Inflammation and Pain
Methylene blue (MB) exhibits exceptional anti-inflammatory properties by effectively targeting cytokines released during the immune response. By blocking their signaling pathways (including IL-6 and TNF-α), it helps mitigate inflammatory processes within the body.
Protective Effects on Joints and Cartilage:
Studies using osteoarthritis models have demonstrated that MB protects cartilage from damage and concurrently reduces pain. These effects indicate its potential therapeutic utility in the treatment of degenerative joint diseases.
Protection of Immune Cells:
MB prevents lymphocyte (T-cell) death by suppressing caspase-1 and -3, thereby limiting both pyroptosis and apoptosis. This mechanism may protect tissues from damage caused by infection or chronic inflammation.
Efficacy Against Severe Conditions:
In vivo research confirms that methylene blue significantly suppresses TNF production and prevents complications in endotoxic shock. Furthermore, it protects the liver by mitigating oxidative stress and the inflammatory response.
Targeting Inflammatory Complexes – Inflammasomes:
Inflammasomes are protein complexes that trigger inflammatory responses and cell death. MB effectively suppresses their activation, suggesting considerable potential for treating diseases associated with hyperactivity of these mechanisms (e.g., autoimmune disorders).
A Novel Approach in Pain Therapy:
Recent studies indicate that MB may be more effective than traditional local anesthetics (e.g., lidocaine). Animal experiments have shown that it provides long-term reduction in pain-associated neural activity, thereby offering relief for a significantly extended duration.

Promising Results in Other Areas:
Studies on rats with induced disease suggest that MB may have broader therapeutic applications, which are the subject of ongoing research.
