Calendula has been used in countless salves as a primary ingredient for skin rashes, diaper rashes, minor cuts, chapped lips, and minor burns. A strong tea made from the flowers makes an excellent foot soak for athlete's foot, a facial wash for acne, or a mouth wash for canker sores.
To make a Calendula Salve first make an infused oil by covering the 1/4 cup of flowers in 1/2 cup of extra virgin olive oil in a closed jar for at least two weeks. After two weeks the oil should have turned a darker yellowish color. Strain off the flowers through a muslin cloth and pour oil into a stainless steel or pyrex pot. Heat oil on low and grate about 1/8 cup of beeswax. After it has melted take off heat and add 40 drops of essential oils (I would add Lavender). Pour into the jar you intend to keep the salve in and store in a dark, dry place. This salve should last at least a year if not longer if stored properly.
