Therapy: This agent is indicated not only to correct the atonic conditions of the glandular structure of the gastro-intestinal apparatus in malaria, but as an antidote to the malarial poison itself. It has marked control over many of the manifestations of malaria.
Its influence upon the stomach in these cases increases the appetite at once, improves the character of the digestion and relieves the drowsiness and dullness apt to follow imperfect digestion. It is a tonic in enfeebled conditions of the stomach from whatever cause and improves intestinal digestion."
