Calendula

What is it?

Calendula (Calendula officinalis) is a plant known as pot marigold. It is not the same as ornamental marigolds of the Tagetes genus grown in vegetable gardens.

Calendula is native to Asia and southern Europe and has been traditionally used in Ayurvedic and Unani systems of medicine. The chemicals in calendula might help new tissue grow in wounds and decrease swelling in the mouth and throat.

Calendula flower is commonly used for wounds, rashes, infections, inflammation, and many other conditions. But there's no strong evidence to support the use of calendula for any purpose.

How effective is it?

There is interest in using calendula for a number of purposes, but there isn't enough reliable information to say whether it might be helpful.

Is it safe?

When taken by mouth: Preparations of calendula flower are likely safe for most people.

When applied to the skin: Preparations of calendula flower are likely safe for most people.

Special precautions & warnings:

Pregnancy: Don't take calendula by mouth if you are pregnant. It is likely unsafe. There is a concern that it might cause a miscarriage. It's best to avoid topical use as well until more is known.

Breast-feeding: There isn't enough reliable information to know if calendula is safe to use when breast-feeding. Stay on the safe side and avoid use.

Allergy to ragweed and related plants: Calendula may cause an allergic reaction in people who are sensitive to the Asteraceae/Compositae family. Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many others. If you have allergies, be sure to check with your healthcare provider before taking calendula.

Are there interactions with medications?

Moderate
Be cautious with this combination.
Sedative medications (CNS depressants)
Calendula might cause sleepiness and slowed breathing. Some medications, called sedatives, can also cause sleepiness and slowed breathing. Taking calendula with sedative medications might cause breathing problems and/or too much sleepiness.

Are there interactions with herbs and supplements?

There are no known interactions with herbs and supplements.

Are there interactions with foods?

There are no known interactions with foods.

How is it typically used?

There isn't enough reliable information to know what an appropriate dose of calendula might be. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult a healthcare professional before using.
