You’re staring at it in the mirror. That stubborn, painful lump under your skin that feels like a marble. It’s a cyst. Your first instinct is probably to squeeze it, but your second is likely a frantic Google search that leads you to an old-school remedy: drawing salve for cysts.
Maybe your grandmother called it "black ointment." Or perhaps you’ve seen the tiny orange tins of Ichthammol at the back of a pharmacy shelf, looking like a relic from the 1940s. It smells like asphalt and looks even worse. But does it actually do anything for a sebaceous cyst or a painful boil? Honestly, the answer is a bit more complicated than "yes" or "no." It’s about managing expectations and knowing exactly what’s happening under your epidermis.
The Chemistry of "Drawing Out" a Cyst
What is this stuff, anyway? Most traditional drawing salves rely on a heavy-hitter ingredient called Ichthammol (ammonium bituminosulfonate). It’s derived from sulfonated shale oil. Essentially, it’s a byproduct of distilled rocks. Sounds appetizing, right?
When you slather drawing salve for cysts onto your skin, it performs two main tricks. First, it softens the keratin—the tough protein that often plugs up a pore or hair follicle to create a cyst in the first place. By softening that "cap," the pressure inside has a better chance of pushing through. Second, it’s a mild irritant that increases blood flow to the area. This localized inflammation is actually a signal to your body to send more white blood cells to the site.
It doesn't literally "suck" the cyst out like a vacuum. That’s a myth. Instead, it encourages the cyst to "come to a head" or drain on its own by weakening the skin barrier and increasing internal pressure.
Why the Smell Matters
If you’ve ever opened a tin of Prid or a generic 20% Ichthammol ointment, you know that pungent, campfire-meets-paving-tar scent. That’s the sulfur. Sulfur is naturally antimicrobial. While it won't cure a deep-seated genetic cyst, it helps keep the surface bacteria (like Staphylococcus aureus) from turning a simple clogged pore into a full-blown, fever-inducing infection.

Cysts vs. Boils: A Crucial Distinction
People use these terms interchangeably. They shouldn't.
A boil (furuncle) is an infection of a hair follicle. It’s full of pus and bacteria. Drawing salves are actually pretty great for boils because they help the body localize the infection and drain it.
A true sebaceous cyst or pilar cyst, however, is a different beast. These are essentially small sacs lined with skin cells. They are filled with macerated keratin—which looks like cheesy, white gunk—and they have a "sac wall."
Here is the hard truth: Drawing salve for cysts will not remove the sac. You might get it to drain. The swelling might go down. You might feel 100% better for a month. But if that sac wall remains under your skin, the cyst will almost certainly refill. It’s like emptying a water balloon without taking the balloon out of the bucket. Eventually, it’s going to fill up again. Dermatologists like Dr. Sandra Lee (the famous Dr. Pimple Popper) frequently point out that surgical excision is the only permanent "cure" for a recurring cyst.
How to Actually Use Drawing Salve Without Making Things Worse
If you’ve decided to try the DIY route, don’t just glob it on and go. You’ll ruin your bedsheets and potentially irritate your skin.
- Clean the area first. Use mild soap and warm water. Don’t scrub.
- Apply a thick layer. You want a visible "mound" of the ointment over the center of the lump.
- Cover it tightly. This is non-negotiable. Ichthammol stains everything it touches—clothes, upholstery, your soul. Use a large adhesive bandage or gauze taped down on all four sides.
- Wait 24 hours. Give it time to work.
- Heat is your friend. Placing a warm (not scalding) compress over the bandage for 10 minutes, three times a day, can speed up the process by further increasing blood flow.
Sometimes, after a day or two, you’ll see a small white or yellow point appear. This is "coming to a head." If it opens on its own, let it drain naturally. Whatever you do, do not perform "bathroom surgery." Digging into a cyst with a needle you "sterilized" with a lighter is a one-way ticket to cellulitis.
When to Walk Away (The Danger Signs)
I’ve seen people try to use drawing salve for cysts on things that definitely weren't cysts. This is where it gets dangerous.
If your "cyst" has red streaks radiating away from it, stop. If you have a fever or chills, stop. If the area is hot to the touch and the redness is spreading rapidly, you aren't dealing with a simple clogged pore—you might be looking at a staph infection or MRSA.
Also, never use these salves on your face without a "spot test" first. The skin on your cheeks and forehead is much thinner than the skin on your back or thighs. The irritating nature of Ichthammol can cause a secondary contact dermatitis, leaving you with a red, itchy rash on top of your existing cyst. Not a good look.
The Modern Alternatives
While Ichthammol is the "OG," there are other options now.
- Hydrocolloid Bandages: These are those "pimple patches" you see everywhere. They work on a similar principle of moisture retentions and drawing out fluid, but they are much cleaner and less irritating.
- Magnesium Sulfate Paste: Another old-school drawing agent that uses osmotic pressure to pull fluid toward the surface.
- Warm Compresses Alone: Honestly? Most dermatologists will tell you that a warm washcloth applied for 15 minutes, four times a day, does about 80% of what a drawing salve does, minus the smell.
The Verdict on Drawing Salve
Is it a miracle cure? No. Is it a useful tool in your first aid kit? Absolutely.
Drawing salves are best used for symptomatic relief. They reduce the pressure. They help the skin "thin out" so a cyst can drain. They provide a bit of numbing relief (Ichthammol has slight analgesic properties). But they are a temporary fix.

If you have a cyst that keeps coming back in the same spot, or one that is located in a sensitive area like your armpit or groin (which could be Hidradenitis Suppurativa), the salve is just a Band-Aid. You need a professional to numb the area, make a clean incision, and remove that sac wall entirely.
Practical Next Steps for Your Skin
If you are currently dealing with a painful lump, follow these steps:
- Assess the "Head": If there is no visible opening or "point," apply a 20% Ichthammol drawing salve and cover it for 12-24 hours.
- The Warmth Rule: Use a warm compress even if you use the salve. The heat assists the chemical action of the ointment.
- Hands Off: Resist the urge to squeeze. Squeezing a deep cyst can rupture the sac downward into your bloodstream or deeper tissue, causing a much more severe infection.
- Monitor for 48 Hours: If there is no change or the pain increases after two days of using a drawing salve, it’s time to call a primary care doctor or a dermatologist.
- Document the Recurrence: If this is the third time a lump has appeared in this exact spot, skip the pharmacy aisle. You need a surgical excision to prevent a lifetime of using salves on a recurring problem.
