calendula can be irritating to young children with severe eczema, especially if they are allergic to ragweed, chamomile, calendula, or any other plant in this family.

The use of calendula in children may be contraindicated, so always consult your doctor before starting.

Using calendula creams for diaper rash may be more effective than some treatments, such as aloe vera gel. However, research shows that calendula is inferior to bentonite solution. The researchers found that when the babies were treated with bentonite, 88 percent of the lesions in the bentonite group began to improve within the first six hours, compared with 54 percent in the calendula group.

Bacterial vaginosis and vaginal yeast infections

The researchers compared the use of calendula ointment with metronidazole (a common drug used to treat bacterial vaginosis) in 80 women diagnosed with bacterial vaginosis . They found that after a week of intervention, both groups of women were cured of bacterial vaginosis and neither of them had any side effects.

They concluded that for those women who would not want to take medication to treat bacterial vaginosis, calendula ointment may be a viable option. Regarding its effectiveness in treating yeast infections, a study published in the journal Women and Health found that calendula cream was effective in treating vaginal yeast infections, but had a delayed effect compared to standard medications. (clotrimazole).

While there have been claims that calendula can be used to treat menstruation, there is no additional evidence to support such use.

Calendula as a sunscreen

Calendula's effectiveness as a sunscreen has been tested in vitro (i.e., in a Petri dish or test tube) . The idea behind this study is that calendula's cell rejuvenating properties can also be used as a sunscreen. More research is needed in this area. Therefore, it is advisable to use an approved UV protection sunscreen.

Radiation dermatitis

There is mixed research on whether applying calendula to the skin can reduce radiation dermatitis (skin irritation) after radiation therapy. It may not be better than petroleum jelly (petroleum jelly), but more research is needed.

Possible side effects.

You should not use calendula if you are allergic to ragweed, chamomile, calendula, or Asteraceae / Asteraceae. This can cause an allergic reaction.

Pregnant or lactating women should also avoid using calendula, as consuming calendula can affect hormone levels and cause menstruation .

Anyone who is taking medication or scheduled for surgery should first discuss the use of calendula with their doctor.
