The berries of this plant are sometimes used, but the bark is the proper medicinal part of the shrub. It is best adapted to the cure of flabby, ill-conditioned ulcers and mortifications, in which a strong decoction is freely used with great benefit. It should be given internally several times a day, as well as applied as a wash and poultice to the parts. A saturated tincture, both of the bark and berries is used internally. THE PRICKLEY ASH. _Its Medical Properties and Use._ The prickley ash has a good reputation in the United States as a remedy in chronic rheumatism. In that disease its operation seems analogous to that of mazorion and guaiacum, which it nearly resembles in its sensible properties. Many physicians place so much confidence in it that it is generally kept by the apothecaries. It is most frequently given in decoction--an ounce being boiled in a quart of water and taken in small quantities, frequently repeated. Dr. George Hayward, of Boston, took it in his own case of chronic rheumatism with evidently good effect; he took a pint of the decoction a day, diluted with water so as to weaken its pungency. The powdered bark may be taken in doses of from 10 to 20 grains, and frequently repeated. Dr. Bigelow says it is also given with good effect in cases of old indolent sores; it is given internally and applied to the sore in the form of a wash. Doctors Barton and Thatcher both speak highly of this medicine. AMERICAN GENTRAURY. _Its Medical Properties and Use._ Every part of this plant is a pure and very strong bitter. It is used in form of tea or tincture and is good for ague and fever. It was used in the yellow fever at Philadelphia with good effect. It may be given even when the fever is on, in such quantities as the stomach will bear. It is not apt to nauseate and is an excellent tonic for the stomach, which improves the appetite and promotes digestion. It is highly recommended by Drs. Barton, Chapman and Elliott, all of whom are physicians of high respectability. DANDELINE. Has been much employed in Germany and the United States, and is certainly a valuable remedy in chronic diseases of the liver and the digestive organs generally. It is also a good remedy in diseases of the spleen. It is beneficial in consumption and as a general alterative when combined with sarsaparilla, and invaluable in scrofula. One ounce of the fresh root, or ½ ounce of the dried, and the same quantity of sarsaparilla put into a pitcher and a pint of boiling water poured on it at night, to be used at pleasure next day, so that all is taken before bed time, or as much more as the stomach will bear. This repeated for a month, produces a fine effect on the system, when the blood needs purifying or in cases of chronic affections of the liver.
