Echinacea angustifolia is, in many ways identical to Echinacea purpurea , and despite the assumption among Health Professionals that the active ingredients are of a higher concentration, we have noted identical values of PS I (35 kilodalton) and PS II (450 kilodalton) in both species.
I would hazard a guess that the quality of the extract has more to do with the quality of the soil and the growing rather than the variety of the plant.
E.angustifolia is slower and more erratic in germination and must have friable soil. It tends not to respond well to a lot of fertilization, so it's best to leave them alone to get on with the job.
Water and mulch well but take care not to disturb the roots too much.
Plant in full sun to partial shade.
Not only is it a pleasure to grow, its uses are limitless. We use the roots of Echinacea to stimulate the immune system and promote healing.
Echinacea's most common use is to ward off the onset of the common cold and to alleviate the effects of a sore throat. Parts Used: Roots (Dried) and fresh leaves of a two year old plant.
It must be noted that most of the ínformation' that was collected last century and published almost endlessly, copied and pasted everywhere imaginable regarding the qualities of Echnicea as an herb and quote specifically E.angustifolia over E.purpurea were done in Germany and have recently been abandoned, as it was discovered that all of the samples used for the analysis were corrupted. E.angustifolia was chosen because it was availble cheaply and not because it was more effective.
