Filix Mas.

Male Fern. N. O. Filices. Tincture of fresh root, or fresh root grated.

Clinical.-Abdomen, bloated. Abortion. Blindness. Sterility. Tapeworm.

Characteristics.-Male fern has been recognised as a vermifuge from the time of Galen, and Dioscorides credits it with the power of causing sterility and abortion. A fragmentary proving in Allen's Appendix records a case in which 15 to 20 drops of the tincture given three times a day to a woman suffering from bloated abdomen with more or less pain caused diminution of the bloating, but also: Severe prolapse of vagina, pain and tenesmus of bladder with copious and frequent emission of urine with intense pain. Filix was discontinued and then Chimaphila relieved. The symptoms did not return afterwards, except after much walking and standing. Hering says the best time to give the drug for expulsion of tapeworm is in the summer when the fresh root can be obtained. If an ounce of the grated root is given in the forenoon, usually the tapeworm comes away in the afternoon. Among the leading symptoms are: Pale face with blue rings round eyes; gnawing, boring pains in abdomen, < after sweet things. Blindness has been caused in a number of cases from atrophy of the optic nerve. C. S. Spencer records this effect from taking capsules each containing ten minims of the oil of male fern for tapeworm: "A feeling of nausea; abdomen became painfully distended with colicky pains. Menses returned after only one week's absence, and continued profusely for three weeks. Very sick after taking her food. The worm was got rid of and the capsules stopped when these symptoms passed away.

Teste has used it successfully in a case of violent dyspnoea without cough, with stitches in region of heart and obscure symptoms of pericarditis. The patient was a young lady of lymphatico-nervous temperament, and was much weakened by long sickness.
