  10. Medicinal Properties • Used as a lotion to alleviate sprains and wounds, and for inflamed eyes [8] • Folk healers used it to induce menstrual flow and cure jaundice [7,9] • 19th century American physicians used it to treat liver problems and conjunctivitis [9]

  11. Medicinal Properties Cont’d • “Demonstrates astringent and anti-inflammatory activity [10,11].” • Some herbalists recommend the plants oils as a treatment of yeast infections [6]. • Preparations have been used for “skin and mucous membrane inflammations (such as pharyngitis and leg ulcers) [4,6].”

  12. Calendula Constituents • Polysaccharides, • Proteins, • Fatty acids, • Flavonoids, • Triterpenoids, • Saponins [20] • Carotenoids [17] • Main pigments: • flavoxanthin • Lutein • Rubixanthin • β-carotene • γ-carotene • lycopene.

  13. Adulterants • No found adulterants, but… • Used as an adulterant in saffron [21]

  14. Pharmacology • Calendic acid is the omega-6 fatty acid chain present in Calendula which is one of the factors that gives Calendula officinalis its medicinal properties.

  15. Pharmacodynamics • Laser activated Calendula extract shows inhibition of cell proliferation in G phases of cell cycle [20] • High levels of enzyme activity (especially naphthol-AS-BI-phosphohydrolase and acidic phosphatase) found in fresh juices of the plant [22] • “therapeutic effect might be directly related to the quantity and activity of plant enzymes” • Pharmacokinetics: Couldn’t find any studies on ADME (absorption, distribution, metabolism, and excretion)

  16. Contraindications • Very few concerns and warnings in regards to Calendula, however: • “Internal use of Calendula preparations should be avoided during early pregnancy due to its ability to cause menstruation [12].” • “Allergic hypersensitivity may be an issue for persons sensitive to Calendula or to other members of the Asteraceae family [12].’

  17. Calendula has shown promise in numerous arenas such as antimicrobial, anti-HIV, and wound healing [4,7]. One in vitro study stated that B-calendic acid showed anti-cancer properties against malignant colon cells [13]. Research

  18. In vitro Studies • Antioxidant Properties [15] • possessed better scavenging and antioxidant activity than Calendula arvensis • Water extracts had the best antioxidant properties; 0.75 mg/ml extracts completely eliminated hydroxyl radical • Genotoxic and Chemopreventive properties [16] • Aqueous and ethanol extracts of Calendula officinalis showed reversion of diethylnitrosamine unscheduled DNA synthesis (DEN effect) • “Concentrations producing genotoxic damage were three orders of magnitude above concentrations that conferred total protection [from DEN effect]” • Anti-tumor therapeutic effect: cytotoxic tumor cell activity and lymphocyte activation [20] • 70-100% inhibition of tumor cell proliferation when tested on a wide variety of human and mouse tumor cell lines • Non-Laser Activated Calendula Extract only produced slight tumor inhibition (they think it’s excited carotenoids)

  19. Animal Studies • Anti-tumor & Anti-Inflammatory Properties[14] • Triterpenes are thought to be the reason for these properties • taraxastanes and helianol levels lead to inhibitory effects of inflammation of mouse ears

  20. Clinical Trials • Highly effective for the prevention of acute dermatitis of grade 2 or higher [18] • Single blind study • occurrence of acute dermatitis of grade 2 or higher was significantly lower (41% v 63%; P .001) using calendula instead of trolamine. • less frequent interruption of radiotherapy and significantly reduced radiation-induced pain. • more difficult to apply, but self-assessed satisfaction was greater • should be proposed for patients undergoing postoperative irradiation for breast cancer.

  21. Clinical Trials Cont’d • Reduces pain of acute infection and inflammation of the middle ear in children [19] • Concluded “an herbal extract solution may be beneficial” in treatment of ear pain • Administered to 180 children, double blind • Best effects were the [calendula officinalis flores (28%), hypericum perforatum herba tota (30%), and verbascum thapsus flores (25%) in olive oil and the essential oils allium sativum in 0.05% in olive oil (10%), lavandulla officinalis (5%), and tocoferol acetate oil (2%)] with amoxicillin • Concludes that the findings did not account for a lot of the pain resolution and best idea for physicians is to prescribe 3 days to give the body “a chance to repair itself”

  22. Conclusions • There is definite proof that ointment containing Calendula officinalis helps prevent skin irritation, redness, and pain • Pain-relieving properties may be present, but more studies are needed to investigate this possibility • There hasn’t been many animal studies to prove that it really does reduce skin inflammation • There need to be clinical trials to determine if it helps with wound and burn healing
