Drawing salve is a popular folk remedy often found in traditional first-aid kits. These ointments promise to naturally “draw out” impurities, foreign objects, or infections from beneath the skin, appealing for issues like splinters and boils. When considering its use for a cyst, it is important to examine the scientific understanding of the product and the biological structure of the condition. This article explores the claims made about drawing salves and compares them against current medical knowledge and approved treatment options.
Understanding Drawing Salves and Traditional Claims
A drawing salve is a topical ointment traditionally used to promote the expulsion of material from the skin. The most common form is Ichthammol ointment, often called black salve, which contains Ammonium Bituminosulfonate, a sulfurous compound derived from shale oil. This compound has mild antiseptic and anti-inflammatory properties. While traditionally believed to create suction, the actual mechanism involves creating a moist, warm environment. This softens the outer skin layers, encouraging trapped fluid, such as pus from a boil or abscess, to move toward the surface and drain. Other components, like bentonite clay or activated charcoal, are sometimes included for their absorbent properties.
The Biological Structure of Cysts
A cyst is a closed, sac-like structure that forms beneath the skin, distinct from a simple pimple or boil. This sac is lined with a wall of epithelial cells that continuously shed and accumulate contents inside the capsule. Epidermoid cysts, the most common type, are filled with keratin, a thick, cheese-like substance made of dead skin cells. This distinct, encapsulated sac is the defining feature of a true cyst. Unlike a boil, which resolves when pus drains, a cyst requires the removal of the entire lining or wall to prevent recurrence.
Scientific Assessment of Salve Effectiveness
There is no scientific evidence that a drawing salve can dissolve the epithelial wall of a cyst or “draw out” the entire sac. The salve’s mechanism, which encourages superficial drainage by softening the skin, is effective for surface infections or foreign bodies. However, a true cyst is a deep, encapsulated structure that does not respond to topical surface treatments. If a cyst is inflamed or infected, the salve may encourage a small amount of pus or fluid to drain, offering temporary relief. This drainage addresses only the infection, not the permanent cyst wall, meaning the cyst will likely return. Furthermore, the U.S. Food and Drug Administration (FDA) has not approved drawing salves for treating cysts. Some corrosive products marketed as black salve are actively discouraged due to severe tissue damage risks.
Risks and Medically Approved Treatment Options
Using drawing salves on deep cysts carries several risks that can complicate the condition. Applying an irritant to a deep, closed lesion can increase inflammation and swelling, potentially leading to a secondary bacterial infection. Corrosive products marketed as drawing salves, such as those containing zinc chloride or Sanguinarine, can cause severe chemical burns, tissue necrosis, and permanent scarring. Relying on a folk remedy also delays seeking necessary medical care, allowing the cyst to become larger, more painful, or severely infected.
Medically approved treatments focus on complete resolution and preventing recurrence. For inflamed cysts, a healthcare professional may perform a steroid injection to reduce swelling and pain. To definitively treat a cyst, a medical provider must remove the epithelial sac. Minor surgical procedures, such as complete surgical excision or minimally invasive punch biopsy techniques, ensure the cyst wall is entirely removed. Individuals with a growing, painful, or infected lump should seek professional medical evaluation for an accurate diagnosis and appropriate, safe treatment.
