Background

Calendula, also known as marigold, has been widely used on the skin to treat minor wounds, skin infections, burns, bee stings, sunburn, warts, and cancer. Most scientific evidence regarding its effectiveness as a wound-healing agent is based on animal and laboratory study, while human research is virtually lacking.

One study in breast cancer patients receiving radiation therapy suggests that calendula ointment may be helpful in preventing skin dermatitis (irritation, redness, and pain).

Evidence

DISCLAIMER: These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.

Radiation skin protection: A study in women receiving radiation therapy to the breast for breast cancer reports that calendula ointment applied to the skin at least twice daily during treatment reduces severe dermatitis (skin irritation, redness, pain). However, this study cannot be considered conclusive due to limitations of its design. Based on this evidence, this approach may be considered in patients who experience radiation dermatitis that cannot be controlled with other therapies.
Grade: B

Ear infection: Calendula has been studied for reducing pain caused by ear infections. Some human studies suggest that calendula may possess mild anesthetic (pain-relieving) properties equal to those of similar non-herbal eardrop preparations. Further studies are needed before a recommendation can be made in this area.
Grade: C

Skin inflammation: Limited animal research suggests that calendula extracts may reduce inflammation when applied to the skin. Human studies are lacking in this area.
Grade: C

Venous leg ulcers: Calendula has been suggested as a possible treatment for venous leg ulcers. Further study is warranted.
Grade: C

Wound and burn healing: Calendula is commonly used on the skin to treat minor skin wounds. Reliable human research is necessary before a firm conclusion can be drawn.
Grade: C
