5. Comfrey Extract
Another natural treatment you can try is comfrey root cream. A recent study on people with back pain shows that it can significantly reduce suffering when applied topically. Almost 95% of participants reported that they felt better after using it. Further studies in people with arthritis and with ankle sprains had consistent findings.
Science’s best guess as to why comfrey works to relieve pain is the allantoin and rosmarinic acid content. Researchers have determined that rosmarinic acid reduces inflammation and soothes pain, but allantoin can help by speeding up the growth of new skin cells. Comfrey is to be used externally only; there is some concern that it may be carcinogenic when eaten, but more studies are necessary.
