Common Name : Oats. 

Preparation : The fresh green plant, gathered in August, is pounded to a pulp and macerated with two parts by weight of alcohol. 

(Comparatively little has been written concerning this remedy, the tincture of oats. 

It acquired a bad reputation somewhere in the "eighties" by being advertised as a proprietary remedy making wonderful cures, but analysis showed the advertised "Avena" to contain opium. 

The following outline of the drug is by Dr. E. H. Russell, in North American Journal of Homoeopathy) 

Avena sativa is pre-eminently an anti-neurotic, quieting the nervous system to a remarkable degree. 

Its special sphere of action seems to be upon the male sexual organs, regulating the functional irregularities of these parts perhaps as much as any drug can. 

It is a most useful remedy in all cases of nervous exhaustion, general debility, nervous palpitation of the heart, insomnia, inability to keep the mind fixed upon any one subject, etc., more especially when, any or all of these troubles is apparently due to nocturnal emissions, masturbation, over sexual intercourse, and the like. 

For these disorders it is truly specific. 

It is one of the most valuable means for overcoming the bad effects of the morphine habit. 

In most cases in which the habitue has not used more than four grains daily the Opiate may be abruptly discontinued, and even substituted, without any serious results. 

If a larger quantity than this amount has-been taken for some time, it is better to gradually reduce the daily dose of morphine, in the usual manner, simply prescribing the Avena in addition. 

The latter should be given in the same dose, as a rule, regardless of the amount of morphine taken. In other words, it is not necessary to increase the Avena as the opiate is withdrawn. 

When the quantity of morphine has not exceeded four grains daily it should be stopped at once, as stated above, and Avena given in its stead in fifteen drop doses, four times a day, in a wineglassful of hot water. 

By this method the disagreeable after-effects will be much less than though the dose of morphine is gradually reduced, and the patient will find life quite bearable, as a rule, at the end of a week. 

Avena sativas hould always be given in appreciable doses of the tincture. 

Fifteen drops three or four times a day, well diluted, will. usually meet the case. 

It may be given in doses of from five to sixty drops in rare instances. it should, however, never be given in larger quantities than twenty minims unless the patient is thoroughly accustomed to the remedy, and has found the usual dose insufficient. 

Otherwise there is danger of getting the physiological effect of the drug, which is pain at the base of the brain. 

When this symptom makes its appearance the medicine should be discontinued for a day or two, and then given in reduced doses. 

There seems to be no danger whatever of forming the habit of taking this drug, as it can be suddenly abandoned at any time without evil consequences, even when given in large quantities. 

In one case it was prescribed by the writer in sixty-drop doses, night and morning, for one year, and then abruptly stopped, nothing being substituted therefore, without bad effects. 

Whenever a quick action is desired, and in all cases where Avena is given to overcome the morphine habit, it should be prepared in hot water. 

It is also a good plan to prescribe it in this fashion wherever indigestion complicates the case. 

The writer has employed this drug in his private practice for a number of years with the most gratifying results. 

He has very rarely found it to fail when indicated, and on account of his high opinion of the remedy he has taken great pleasure in thus bringing it prominently to the attention of the medical profession.
