White willow bark, for instance, may have pain-relieving properties similar to aspirin. Salicin, a compound found in white willow bark, is converted in the body to salicylic acid, just as aspirin is. Salicylic acid is believed to be the active compound that relieves pain and inflammation. Another herb sometimes used in the treatment of back pain is devil's claw. Devil's claw contains harpagosides, which are chemical compounds found to possess anti-inflammatory properties.

Traditional wisdom says that NSAID pain relievers only damage your gut lining if you take them every day for a long time, but recent research disagrees. High-level athletes with stress-related intestinal damage tried taking ibuprofen to improve muscle soreness and recovery. Ibuprofen ended up damaging their gut lining even further after just a couple weeks; it increased inflammation and made their original pain issues worse. In fact, a single dose of aspirin can significantly increase your intestinal permeability.
