Unpublished paper, 'Physiological action of the bark of Erythrophleum guinense' by T [Thomas] Lauder Brunton and Walter Pye

Description

Brunton and Pye describe some of the effects of Erythrophleum guinense on the body, including: that it diminishes oxidation, and thus prevents fresh vegetable tissues from communicating a blue colour to tincture of guaiac; that it does not hinder the development of the yeast-fungus nor the germination of seeds, and Penicillium grows freely in a solution of it; that a watery solution of the alcoholic extract prevents the development of bacteria, but one of the watery extract does not do so; that it does not destroy the life of bacteria or infusoria, and the motion of cilia is not arrested by it; that it arrests amoeboid movement in leucocyte; that it has no action on fresh muscular fibre, but muscular tissue, when kept in a solution of the alcoholic extract for some days, undergoes extensive fatty metamorphosis, but does not become putrid.
