Calendula is another area the FDA has found fault with our wording. Here are some studies with Calendula:

Conclusion: A close scrutiny of literature on Calendula reveals that three species have been investigated pharmacologically. Pharmacological studies reveal that C. officinalis exhibits antibacterial, antiviral, anti-inflammatory, anti-tumor and antioxidant properties; C. arvensis possesses antibacterial, anti-inflammatory, antimutagenic and hemolytic activities; and C. suffruticosa exhibits antimicrobial activity.
Skin inflammation due to radiation therapy (radiation dermatitis). Early research suggests that applying calendula ointment on the skin might reduce radiation dermatitis in people receiving radiation therapy for breast cancer.
Leg ulcers. Early research shows that applying a 7.5% calendula ointment to the skin speeds up the healing of leg ulcers caused by poor blood circulation.
Anal tears (anal fissures). Early research suggests that that applying calendula to the affected area may reduce pain in people with anal tears who do not respond to treatment with sitz baths and the medication nifedipine.
Diaper rash. Early research suggests that applying a 1.5% calendula ointment to the skin for 10 days improves diaper rash compared to aloe gel.
Burns, cuts and bruises: Calendula tinctures, ointments, and washes are often applied to the skin to help burns, bruises, and cuts heal faster, and to fight the minor infections they cause. Calendula cream is also used to treat hemorrhoids. Animal studies show that calendula helps wounds heal faster, maybe by increasing blood flow to the wounded area and by helping the body make new tissue. There are no scientific studies looking at whether calendula works in humans, but using it on your skin is considered safe. Professional homeopaths often recommend using ointments with calendula to heal first-degree burns and sunburns.
Dermatitis: Early evidence suggests that calendula may help prevent dermatitis, skin inflammation, in people with breast cancer who are undergoing radiation therapy, however, other studies show no effect. Calendula is also a safe and effective remedy for diaper rash.
Traditional Therapies for Skin Wound Healing. Conclusion: Traditional therapies have a wide range of therapeutic properties and, consequently, found different clinical applications, but they cannot permanently substitute the use of high-effective drugs, advanced practices, and innovative cellular therapies. Thus, recent trends are moving to the development of specialized healthcare treatments that involve the combined use of traditional medicine and modern practices/products.
The paper, by L. Parente et al., evaluated the wound healing and anti-inflammatory activity of Calendula officinalis in animal models. This experimental study revealed that C. officinalis possesses anti-inflammatory and antibacterial activities as well as angiogenic and fibroblastic properties acting in a positive way on the inflammatory and proliferative phases of the healing process.
