Beloved comfrey, mender of wounds. A native of Europe and Asia, comfrey has historically been a pain reliever, anti-inflammatory, and wound healer. Comfrey is considered a natural anti-aging powerhouse as it contains both allantoin and rosmarinic acid. Allantoin is wonderful for giving skin a plump, glowing look. It can minimize the appearance of fine lines and wrinkles, while rosmarinic acid provides pain relief and reduces redness from inflammation.
