Calendula (Calendula officinalis) is recognized for its antiseptic and anti-inflammatory properties. It is considered one of the most effective herbal remedies for skin problems, such as wounds, rashes, chapped hands, and infections. Calendula is also traditionally used to treat spasms, fever, suppressed menstruation, and other health conditions.

The calendula plant is grown throughout Europe, Western Asia, and the United States. Calendula is an annual (needs to be replanted each year) that thrives in any soil.

Dried flowers are the most important part of the calendula for medicinal purposes.

Calendula is used to treat the following conditions and symptoms:

• Inflammation of the mouth and throat
• Wounds
• Burns
• Leg ulcers
• Dry, chapped skin
• Skin rashes

Calendula is available in the following forms:

• Fresh or dried leaves and florets
• Tinctures
• Liquid extracts
• Infusions
• Ointments
• Creams

Calendula products should always be protected from light and moisture, and should not be stored for more than three years.

Recommended doses are as follows:

• Infusion: 1 tsp dried florets in 8 oz water; steep 30 to 40 minutes; drink two to three cups per day
• Fluid extract (1:1 in 40% alcohol): 0.5 to 1.0 ml three times per day
• Tincture (1:5 in 90% alcohol): 2 to 4 ml three times per day
• Ointment: 2 to 5 g crude drug in 100 g ointment

Frequent skin contact may result in sensitivity. Calendula is also known to affect the menstrual cycle and should not be used during pregnancy and breast-feeding.

No noteworthy interactions (positive or negative) between calendula and conventional medications are known to have been reported in the literature to date.
