Cupping Therapy & Circulation: Mechanisms & Clinical Effects

Proposed Physiologic Effects

• Hyperemia: Negative pressure dilates capillaries → ↑ local blood flow, O₂ delivery.
• Mechanotransduction: Stretch activates fibroblasts, modulates inflammation.
• Lymphatic facilitation: Interstitial fluid mobilization → reduced edema.
• Neuromodulation: Afferent input may gate pain (gate control theory).

Evidence Snapshot

• Low-quality RCTs show short-term pain relief in low back, neck, knee OA.
• No high-level evidence for systemic “detox” or disease modification.
• Adverse events: burns, petechiae, skin infection, rare compartment syndrome.

Use as adjunct, not substitute, for evidence-based care. Ensure practitioner hygiene and informed consent.
