Concerning the use of this vegetable in calculous affections, we can say nothing from our own experience ; but it will appear from the sequel, that it is not destitute of activity, and as there is such a striking analogy subsist- ing between a medicine which we have found so often to relieve; and this, which we have not tried, it is presumable, that it may succeed when the other is ineffectual; as certain astringent and bitter articles do after the exhibition of bark in intermittents.
