Registered summary

Osteoarthritis of the knee is a common cause of pain in the US. The currently available medicines for knee osteoarthritis sometimes are not effective at relieving the pain or have unacceptable side effects. Thus, alternate pain relieving treatments are needed. CBD, an active chemical from the hemp derived cannabis sativa plant, has received a lot of attention for its potential pain relieving properties, but there has been limited research to find out if topically applied CBD can decrease pain from knee osteoarthritis. The full summary is on the listing.
