Ôû║ Painless hiccough, starts ten minutes after meal, lasting from fifteen to thirty minutes (first day), . Ôû║ Tightness in left hypochondrium, extending forward to middle line, causing difficulty of breathing, in a warm room, in the evening after sunset; better when walking in the open air; it kept her awake in bed till 1 A.M.; on awaking the next morning, the same; better after a Turkish bath (second and third days), . Ôû║ Numbness of back of right wrist, extending up radial side of arm to just above elbow; felt as if the use of the limb would go (after half an hour); then the same feeling in left wrist, but transient and slighter; afterwards the same (transient) in a small spot on right vertex, rather anteriorly; afterward the same (transient) in anterior portion of right shoulder; the numbness seemed to be in the bone in every case; that in the right arm lasted till she took coffee, which removed it.
Authority. 4, Dr. E. P. Scales, Pub. Mass. Hom. Med. Soc., vol. iv, p. 601. Ôû║ A woman about thirty-five years of age complained of bloated abdomen, with more or less pain; she insisted upon it that she had a tapeworm. I gave the tincture of Filix mas, 15 to 20 drops at a time, at first two or three times a day, on an empty stomach, and then early every morning. Ôû║ The bloating of the abdomen diminished, but there was developed, as I think, on consequence of the Filix mas, a severe prolapsus of the vagina, and pain and tenesmus of the bladder, with copious and frequent emission of urine, with intense pain, which continued until after I abandoned the use of the Filix and gave Chimaphila, and those painful symptoms of vagina and bladder did not return, except in consequence of great fatigue, as long walks, much standing, etc.
Filix Mas was used in the early 1600 as a herbal remedy: The leaves were also used as a remedy for ill health. According to the apothecary John Parkinson, eating them is ÔÇ£sayd to open the belly and moveth it downewards, yet it troubleth the stomacke, and purgeth chollerickeÔÇØ. John Gerard also said of Dryopteris, ÔÇ£it killeth the childe in the mothers wombeÔÇØ; Parkinson shared his views on this matter, but felt the need to clarify a misunderstanding that had arisen from a mistranslation from Greek to English, saying ÔÇ£yet is it but a fable to be any danger unto them to goe or stride over itÔÇØ.
