Avena Sativa, Oat Ellingwood, who has much confidence in avena, says of it: "Its selective influence is directly upon the brain and upon the nutritive functions of the organism, increasing nerve force and improving the nutrition of the entire system." It is indicated in neurasthenia, occipital headache, where phosphates are deficient in the tissues, in the prostration of brain workers, sexual neurasthenia, local and temporary paralyses, menstrual headaches, and in the treatment of victims of the morphine habit. Dose: Ec. tr. or any concentrated tincture, I5 I, well diluted, 3 or 4 times a day. It acts in harmony with strychnia when a stimulant is needed. Exalgin and avena in combination have been used in chorea. Avena is not suitable for administration in small doses.
