I was wrong.
Turns out it really is simple to turn these lovely flowers:
It didn't even cost much. I paid a whopping 9 cents for the flower seeds (on clearance in May, even though they weren't supposed to be planted until June or July in these parts). The beeswax I've had so long I don't remember how much I paid for it, but I don't think it was much, since I bought it right from a beekeeper (I'm hoping that by the time I run out, I'll have convinced my hubby that I should have a beehive somewhere so we don't have to pay for anymore honey, beeswax or any other bee products we might wish to use). I used a generic olive oil, so that cost about $0.75 for this batch. I'm not even sure how little the drops of tea tree oil and vitamin E oil cost, but it has to be pennies.
I chose to use tea tree oil and vitamin E oil because A) they are natural preservatives so I should be able to use what I make until it runs out, however long that should be; and B) because I feel they give the salve some extra umph. Tea tree oil is excellent for just about any skin problem whether it be fungal, bacterial, viral, insect-al (pretty sure that isn't a word, but it soothes bug bites and stings, so I'm using it), rashes of mysterious origin, burns, cuts, scrapes, and more. Vitamin E helps prevent scars, so I thought that would be nice to throw in too.
Calendula salve1 cup calendula petals
1/2 cup olive oil
2 tbsp grated beeswax
10 drops tea tree oil
10 drops vitamin E oil
Gently simmer calendula petals in olive oil in a glass or stainless steel pan for 2 hours (take care that it never reaches a full boil or you are likely to have serious problems), stirring occasionally with a wooden spoon. Strain petals out of oil using a piece of cheesecloth or fine strainer. Melt beeswax in a double boiler (I actually just wiped the remaining petals out of the pan I'd been using and let the heat of the pan melt the wax, without turning the burner back on. Technically, beeswax should be heated with a double boiler though). Remove from heat (if you actually had it on heat and weren't a rebel like me). Mix in the strained oil. Add drops of tea tree oil and vitamin E oil. Stir together well and pour into container for storage. Allow to solidify before using.
