Echinacea (Echinacea purpurea)
Habitat & Cultivation:
Evening primrose is native to North America and used as indigenous medicine. It can survive most conditions and grows in a creeping manner; blooms in May or June. They have a unique ability to open in the evenings and wither the following day. The seed contains the active ingredient where the EPO is made from. Clinical studies have reviewed its use in treating problems associated with essential fatty acids (EFA) deficiency such as eczema, premenstrual syndrome (PMS), inflammation, and diabetic peripheral neuropathy. EPO contains high EFAs, particularly gamma-linolenic acid (GLA); yielding about 7-10%. Commonly in pregnancy, it is used as a precursor to prostaglandin.
EPO made from the seeds, leaves to treat minor wounds, sore throat and GI issues, and decoction from roots to treat hemorrhoids.
