Doesn't work for all, I suppose. Well, I used my self made extract (squeezed out oil/juice of flowers on wodka) in '06/'07 over a longer stretch of time and it surely had some positive effects back then. Had some therapy as well in those days but always refused any pharma-drugs. St John's and some other self made herbs extracts (with e.g. valerian) had my preference then. Um, they still do..
