HOW TO MAKE 507 ACCORDING TO STEINER:
...press the blossoms from the valerian plant and greatly dilute the extract with warm water. The extraction can be done any time and can be stored. If this diluted valerian juice is applied to the manure in a very fine manner, it will stimulate the manure to relate in the right way to the substance we call phosphorus...'
ESOTERIC COMMENT:
Steiner describes the medicinal effect of phosphorus as strengthening the ego potential of a plant and stimulating the phosphate activity in the soil. There is also a Saturn connection.

The stem is erect, angular, furrowed and usually unbranched. Its leaves are odd-pinnate with 7 to 13 ovate to lanceolate, indented-dentate leaflets. The lower ones petiolate and the upper sessile and clasping. It has androgynous, funnel shaped flowers that are pink to white. The fruit is ovate-oblong, achene, and yellow with a white pappus formed from the calyx. The root is harvested in the autumn.
Properties: sedative, mild pain relief, hypnotic, antispasmodic (relieves muscle spasms), carminative (relieves flatulence and associated colic) and has hypotensive properties (reduces blood pressure). Valerian is traditionally used in the treatment of nervous conditions.
