This remedy is a stimulant to the digestive and blood-making organs, and may be advantageously employed for the general purposes of a tonic. But beyond this, it influences the vegetative processes, probably through the sympathetic system of nerves, strengthening the circulation, aiding nutrition, and the removal of waste. We have used it but little, yet the testimony in its favor is such, that we strongly recommend its trial.
