Comfrey root has a long history of traditional use to heal wounds and fractures when applied as a poultice, and was commonly known as ‘knit bone’. Modern research shows that comfrey contains two main active ingredients: allantoin which promotes tissue regeneration, and rosmarinic acid which damps down inflammation and reduces pain. Comfrey root cream is a popular and effective treatment for joint pain, sprains and strains.
The only side effect most of these products have is odor. Some of them were reviewed as being neutral to actually smelling good, while others were reported to have quite a strong smell you might not like. A lot of this has to do with the nature of the ingredients in pain relieving treatments. Mentholated ingredients give natural relief, but they do tend to have a strong odor that accompanies them.
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.
