Salve vs. Balm vs. Ointment vs. Butter: What's the Difference?

August 5, 2026

Salve, balm, ointment, butter: four words that show up on tins and jars that look nearly identical. They’re close cousins, and the differences are real but small: what the base is, how much wax is in it, and how firm the finished product sets.

One thing all four share: none of them contain water, which is why none of them need a preservative to sit safely on a shelf. There’s a name for that kind of formula, anhydrous.

	Base	Texture	You’d reach for it when
Salve	Herb-infused oil + beeswax	Soft, spreadable	You want herbs delivered to skin
Balm	Oil or butter + more wax	Firm, holds its shape	It lives in a pocket or purse
Ointment	Often petroleum jelly	Semi-solid, glossy	A pharmacy product, usually medicated
Body butter	Whipped plant butters	Rich, creamy	Large areas of dry skin

What is a salve?

A salve starts with an herb-infused oil and gets thickened with beeswax, usually at about 1 part wax to 4 parts oil. The wax does two jobs: it turns liquid oil into something you can scoop from a tin, and it holds the oil against your skin so the plant compounds stay where you put them. Everything in our salve collection sits in this column.

What makes a balm different?

The difference is mostly wax. A balm is built to hold its shape at body temperature, which is why a lip balm survives a summer pocket while a salve would go soupy. The extra firmness comes at a small cost: it spreads less easily over a large area. In practice the two words overlap constantly, and plenty of makers use them interchangeably for the same texture.

Where ointments fit

Ointment is mostly a pharmacy word. Commercial ointments are usually built on petroleum jelly or mineral oil and carry a medicated ingredient, the way an antibiotic ointment does. The texture is glossier and greasier than a beeswax salve. Nothing about the word requires petroleum, though. An old herbal recipe that says “ointment” usually means what we’d now call a salve.

Body butters

A body butter skips the wax entirely and gets its thickness from plant butters like shea or cocoa, often whipped to make them spread easily. They’re the richest of the four and shine on large areas: legs after a shower, elbows and heels in winter.

How they all work on skin

Every one of these puts a layer of oil on top of the skin, and that layer physically slows water from evaporating out of it. A layer that works that way is called an occlusive. The herbal versions add a second job on top: the infused oil carries the plant’s compounds, so the base is also the delivery method.

If it’s the herbal column you’re after, our salves are made in small batches, and Muscle Rub is a good place to see how a working salve is put together: cayenne infused into the oil, beeswax holding it against the skin.

A note on safety

Patch test anything new, and keep salves and balms away from the eyes and broken skin unless a product is made for that purpose. This article is educational; it is not medical advice.
