The bright orange petals of the calendula plant have been used for many centuries in herbal preparations. Medieval monks used it to treat insect and snake bites. During the American Civil War, the flowers were used in numbers by doctors in their treatment of open wounds. Its use as a very able antiseptic helped to stem bleeding, aided in the prevention of infection, and quickened the healing process.
Its flowers are still used today by herbalists for varied health benefits. The natural chemicals found in calendula help with healing by increasing the flow of blood to the wounded area, and also by advancing the production of collagen proteins.
The high amount of flavonoids found in the plant, are believed to be the reason behind its anti inflammatory capabilities. Flavonoids are natural chemicals, and act as anti-oxidants to protect from damage caused by oxygen free radicals.
