Calendula officinalis is a group of healing plants in the asteraceae family. They are mostly yellow, but a whole new subset of these plants have popped up lately. From the pretty pastel pinks and yellows of the Zeolites to the bold orange and bright yellow of the Sunset series, these pretty plants pack quite a punch. They are annuals in much of the world but often reseed to come back the following spring.There are quite a few benefits of calendula oil, such as protecting the immune system, eliminating pain, soothing inflammation, aiding skinhealth, speeding healing, preventing chronic disease and preventing premature aging, among others. There are very limited effects of calendula oil, such as skin inflammation, but there are no known toxicities or risks associated with this oil, making it safe for nearly everyone. Pregnant women should consult their doctor before use, as is true with any potent natural oil.
