Calendula

Updated on November 15, 2020

Scientific: Calendula officinalis [WikiPedia]

Composition: The active constituents in calendula are saponins, carotenoids, bitter principles, essential oils, sterols, flavonoids, mucilage and tocopherols. The fresh plant also contains salicylic acid which acts as an analgesic.

Appearance: This herb is known as pot marigold. The bright yellow, orange, or red-orange flowers of calendula are a familiar sight in gardens and landscape designs found all over the world. The small plant seldom exceeds 18 inches in height.

Parts Used: Flowers

Common Uses: Calendula is very commonly used in herbal medicine as a topical anti-inflammatory and antiseptic. Its soothing effect is due to its ability to scavenge free radicals (which are products of inflammation), preventing them from causing further inflammation, and to its ability to inhibit lymphocyte proliferation (a white blood cell associated with the immune system). Flavonoids and possibly terpenoids are believed to contribute to these effects. Calendula also is credited with an antiseptic effect, but this effect appears to be very weak and does not alone warrant its current use in humans as a mouthwash and dentifrice. Calendula is, however, a potent molluscicide, meaning that it is lethal to snails, slugs and flukes.

A less commonly known effect of calendula is its ability to heal and prevent gastric ulcers, due to its content of saponins. Calendula also delays gastric emptying and lowers blood sugar, effects that are of potential importance as veterinary and human medical practitioners become increasingly concerned about insulin resistance and its multiple adverse effects.

Alternatives and Adjuncts: For first-aid, combines well with Saint-Johns-wort. Increase effectiveness in antifungal applications, add bee balm, Oregon grape or licorice. Urinary and digestive tract inflammation, combine with corn silk, marshmallow or plantain.
