The calendula flower, also called a pot marigold, is one of our favorite “herbal allies.” We grow it locally ourselves, and harvest the remainder from local farms in Sonoma county. When harvesting, we notice our hands tend to get a little sticky: that’s because all the good stuff is contained in a resin at the base of the flower head, which is why we always use the full blossom in our products (peep them floating around our flower child toner).
Calendula has demonstrated anti-inflammatory properties and is a proven wound-healer for skin abrasions and burns.  It’s also a great anti-bacterial, meaning it helps fight breakouts. Preliminary studies suggest it might exhibit anti-tumor activity as well.
