Yes, Patchouli essential oil is great for treating eczema or just control it. I mix Patchouli essential oil (1 drop x 6 ml of fragrance free organic cream + 10 ml of Argan oil) or l dilute 4 drops of Patchouli in 5 ml of alcohol and add it just before having a bath...

Got eczema when l was pregnant with my first child... many years ago... was really severe... but everything changed with time... now l almost don't have it... it is fully controlled... it is getting a little bit worse during cold period of time of the year but the methods mentioned above help me to control it and not to expand.
