Capsicum plaster, a type of topical analgesic patch, utilizes capsaicin—the active compound in chili peppers—to provide localized pain relief. This traditional yet scientifically backed treatment is widely used for musculoskeletal pain, arthritis, and neuropathic conditions.
The primary mechanism of capsicum plaster involves capsaicin’s interaction with sensory neurons. It binds to TRPV1 receptors, initially stimulating a burning sensation before desensitizing nerve endings by depleting substance P, a neurotransmitter responsible for pain signaling. Over time, this reduces chronic pain perception.
Clinically, capsicum plaster is effective for:
Osteoarthritis & Rheumatoid Arthritis: Studies show improved pain scores in knee and hand arthritis.
Neuropathic Pain: Helps manage diabetic neuropathy and postherpetic neuralgia.
Muscle Strains & Back Pain: Provides temporary relief by increasing blood flow and reducing stiffness.
Application involves placing the plaster on clean, dry skin for 4–12 hours, depending on formulation. Mild redness or warmth is common, but excessive irritation may require discontinuation. Contraindications include broken skin and hypersensitivity to capsaicin.
Compared to oral painkillers, capsicum plaster minimizes systemic side effects, making it a safer long-term option. However, patients should consult a physician before use, especially if taking blood thinners or anti-inflammatory drugs.
In summary, capsicum plaster offers a non-invasive, drug-free alternative for chronic pain management with a well-established efficacy profile.
