Once you see calendula blooms, you will never forget their golden ray-like petals that resemble the light of the sun. Seventeenth century botanist, herbalist, and astrologist Nicholas Culpepper linked Calendula officinalis with the astrological sign of Leo. Often associated with the lion, this zodiac sign represents the fire element and the embodiment of a strong heart. Perhaps this is why some use the blooms symbolically to mend a broken heart and as an offering to the grieving. From juices, soups, salves, tinctures, and herbal teas to sacred altars, these sunny blooms brighten up all kinds of herbal rituals.
