An alcoholic extract of green oats was tried on opium addicts. Six chronic opium addicts gave up opium completely, two reduced their intake and two showed no change following regular use of 2 ml three times daily (human clinical study). A significant diminishment of the number of cigarettes used by habitual tobacco smokers resulted from using 1 ml (four times daily) of

fresh Avena alcoholic extract of mature plants; however, a few studies gave disappointing results. (Francis Brinker.)
