Calendula Infused Oil
Calendula is good for any skin type but especially dry, acne-prone or aging skin, soothing, cooling and plumping it up. To use it, you can make a calendula infused oil. Fats and oils extract the oily and resinous properties of an herb, and these are often the antibacterial, antifungal and wound-healing components. To make a cold infused oil cut up the herb and cover with vegetable oil (olive, sunflower etc.) in a glass bottle or jar, Leave on a sunny windowsill for 2 weeks, shaking daily. Strain into a clean jar. Infused herbal oils may be used as they are, applied directly to the skin. Unlike essential oils, they do not need to be diluted for use.
You can also thicken your oil into a salve by warming it gently, and adding beeswax. When the beeswax has melted, remove from the heat and pour into clean glass jars. The more wax you add, the harder the set. This will keep at least a year.
