The medicinal effects of calendula oil against eczema?

The use of botanical extracts as anti-inflammatory medicine is a common practice among patients suffering from eczema who are seeking "natural" remedies, particularly in response to the failure or intolerance of certain medicinal treatments. Calendula oil is often mentioned as a relief for eczema problems. But what about its effectiveness on this skin condition?

Does calendula oil truly have an effect on eczema?

The calendula was first used before the 12th century for its anti-inflammatory and soothing properties. It is widely believed that its use can be beneficial in the treatment of eczema. Indeed, its application on affected areas would help to reduce inflammation. However, the exploration of calendula in the treatment of eczema is limited. Although a few studies have shown that calendula had an effect in the treatment of certain skin disorders, there is, however, no real evidence of the effectiveness or safety of using calendula on eczema.

A randomized double-blind clinical trial (n = 66) demonstrated that the use of a calendula ointment on children under 3 years old suffering from diaper rash, a common type of dermatitis in infants and children characterized by an acute inflammatory reaction in the area covered by the diaper, was more effective than a cream with aloe vera, as evidenced by fewer rash sites after 10 days of application 3 times a day. However, other research has shown that it was not as effective as the use of bentonite, a type of natural clay rich in minerals.

reduce redness, severity, and the extent of the area affected by infant diaper dermatitis, often caused by babies' wet diapers, thanks to its anti-inflammatory properties. Additionally, you can find it in some over-the-counter diaper rash creams.

Similarly, a randomized phase III clinical trial was conducted to evaluate the effectiveness of Calendula officinalis compared to trolamine (Biafine) in preventing erythematous radiodermatitis induced during breast cancer radiotherapy, the severity of which varies from mild erythema to severe erythema. 254 patients who had undergone surgery for breast carcinoma and were due to receive post-operative radiotherapy (conservative surgery or mastectomy) were randomly divided between the application of an ointment containing 20% calendula in petroleum jelly (126 patients) and the application of trolamine (128 patients) on the irradiated areas after each session. The occurrence of acute grade 2 or higher dermatitis was significantly lower (41% versus 63%) with the use of calendula than with that of trolamine. Furthermore, patients receiving calendula less frequently interrupted radiotherapy and the pain induced by radiation was significantly reduced.

These various studies suggest that the topical application of calendula could serve as a treatment for diaper rash and as a preventive treatment for the onset of radiation-induced dermatitis, effects attributed to its anti-inflammatory properties. It is then likely that calendula may also improve eczema, although further research on the therapeutic effects of calendula on this inflammatory skin disease is highly recommended.

By what mechanisms?

The effects achieved with calendula could be attributed to its anti-inflammatory propertiesmechanism of action is poorly understood , the flavonoids and saponins found in calendula could prevent the release of enzymes and histamine that cause sensitivity and inflammation, and could help soothe redness and pain. At the same time, it could reduce the migration of white blood cells to the inflamed area by decreasing the permeability of blood capillaries, due to the presence of triterpenoids.
