My calendula after-bath salve. The camera refuses to capture the deep butter yellow color

On Saturday, as a part of this long series on Calendula (here, here and here), I posted about infusing oil with herbs.

If you’ve got some herb infused oil, you can make that into a medicinal salve or balm. Salve is nothing but oil thickened by the addition of wax. I prefer beeswax salves, though there are vegan alternatives, like candelilla wax. They are used similarly.

Of course, you don’t have to make salves with infused oils. Plain olive oil and beeswax are a powerful healing combination on their own, great for a no-nonsense lip balm or hand treatment. You can also use essential oils to bring herbal essences into a plain salve.

Once you know how to make salve, you can not only make skin salves, you can make lip balm and headache balm and stick deodorant and homemade cosmetics. It’s a simple technique, but it opens a lot of possibilities.

My favorite herbal salve is made out of a mix of equal parts Calendula (pot marigold), chickweed (Stellaria media) and plantain (Plantago major) oils. These three work together to make an all purpose salve that is as good for gardener’s hands as it is for diaper rash or skin scrapes or bug bites or dry cuticles or badly chapped lips or mild sunburn or whatever. I always have a jar on hand and I give jars to friends and family.

Yesterday I made a batch of pure Calendula salve, a big jar of after-bath moisturizer. Like body oil, salve works best as a moisturizer if applied to wet skin. Calendula extracts are found in a lot of high end cosmetics because it’s a mild but effective skin herb. It’s anti-inflammatory, anti-bacterial, soothing, and helps skin regenerate. I love smoothing it from my cat-scratched ankles and my mosquito-bit knees up to my sun-baked face and arms.

How-to after the jump.

The Secret of Salve

The only secret to salve is that it is so darned easy to make.

The only equipment you need is some kind of double boiler situation: a true double boiler, a heat proof bowl balanced over a sauce pan, etc. What I usually do is put a Pyrex liquid measuring cup into a small pan of water. I set the burner on to medium heat and bring the water to a very gentle simmer. Thus the oil heats without overheating or burning.

To the oil I add a little bit of organic beeswax, and continue to heat and stir until the beeswax dissolves. That’s all there is to it, really, but I’ll explain the details.

First, let’s take a moment to talk about beeswax:

Where do you get the beeswax?  You can order it online, just search “organic beeswax”. I wouldn’t buy it in craft or hardware stores unless it’s marked as organic. Beeswax holds on to chemicals, so if the bees were working fields which were sprayed, traces of those chemicals could end up in your balm. Same goes for cannibalizing beeswax candles. I hope to get some nice clean wax from our hive soon, but in the meanwhile I buy my wax from Mountain Rose Herbs. It comes in both pellets and blocks. Pellets are a lot easier to work with.

Good organic beeswax smells heavenly, by the way, and that scent carries into the finished salve.

How much beeswax do you use?  Making salves is all about simple proportions–the ratio of oil to wax. 4 parts oil to 1 part wax yields a firm salve. You’d want this sort of proportion for roll up lip balm tubes or roll up deodorants, cases where firmness is a virtue.

If you don’t necessarily need a firm salve, you have a lot more latitude. 6 parts oil to 1 part wax makes a soft salve, better for scooping up with the fingers.

To tell the truth, even small amounts of wax will firm oil up to a sort of loose ointment consistency. For this Calendula bath salve I just made, I didn’t bother to  measure. I just added a heaping teaspoon of wax to my oil. The ratio must have been 10 or 12 to 1. I wanted something very soft.

So does this make sense? For instance, say I want to fill a particular tin with my skin healing salve. I measure the volume of the tin first, by spooning water into it. Say it holds six tablespoons. The easy math on this one would be to warm 5 tablespoons of oil plus 1 tablespoon of wax (5:1). That would work without resorting to teaspoons and fractions, but if I wanted a looser salve, I might short the wax measure.

Keep in mind it’s very easy to repair a too-hard or too-soft salve. Just reheat it and add more wax or more oil as needed. You can get some sense of how a salve is going to harden up by dropping the hot liquid onto a cold plate–just like jam.

Measuring beeswax: Because salve measurements don’t have to be precise, there’s a few ways to measure out wax. Measuring by the spoonful is easiest–spoonful of oil to spoonful of wax. If you have wax in the pellet form, just measure the pellets by the spoonful. If you have a block of wax, shave the wax and press the gratings into a spoon.

Alternatively, you could measure wax by displacement: pour oils into a measuring cup, then drop in pieces of wax until the liquid level meets the desired measure. For example, for a 6:1 ratio, fill a clear measuring cup to 6 oz. and then add wax chunks until the volume rises to 7 oz.  That equals 6 oz. of oil and 1 oz. wax.

Back to the melting:

Okay, so you’re warming your combined oil and beeswax in a double boiler-type situation, as described above. Once the wax has warmed enough in to dissolve and vanish into the oil, take the oil off the heat.When using herb infused oils, you want to treat them gently and heat them as little as possible.

Add essential oils:

If you want to add any scent, or if you’re into the healing properties of essential oils, this is the time to stir them in–right after you take the mix off the heat, but before you pour it.

For lip balms, I’ll add a few drops of peppermint essential oil. Do be careful with peppermint oil, though–too much will make your lips burn. Think something along the lines of 2 drops of of peppermint essential oil per small tin of lip balm. It’s easy to warm it again and add more if you want it stronger. Same goes for scents. Use a light hand. A few drops will do it in most cases.

Also, I should add that you can infuse oils with scented herbs, like dried lavender buds or rose geranium leaves or chamomile flowers. They’re not as strong as essential oils, but very nice in salves. And a lot cheaper. 

Here’s a hint regarding essential oils: For inspiration regarding what kind of essential oils might go into different types of salves, check out the product line at Badger Balm.

Pour into jars:

Once you’ve stirred in the essential oils, pour the liquid salve into clean, dry jars or tins. Make sure your containers are dry and clean. Dirt or water could lead to contamination and mold.

Pour it fast, before the mix starts to cool. I find that the lip of a liquid measuring cup gives enough control to fill even those fiddly little plastic lip balm tubes.

Let the containers sit, open, until they are completely cool. Then lid them and label them.

Clean up:

The best way I’ve found to deal with the waxy grease residue (since I stopped using paper towels) is to shake a generous amount of baking soda into the dish and then rub it around. The soda lifts and traps the grease. It works like a charm.

Shelf life:

To be honest, I’m not sure what the expiry date is on these things. I’ve never had a salve go bad, but they do lose potency and scent. Also, a salve or lip balm that’s being used is exposed to a lot more bacteria than one which is unopened. I’d say the unopened ones could last 6 months to a year, but once you open a tin or jar and start sticking your fingers in it, you should use it up in a few months.
