I take Starflower oil rather than Evening Primrose oil.
Both oils are very rich sources of GLA, Gamma Linolenic Acid.
The only difference between the two is that starflower contains twice the amount of concentration. In fact, starflower is the highest natural plant based source of GLA.
Evening Primrose is native to the USA and Starflower is Borage which is a European plant. It has pretty blue star shaped flowers and is commonish in the Mediterranean.
I suffer with very sore, tender, lumpy hormonal breasts, with the inflammation radiating out to my armpits.
It was in fact my breast doctor who told me to take the Starflower oil. You must take it every day and after a few weeks my boobs definitely felt better.
Anyway, I have continued with it and it is the basis of my trusted cocktail of supplements (the others I am still experimenting with!).
There is lots research to show that GLA helps with joint problems, rheumatoid arthritis.
If you love Evening Primrose, stick with it but just thought you might like the Starflower thoughts xx
