The Healing Power in a Little Seed

Evening Primrose oil
is produced from pressed small seeds of the Oenothera biennis plant.
Evening primrose oil can be taken in supplement form as a rich source
of essential fatty acids (EFA's). Evening primrose oil contains
Omega-6 EFA's. Omega-3 EFA's should be taken too when supplements
such as Evening Primrose oil rich in Omega-6's are taken. Fish or
fish oil supplements are often recommended by health practitioners as
the best source of Omega -3 EFA's. Examples from studies on evening
primrose that have shown beneficial to humans are included below:
BREAST PAIN:
Evening primrose oil given orally, 6 capsules per day for three to six
months (dosage not reported), significantly reduced severe and
persistent mastalgia (breast pain) in 45% of participants with cyclical
mastalgia and in 27% of patients with noncyclical mastalgia.
Ninety-five percent of those who responded to evening primrose oil did
so within three months and 2% of the patients in both groups complained
of a bloated feeling with nausea after taking the evening primrose oil
(Pye, Mansel, & Hughes, 1985).
POST VIRAL FATIGUE SYNDROME:
After three months of daily treatment with 4000 mg evening primrose oil
(Epogam) and fish oil, 85% of patients in the treatment group diagnosed
with postviral fatigue syndrome demonstrated significant improvement as
compared with the placebo group in a double-blind, placebo-controlled
trial of 63 adults (Behan, Behan, & Horrobin, 1990).
DEPRESSION AND SCHIZOPHRENIA:
Evening primrose oil, an omega-6 EFA, contains high amounts of gamma
linolenic acid (GLA). The GLA content of evening primrose oil is of
interest because it is a precursor of prostaglandins, especially PGE1.
Prostaglandins help regulate many metabolic functions. PGE1 is
important in nerve cell transmission and is both anti-inflammatory and
immunostimulating. Affecting the PGE1 pathway has been shown to improve
conditions such as depression and schizophrenia, multiple sclerosis,
PMS, and attention deficit hyperactivity disorder (Schmidt, 1997).
