Anacardium Occidentale
By Constantine Hering — The Guiding Symptoms of our Materia Medica
Cashew Nut. Anacardiaceæ.
The common cashew nut of the West Indies. It is easily distinguished from our Anacardium which comes from the East Indies, by its being kidney-shaped, while the Oriental nut, our well-proved medicine, is heart- shaped. It was never proved and is only known by the frequent cases of poisoning which occur from peeling or roasting the nut. The kernel is edible, but it is advisable first to remove the germ between the halves.
The poisonous black juice contained between the outer and inner shell contains two peculiar principles, Anacardic acid and Cardol. Poisonings are frequently mistaken for Rhus poisoning.
The effects on the skin are mentioned by C. Hg. in Cl. Müller's Vierteljahrschrift in 1861, Vol. 12, p. 276. No cures on record excepting from Segin in Hygea.
