Walnut Tree. Nat. Ord. Juglandeae. Hab. Persia, but cultivated in various parts of Europe.
Med. Prop. and Action. The bark of the root is stated to be rubefacient, and the inner bark of the stem emetic. The green rind of the fruit was formerly regarded as anti-syphilitic and anthelmintic, but is now rarely employed. The leaves have been extolled as alterative and deobstruent.
In Syphilis, the green rind of the fruit was greatly extolled by Petrus, Borellus, Ramazzini, Gir-tanner, and others. Mr. Pearson* states that, in constitutional Syphilis, he has seldom employed it without manifest advantage; but it has now quite fallen into disuse.
Negrier, of Angers. He has published three memoirs on the subject: the first in 1841, the second in 1844, and the third in 1850. § In the last, he adduces evidence in its favour from Drs. Brogiolli, Nasse, and Kreutzwald. From extensive observations, he draws the following conclusions: - 1, Scrofulous affections admit of a radical cure by the preparations of Walnut leaves; 2, the action of this medicine is so constant that we may count upon the successful treatment of a great number of patients by its use; 3, the action of Walnut leaves is slow, innocuous, and durable; 4, Scrofulous diseases of the skin, and of the lymphatic glands, are cured more speedily and surely by Walnut leaves than by any other medicine; so are also ophthalmic affections of a strumous nature. The proportion he uses is a handful of leaves to Oj. of boiling water, of which fiv. are taken twice daily. He also recommends an extract prepared by evaporation. A strong decoction he uses as a wash for scrofulous ulcers. Maurther, of Vienna, regards it as a remedy of unquestionable efficacy; but Dr. Ranking,|| of Norwich, states that his experience of the remedy is not sufficiently encouraging to induce him to substitute it for Cod Liver Oil or Iodine.
