| š” Quick Answer |
| A drawing salve is a traditional topical ointment commonly containing ingredients like Ichthammol, activated charcoal, or bentonite clay. It is traditionally used to “draw out” splinters, toxins, or pus from minor irritations like boils and simple insect bites. Drawing salve is NOT a medically proven treatment for venomous spider bites (like the Brown Recluse) or for skin infections. CAUTION: Salves containing corrosive ingredients like Sanguinarine (bloodroot) or Zinc Chloride (often called “Black Salve”) are highly dangerous and can cause permanent tissue destruction and scarring. Use only FDA-compliant products for minor, non-venomous bites. |
What Is Drawing Salve and How Does It Work?
Drawing salve is a generic term for an ointment used in folk and traditional medicine. It is typically a thick, dark paste applied to the skin and covered with a bandage.

Common Ingredients
While recipes vary widely (and modern products differ significantly from corrosive traditional ones), most non-harmful drawing salves contain one or more “drawing” agents:
- Ichthammol (or Ichthyol): A common component in commercial “drawing salves.” It is a dark, sticky substance known for its mild antiseptic and anti-inflammatory properties, and is traditionally used for boils and minor skin irritations.
- Activated Charcoal: Known for its highly porous structure, which allows it to bind to impurities and toxins on the skinās surface.
- Bentonite Clay: A natural clay with absorbent properties that traditionally helps to detoxify and soothe irritated skin.
- Herbal Extracts: Ingredients like plantain, calendula, or arnica are often included for their purported soothing and healing benefits.
Traditional Use for Bites
The principle behind using drawing salve for a bite is the belief that the “drawing” agents help to pull out toxins (venom) or irritants left behind by the insect, thereby speeding up the healing process and preventing the formation of pus or boils. This claim is largely anecdotal and lacks strong scientific backing, especially regarding spider venom.
Safety Warning: The Danger of “Black Salve”
A critical distinction must be made between mild, Ichthammol-based drawing salves and highly dangerous corrosive products often sold as “Black Salve” or “Escharotic Salves.”
| Product | Common Ingredients | Health Danger |
| Traditional/Ichthammol Salve | Ichthammol, Activated Charcoal, Clay, Herbs, Beeswax | Generally safe for minor irritation, but ineffective against venom. |
| Corrosive “Black Salve” | Sanguinarine (Bloodroot), Zinc Chloride | EXTREME DANGER. These ingredients chemically destroy skin tissue (necrosis) and can lead to permanent disfigurement, deep scarring, and severe infection. They are not FDA-approved for any skin condition. |
The U.S. Food and Drug Administration (FDA) strongly warns consumers against using Black Salve products containing corrosive ingredients, as they destroy both healthy and damaged tissue. They can also mask or delay diagnosis of serious conditions, including skin cancer or severe spider bite necrosis.
When to Use and When to Avoid Drawing Salve
Given the lack of scientific evidence for treating venom and the risks associated with certain ingredients, strict caution is necessary.
Use ONLY For (Mild, Simple Bites):
A non-corrosive, Ichthammol-based salve may be used as a comfort measure for simple, non-venomous insect bites (like mosquitoes or gnats) that have developed minor irritation or a small, non-spreading bump, similar to a soothing balm.
AVOID ENTIRELY For (Medical Emergencies):
NEVER use drawing salveāespecially the black/corrosive typeāon the following conditions:
- Suspected Venomous Bite: If you suspect a bite from a Brown Recluse or Black Widow spider. These require immediate professional medical management, not traditional salves.
- Infection: If the bite shows signs of spreading infection (fever, red streaks, pus). Salves do not replace prescription antibiotics.
- Deep Wound/Ulcer: If the bite is open, blistering, or showing signs of necrosis (dark, sunken tissue). Applying a salve to dead tissue is ineffective and can hinder necessary medical treatment.
First Aid: Focus on Proven Methods
For all spider bites, whether mild or severe, focus on proven medical first aid:
- Clean the Area: Wash with soap and water.
- Apply Cold: Use a cold compress to reduce swelling and slow inflammation.
- Seek Medical Care: Call your healthcare provider immediately if the bite looks infected, or if you experience systemic symptoms (fever, body aches, muscle cramps). [Source Citation: Link to Mayo Clinic on Spider Bite First Aid]
Frequently Asked Questions (FAQ)
Is Ichthammol Drawing Salve safe for my skin?
Ichthammol (sometimes called Ichthyol) is generally recognized as safe for external use and is available over-the-counter for minor skin irritations. However, its effectiveness against spider venom is unproven, and it should only be used for the most minor, non-venomous bites.
Can drawing salve draw out the venom from a Brown Recluse bite?
No. Brown recluse venom (loxoscelism) causes cellular destruction (necrosis) deep within the skin. A topical salve cannot reach or neutralize the venom that has already been injected and begun its damage. Time is critical for a venomous bite, and medical intervention is necessary.
Why do some people swear by drawing salves?
Drawing salves have been used for centuries, giving them a strong cultural reputation. They are effective at softening the skin and helping to expel superficial, solid objects (like splinters) or trapped pus from small boils, leading users to believe they are working on venom or other deep toxins. For minor irritations, they often provide comfort, which is easily mistaken for a cure.
Final Thoughts
Using drawing salve for spider bites can be an effective way to relieve discomfort, reduce swelling, and speed up recovery. However, it should complement ā not replace ā professional medical care. Always monitor symptoms closely, and if you notice severe pain, spreading infection, or necrosis, seek immediate help from a healthcare provider.
By combining medical-grade care, proper hygiene, and expert-reviewed treatments, you can ensure safe and effective healing from spider bites.
