What is calendula?
Calendula (Calendula officinalis), also known as pot marigold, is most used as a topical anti-inflammatory and antiseptic. It contains antioxidants, flavonoids, and terpenoids that likely contribute to its anti-inflammatory effects. Its antiseptic effects are not as reliable. It has also been used less often to treat and prevent gastric ulcers, and to help lower blood sugar. Calendula is most often used in dogs, cats, and horses.

Dietary supplements are substances that can be used to supplement the diet, such as vitamins, minerals, amino acids, herbs, botanicals, enzymes, and probiotics. While many supplements are sold over the counter, they still contain ingredients that have biological effects that should be managed by your veterinarian. Follow your veterinarian’s directions and cautions very carefully as their directions may be significantly different from those on the label.
There are differences in how countries regulate supplements. In the United States, these substances are not as vigorously regulated by the FDA as other medications, which means they can be sold without the manufacturer proving their effectiveness, safety, and without a guarantee of consistent or accurately reported ingredients. In Canada, products that have been evaluated for quality, safety, and effectiveness by Health Canada and authorized for sale will have a license number on the label.
How effective is calendula?
Limited studies in animals have been performed, but there is anecdotal evidence that calendula works to support skin healing by treating inflammation.
