Drawing salve is a thick, usually black ointment that people have used for generations on splinters, boils, and other small trouble brewing just under the skin.1The River Reporter. The old drawing salve Despite the name, it doesn’t suck anything out. It changes the skin around the problem so the body can push it out itself.2Legend’s Creek Farm. Drawing Salves On Boils: How Long Does It Take To Work? The name comes from an old belief that an irritating substance could draw evil humors out of the body.3Wikipedia. Salve4Legend’s Creek Farm. Drawing Salves On Boils: How Long Does It Take To Work?
That makes it a helper for small, near-surface problems, not something that removes or cures anything on its own. One product with a similar name, black salve, is a dangerous corrosive and a different thing altogether.5PubMed. A review of topical corrosive black salve
What’s Actually in a Jar of Drawing Salve
The most common drawing salve is ichthammol, sold under the brand name Ichthyol and often just called black ointment.6Wikipedia. Ammonium bituminosulfonate It is made from oil extracted from sulfur-rich shale rock, which is why it is so dark.7Wikipedia. Ammonium bituminosulfonate The shale oil is distilled and treated with sulfuric acid, which turns its sulfur compounds into a form that mixes with water.8PubMed. Rock-to-Pharma: Characterization of Shale Oil-Based Nonbiological Complex Drugs along the Production Process by High-Resolution Mass Spectrometry What’s left is a sulfur-rich ointment that blends with skin oils and soaks into the skin.9Oil Shale. Ichthyol Production from Israeli Shale Oil
Other products share the name. A paste of magnesium sulfate, the same compound as Epsom salt, is also sold as a drawing salve for small boils and splinters.10Wikipedia. Salve It works differently and is lighter in color. Some drawing salves include pine tar, a long-used skin treatment.11PubMed Central. Topical pine tar: History, properties and use as a treatment for common skin conditions
So check the label to see which active ingredient you are buying. Look for ichthammol, or its chemical name, ammonium bituminosulfonate, under active ingredients; the magnesium sulfate kind lists that instead. A percentage tells you how concentrated it is. Herbal “drawing” salves from small sellers sometimes list bloodroot instead, which is a warning sign covered below.
Strength matters. A stronger ichthammol ointment is more likely to sting or dry the skin, so a first-time user is well served by a lower-percentage product if the shelf offers a choice. The inactive ingredients, such as petrolatum or lanolin, make up most of the jar. They decide how greasy and sticky it feels, how easily it spreads, and how well it stays put under a bandage. Lanolin can bother people who are sensitive to it. A jar with no ingredient list is a reason to leave it on the shelf.
How Drawing Salve Works on the Skin
Ichthammol calms inflammation by affecting the chemical signals the body uses to drive swelling and redness.12PubMed. Anti-inflammatory, antibacterial and antimycotic effects of dark sulfonated shale oil (ichthammol) In lab tests it also slows the growth of some bacteria and fungi.13PubMed. Anti-inflammatory, antibacterial and antimycotic effects of dark sulfonated shale oil (ichthammol) Its sulfur compounds are thought to explain much of this healing effect.14Oil Shale. Ichthyol Production from Israeli Shale Oil On top of that, it softens and loosens the skin around a boil, reducing tension so the body can push out pus naturally.15Legend’s Creek Farm. Drawing Salves On Boils: How Long Does It Take To Work? A splinter or pus pocket near the surface may then rise and break through more easily, and that is what looks like “drawing.”
On a small boil, you may notice the skin over it softening and looking wrinkled or pale under the bandage. The boil may come to a head, a visible yellow or white point. It then opens on its own and drains, and pain usually eases quickly afterward.
The black residue on the bandage is usually just the ointment itself, not drawn-out infection. Only pus or a splinter showing at the surface means something actually came out. Judge progress by the size of the spot and how much it hurts, not by what’s on the dressing.
Warm compresses used alongside the salve increase blood flow and help a boil drain.16Legend’s Creek Farm. Drawing Salves On Boils: How Long Does It Take To Work? Many people apply a warm compress to the area for a while before putting on the salve.
To apply it, clean and dry the area first. Spread a thick layer just over the spot, not the surrounding skin. Cover it with a bandage and change it about once a day, rinsing the area between applications.
“It worked” stories can mislead. Many small boils and shallow splinters surface and drain on their own within days, so a salve used during that time can get credit for something the body was already doing. The softening and anti-inflammatory effects are best seen as speeding or easing the process, not as proof of a pulling force.
What It Can and Can’t Help With
Drawing salve has traditionally been used for boils, ingrown toenails, splinters, and small skin cysts.17Wikipedia. Salve Doctors have used ichthammol for over a century for psoriasis, eczema, a scaly rash of oily areas such as the scalp, leg ulcers, and boils, and still consider it useful.18PubMed Central. Ichthammol revisited
Small boils may start draining within 12 to 48 hours.19Legend’s Creek Farm. Drawing Salves On Boils: How Long Does It Take To Work? Larger or deeper boils might take up to a week.20Legend’s Creek Farm. Drawing Salves On Boils: How Long Does It Take To Work? Use that window as a checkpoint: look at the boil’s size and pain level at the start and again after a day or two. Photographing the spot each day with your phone gives an honest comparison, because swelling is easy to misjudge from memory. If it is shrinking, softening, or coming to a head, continuing is reasonable. If it is getting bigger or more painful after two days of use, stop waiting on the salve.
Splinters are a different story. Nothing shows that drawing salve can reliably remove a deep object, so don’t count on an overnight application.21Fairview Pharmacy. Ichthammol Drawing Salve: What to Know Before Using It Dermatologists recommend removing reachable splinters carefully with clean tools.22Fairview Pharmacy. Ichthammol Drawing Salve: What to Know Before Using It
That means washing your hands and the area, and cleaning tweezers or a needle with rubbing alcohol. Pull the splinter out at the same angle it went in. If part breaks off and stays deep, salve can soften the skin but won’t reliably bring it out. Wash and cover the spot afterward.
Depth and material matter. A splinter just under the surface, with one end visible or easy to feel, is the kind most likely to work its way out as the skin softens. Wood and plant splinters tend to cause more inflammation than smooth material because they carry bits of organic matter, so leaving one in is less wise. A splinter you cannot see or feel, or one that has gone in deeply, is not a candidate for waiting on salve.
For an ingrown toenail, salve can calm a red, sore nail edge. It does not change how the nail grows, so the problem often returns. Soaking and wearing roomy shoes matter as much as the ointment.
Side Effects, Smell, and Stains
The usual effects are mild stinging, redness, or itching, softening or wrinkling of skin under the dressing, and a temporary brown stain.23Bayview Pharmacy. Ichthammol Ointment, Drawing Salve Irritation is more likely on sensitive or broken skin.24Synapse Patsnap. What are the side effects of Ichthammol? Normal irritation stays where you applied the salve and fades within hours.
Ichthammol can cause an allergic skin rash in some people, though this is uncommon.25Bayview Pharmacy. Ichthammol Ointment, Drawing Salve Allergy tends to worsen with each application and spread past the edges of the spot. If the rash gets redder, itchier, blistered, or spreads beyond where you put the ointment, stop and see a doctor or pharmacist.26Bayview Pharmacy. Ichthammol Ointment, Drawing Salve
A small test patch helps. Dab a little on unbroken skin, such as the inner forearm, and wait a day to see if redness, itching, or swelling develops. This is most worth doing if you have reacted to skin products before or have eczema, since that skin tends to be more reactive. A clean result is not a guarantee, but it catches many reactions before the salve goes on tender skin.
Keep it away from eyes, lips, and the inside of the nose. Be careful on the face, genitals, and skin folds, where irritation is more likely. Don’t pack it into open, deep wounds.
Ichthammol has a very strong, distinctive smell that some people find unpleasant, though it isn’t harmful.27Synapse. What are the side effects of Ichthammol? Its dark color can stain clothing, bedding, and skin.28Synapse. What are the side effects of Ichthammol? Cover it well and use old sheets or socks.
Skin stains fade in days with soap and warm water. Treat fabric quickly with detergent before it sets.
Drawing Salve Is Not Black Salve
Black salve can be made corrosive by adding bloodroot or zinc chloride.29PubMed. A review of topical corrosive black salve It is sold as an alternative skin cancer treatment.30Journal of Herbal Medicine. Black salve composition: An evaluation of the potential for normal tissue toxicity and treatment failure from black salve products Most products tested had bloodroot’s active compound at levels that kill normal skin cells, one at 900 times that level.31Journal of Herbal Medicine. Black salve composition: An evaluation of the potential for normal tissue toxicity and treatment failure from black salve products Most also contained zinc chloride at strengths known to kill normal tissue.32Journal of Herbal Medicine. Black salve composition: An evaluation of the potential for normal tissue toxicity and treatment failure from black salve products
Corrosive black salve destroys healthy tissue even on harmless growths, so it doesn’t target cancer.33PubMed Central. Persisting Cancer in Black Salve Treated Skin Lesions: Results of a Large 5 Year Retrospective Analysis of Australian Histopathology Specimens It can leave cancer behind while scarring the surrounding skin badly.34PubMed. Histopathologic findings and diagnostic difficulties posed with use of escharotic agents for treatment of skin lesions: a case report and review of the literature Treated skin can show deep scarring, ulceration, and dead tissue.35PubMed. Histopathological features associated with application of black salve to cutaneous lesions: a series of 16 cases and review of the literature Australia’s medicines regulator warns people not to buy or use black or red salves for cancer, citing no credible evidence they work.36Therapeutic Goods Administration. Black and red salves in treating cancer
In the store, ichthammol drawing salve lists ichthammol or ammonium bituminosulfonate as its ingredient. Black salve often lists bloodroot, also called Sanguinaria canadensis, or zinc chloride. Any product promising to remove moles, tumors, or skin cancer is not a drawing salve. Online herbal sellers are where the dangerous version usually appears.
A natural origin doesn’t make it safe. Bloodroot is a plant, but its active compound works by killing cells, and it does not separate cancerous cells from healthy ones. Zinc chloride is a caustic chemical used in industry, and on skin it burns tissue however the product is marketed. “Natural” and “herbal” on a label say nothing about safety. Testimonials usually show a scab or scar dropping off, but without a biopsy nobody knows whether the growth was cancer at all, or whether any was left behind.
If you’ve already put it on a growth, stop using it right away and see a doctor, since cancer may remain under the scar. Tell them what you used, because it changes how the skin looks under the microscope.
When to Skip the Salve and See a Doctor
The standard treatment for a skin abscess is incision and drainage, where a clinician cuts it open and lets the pus out.37PubMed Central. The Treatment of Cutaneous Abscesses: Comparison of Emergency Medicine Providers’ Practice Patterns The clinician removes any foreign object, rinses the cavity, and leaves it open to drain.38DermNet. Cutaneous abscess Antibiotics are sometimes added, chosen to match the germ causing it.39DermNet. Cutaneous abscess
At the clinic, the area is numbed with a small injection. A short cut lets the pus out, and the inside is rinsed. A deep abscess may get a wick of gauze to keep it draining. Most people go home the same day with dressing instructions.
Antibiotics alone often don’t solve an abscess. Pus collects in a pocket that the bloodstream carries medicine into poorly, so drainage does most of the work. Antibiotics are added mainly when there is spreading redness, fever, or other risk factors, not as a replacement for having it drained.
Squeezing at home is a bad idea. It can push infection deeper into the skin and spread bacteria to nearby skin. Warm compresses and patience are safer while you decide.
Get medical care if redness spreads, red streaks appear, or you develop a fever or chills. See a doctor for a boil larger than about 1 cm, one that is very painful, or one on the face, spine, or groin. People with diabetes or a weak immune system should have boils checked early. Deep splinters, glass, metal, or anything near the eye need professional removal.
A boil that has drained can still need care. If it opens but keeps refilling or stays painful, a pocket may not have emptied fully, and a clinician should look at it. Repeated boils in the same area are worth mentioning to a doctor, since they can point to a germ living on the skin that needs a different approach.
