2. Anti-Inflammatory Properties

One of the most significant benefits of Calendula is its ability to reduce inflammation.

Calendula is widely used in topical applications for its wound healing abilities.

• Promoting Tissue Repair: Research in the "Journal of Ethnopharmacology" has shown that Calendula stimulates tissue regeneration and granulation, essential for effective wound healing【2】.
• Use in Post-Surgical Healing: Its ability to accelerate wound closure and reduce scarring makes it useful in post-surgical care, as noted in studies focusing on cesarean section and perineal tears.

4. Antimicrobial Effects

Calendula also possesses antimicrobial properties, enhancing its effectiveness in wound care.

• Fighting Infection: The "Journal of Basic Microbiology" reports that Calendula extracts have antimicrobial activities against various bacteria, fungi, and viruses, preventing wound infections【3】.

5. Oral Health Applications

Besides its skin benefits, Calendula is beneficial in oral health.

• Treatment of Oral Inflammation: Its anti-inflammatory properties are effective in treating gingivitis and other forms of oral inflammation. A study in the "International Journal of Dental Hygiene" found Calendula effective in reducing dental plaque and gingival inflammation【4】.

6. Calendula in Oncology

Emerging research suggests Calendula's potential in oncology, particularly in managing radiation-induced skin damage.

• Radiation Dermatitis: A study in the "Journal of Clinical Oncology" found that topical application of Calendula reduced the incidence of grade 2 or higher acute dermatitis during radiation therapy for breast cancer【5】.

7. Safety and Dosage

Calendula is generally safe when used appropriately.

• Recommended Dosage: While there is no standard dosage, it is important to follow product-specific recommendations or consult with a healthcare provider.
• Side Effects: Calendula is well-tolerated, but allergic reactions may occur, especially in individuals sensitive to the Asteraceae/Compositae family.
