Evening Primrose Oil
Evening primrose oil comes from the evening primrose plant that is native to North America. The oil is a good source of the essential fatty acid called gamma-linolenic acid, an acid used for many therapeutic treatments.
Evening primrose oil helps relieve symptoms of rheumatoid arthritis because of its ability to suppress inflammatory responses. Plus, it can be taken as a dietary supplement. The other parts of the plant can also be eaten as normal green vegetables or made into a tea for brewing.
