Diclofenac Diethylamine and Linseed Oil are key components in topical pain-relief gels, often combined with Methyl Salicylate and Menthol, to treat muscle, joint, and arthritis pain. Diclofenac acts as an anti-inflammatory, while linseed oil boosts skin penetration and reduces inflammation. It provides fast relief for sprains, strains, and bruises.
