Harvesting Guidelines

Calendula blooms nearly continuously from spring through fall; picking the blossoms every 2-3 days helps to encourage additional blooms . Harvest flower heads (in full flower) in the afternoon after the dew has evaporated and dry in a warm, well-ventilated area .


Calendula has sunny yellow and orange flowers that open in the morning when the sun rises and close as it sets.

Calendula, also known as marigold, gets its name from the ancient Roman calendar, where it was noted to bloom on the first day of each month. In Italy, it is called fiore d'ogni mese, meaning "flower of every month," and in France, it is known as fleur de tous les mois. While many herbal books attribute the use of calendula to ancient Greek and Roman sources, there is debate among scholars as to whether the flower mentioned in these sources is the same as calendula. Therefore, we will not include these early sources here.

Calendula has a long history of use as a healing herb, particularly for wounds and skin issues. It has been used both externally and internally for various illnesses, with some folk herbalists using it in combination with other treatments for maximum effectiveness. Even homeopathic practitioners, such as Samuel Hahnemann, recognized the benefits of calendula for topical infections, wounds, sores, and burns. During times of war, calendula was often used as a last resort for treating wounds when other medical supplies were scarce. While there have been few clinical trials on calendula, the available research supports its traditional use as a vulnerary, or wound-healing agent. Further studies are needed to fully understand the potential benefits of calendula.(1)

Calendula, also known as marigold, has been approved by Germany's Commission E for both internal and topical use. It has been found to be effective in reducing inflammation of the oral and pharyngeal mucosa, as well as promoting healing of slow-healing wounds. Clinical studies have also shown that calendula can be useful in preventing skin toxicity and irritation caused by radiation therapy, and can improve the severity of diaper rash due to its anti-inflammatory and antimicrobial properties. As a result, calendula is a common ingredient in natural diaper rash products.(2)

Calendula has been used for centuries for its medicinal properties. It is believed to have lymphatic cleansing properties, helping to remove toxins from the lymphatic system and decongest swollen lymph nodes. Additionally, it is thought to improve blood circulation and aid in internal drainage from wounds, indicating its affinity with the lymphatic system and veins. Calendula is a versatile herb that has been used in various forms, including teas, tinctures, and salves, for its healing properties. (3)
