👉 Anti-catarrhal is a term used in medicine to describe a substance that has been shown to have anti-inflammatory properties. It can be found in various medications and may help reduce pain, swelling, and inflammation associated with certain conditions such as rheumatoid arthritis or psoriatic arthritis. The exact mechanism by which it works is not fully understood, but it is thought to involve the production of prostaglandins, which are chemicals produced by the body's immune system that can help alleviate symptoms.
