Drosera Rotundifolia. (Sundew.)
We employ a tincture of the fresh plant prepared in Germany, using it in the proportion of: Rx Tincture of Drosera, gtts. x. to ʒj.; Water, ℥iv. A teaspoonful every three or four hours.
I use the Drosera as a specific in the cough attending and following measles, especially where there is dryness of the respiratory mucous membranes. An experience of ten years with it, in a large number of cases, has given me great confidence in the remedy.
We also use it in cases of whooping cough, especially where there is dryness of the air-passages, and much irritation of the nervous system. Whilst it is not a remedy for all cases of whooping cough, it is a true specific in those to which it is adapted. I have often seen a serious case of the disease relieved in twenty-four hours, and an entire arrest of the cough in two weeks.
We also employ it in cases of chronic cough, with dryness of the air-passages and nervous irritation, with much advantage. It makes little difference whether it arises from bronchial irritation or inflammation or phthisis, if associated with irritation of the basilar portions of the brain, and pneumogastric.
