Authors of a 2016 review published in Seminars in Arthritis & Rheumatism conclude, “Topical NSAIDs have a moderate effect on pain relief, with efficacy similar to that of oral NSAIDs, with the advantage of a better risk:benefit ratio.” However, A 2016 Cochrane review looked at 39 studies with 10,631 participants and found that topical diclofenac, “can provide good levels of pain relief in osteoarthritis, but only for about 10% more people than get this result with topical placebo.”
While there are mixed answers on how many servings of leafy greens one should eat each day for preventive effects, an overall eight to ten servings of vegetables and fruits daily is recommended for the best results.

I’m not saying NSAIDs are useless. They have their place. If you’re recovering from surgery or a major injury, traditional over-the-counter pain relievers are good for controlling inflammation, swelling, and pain, but NSAIDs are far too powerful for over-the-counter, everyday use. Unlike a lot of natural pain relievers, NSAIDs also don’t address the cause of inflammation or pain; they just mask the symptoms.
