Oatstraw is strongly nutritive and contains calcium, magnesium, silica, Vitamin E, some B vitamins, and beta-carotene. Very restorative on a deep level for depletion. Oatstraw is the foundation of many of my nourishing infusion blends for those with nervous system depletion, endocrine deficiency and general lack of energy and mental clarity. That is why it is in our Adrenal Tonic! For a stronger effect on the nervous system mix with Milk Oat Tops or the tincture.
