Before using calendula for medicinal purposes, it's advisable to consult with a healthcare professional, especially if you have any existing medical conditions or if you're pregnant or breastfeeding. While calendula is generally considered safe for most people when used topically, some individuals may experience allergic reactions.
Chemical composition of Calendula
Calendula contains various compounds that contribute to its medicinal properties. Some of the key chemical constituents found in calendula include:
Triterpenoids: Calendula contains compounds such as faradiol esters, which have anti-inflammatory properties and contribute to wound healing.
Flavonoids: These are antioxidants present in calendula, such as quercetin and isorhamnetin, which help protect the body from oxidative stress and inflammation.
Carotenoids: Calendula petals contain carotenoids like lutein and beta-carotene, which give the flowers their vibrant color and have antioxidant properties.
Saponins: These compounds may contribute to the antimicrobial and anti-inflammatory effects of calendula.
Polysaccharides: Calendula contains polysaccharides that have immune-stimulating properties and may contribute to its wound-healing effects.
Oleanolic Acid and Ursolic Acid: These are triterpenoids found in calendula with anti-inflammatory and antimicrobial properties.
The specific composition of calendula can vary depending on factors such as the plant's growing conditions, extraction methods used, and the part of the plant being utilized (flowers, leaves, or stems). The combination of these compounds is believed to contribute to the plant's various medicinal benefits, including its ability to soothe skin irritations, promote wound healing, and exhibit anti-inflammatory and antimicrobial effects.
Potential drug, supplement, and nutrient interactions
Calendula is generally considered safe for most people when used topically in appropriate amounts. However, there might be potential interactions with certain medications or nutrients when ingested orally or used in concentrated forms. Here are some considerations:
Anticoagulant/Antiplatelet Drugs: Calendula may have mild anticoagulant properties. When taken in large amounts orally, it could potentially increase the risk of bleeding or interact with medications like warfarin (Coumadin) or aspirin. It's advisable for individuals taking these medications to consult a healthcare professional before using calendula supplements.
Diabetes Medications: There's limited evidence suggesting that calendula might lower blood sugar levels. People with diabetes who are taking medications to control blood sugar should monitor their levels closely when using calendula products to avoid hypoglycemia. Consulting a healthcare provider is recommended.
Sedatives: Calendula might have mild sedative effects. When taken along with sedative medications, it could potentially increase drowsiness. Caution is advised if combining calendula with medications that cause drowsiness or sleepiness.
Herb-Drug Interactions: Calendula is an herb that might interact with other herbs or supplements. If you're using multiple herbal supplements, it's a good idea to consult a healthcare professional to avoid potential interactions.
Allergies: Individuals who are allergic to plants in the Asteraceae family (such as ragweed, daisies, marigolds) might also be sensitive to calendula. Allergic reactions could include skin irritation, rash, or respiratory issues. It's essential to perform a patch test or consult a healthcare provider if there's a known allergy.
Always inform your healthcare provider about any supplements, herbs, or natural remedies you're using, including calendula, especially if you're taking prescription medications. This helps prevent potential interactions and ensures safe and effective healthcare management.
