Ginger has well-documented anti-inflammatory properties and is known to help reduce inflammation internally. That is why it is often used to alleviate digestion problems. However, the anti-inflammatory properties of ginger can also be used as a topical application. A study published in the Journal of the Medical Association of Thailand showed that a gel containing ginger extract was just as effective as a NSAID gel containing diclofenac.[14] Diclofenac is a popular NSAID used to treat moderate pain. You can also use raw ginger or add a few drops of ginger essential oil to coconut oil and apply to the affected area on your hand.
