Calendula (Calendula officinalis) is a well-known medicinal herb and uplifting ornamental garden plant that has been used therapeutically, ceremonially, and as a dye and food coloring since at least the 12th century. Most commonly known for its topical use, calendula has been shown to help wounds heal faster, possibly by increasing blood flow and oxygen to the affected area, which helps the body grow new tissue. It is also used to improve skin hydration and firmness. The dried petals of the calendula plant are used in tinctures, ointments, and washes to treat burns, bruises, and cuts, as well as the minor infections they cause. The fresh plant can be prepared as a tea or tincture and the fresh flowers of calendula plant are edible.
