Herbal Calendula may have a strong effect on speeding up wound healing, according to studies by a number of institutes.
Wound healing is a natural process of our body by restoring the function of the damaged or injured tissue through several stages.
Most importantly, the early stage of wound healing is also known as the acute phase of infection, which starts as soon as the immune system senses the tissue damage by stimulating the blood vessels to provide the damaged tissue with blood palette to cover the wound temporarily and activated the proteins associated with the production of inflammatory cytokines to the site of infection with an aim to kill off all micro invaders.
In most cases, the immune first line of defense can destroy the pathogens and speed up the recovery of the damage by inducing fiber tissue reconstruction, and new blood vessels.
However, overproduction of a proinflammatory cytokine in this phase may cause damage and death of nearby cells, leading to the formation of scars.
If the immune system can not kill off all the invaded pathogens within a set of times, normally in 3-8 weeks, it will adapt to the new change, leading to low-grade inflammation, a major cause of several chronic ailments, including diabetes, and heart diseases.
If the process of wound healing is disrupted, it may also lead to improper wound healing with complications, including inadequate scar formation, excessive scar formation, contracture formation, and an exaggeration of normal wound edge contraction forming deformities.
Calendula is also known as pot marigold, an annual or perennial herbaceous plant of about 12–20 species of the genus Calendula, belonging to the family Asteraceae, native to Southern Europe. It has been used in herbal medicine for spasmolytic, spasmogenic, and inflammatory effects and for the treatment of abdominal cramps, wound healing, skin diseases, colitis, constipation, etc.
Besides major chemical constituents of triterpenoids, flavonoids, coumarins, quinones, volatile oil, carotenoids, and amino acids, the herb also contains loliolide (calendin), calendulin, and n-paraffins.
Researchers on finding a natural ingredient for speeding up wound healing examined the effect of Calendula officinalis, an annual herb from the Mediterranean origin which is popularly used in wound healing and as an anti-inflammatory agent.
Injection of C. officinalis demonstrated significant anti-inflammatory and antibacterial activities in protecting the wound against infection.
Furthermore, C. officinalis also speed up the wound healing process by enhancing the angiogenic and fibroblastic properties.
The findings strongly suggested that herbal Calendula can act in a positive way on the inflammatory and proliferative phases of the healing process.
Moreover, in the evaluation of the effects of oral and topical application of Calendula officinalis flower extract on excision wounds made in rats, compared to the control of 51.1%, oral and topical application of Calendula showed a wound closure was 90.0%.
The extract treatment at a dose of 20 or 100 mg/kg b.wt reduced the period needed for re-epithelization to 14 and 13 days, respectively compared to 17.7 days in the control.
Additionally, the extract-treated group also exhibited a significant increase in the concentration of collagen. compared to untreated animals.
Interestingly, in a total of 36 rats and 90 embryonated eggs used to evaluate healing and angiogenic activities of extracts and fractions of Calendula, through the induction of skin wounds and the chorioallantoic membrane, respectively, researchers found that
* Injection of calendula extract exerted an angiogenic activity in speeding up wound healing in both experimental models.
* The efficacy was not attributed to the signal protein produced by cells that stimulate the formation of blood vessels, but to other unknown pro-angiogenic factors.
Taken altogether, herbal Calendula may be considered a functional remedy for speeding up wound healing with no side effects.
