Drug Used, Its Collection, Preservation, Etc. 
The rhizomes directed by all of the present day pharma¬ 
copoeias to be used in the preparation of the oleoresin of as- 
pidium are those of the male fern 1 now referred by botanists 
to the genus Dryopteris as Dryopteris Filix-mas (Linne) Schott. 
As male fern, especially in the older works on pharmacy, has been 
referred to genera other than Dryopteris, the following table of 
botanical synonyms is given: 
1 The rhizomes of ferns other than those which have been officially recog¬ 
nized are said to yield oleoresins which are active in the expulsion of the 
tapeworm. 
Kuersten states that the rhizomes of Aspidium athamanticum Kunze yield 
a preparation which is as active as that obtained from male fern. Arch, 
d. Pharm. (1891), 229, p. 258. 
Lauren reports the use of an extract in Finland prepared from Aspidium 
spinulosum Sw. which he states is very active as a teniafuge. Finska 
Laegaresaellck. Handl. (1897), p. 9; Pharm. Centralh, (1897), 39, p. 775. 
Rosendahl suggests that the rhizomes of Dropteris dilata replace those 
of Dryopteris Filix-mas in the preparation of the official oleoresin as he has 
found them to be four times as active as the latter in the expulsion of 
Bothryocephalus latus. Hygienic Lab. Bull. No. 87, p. 250.
