This is general information about a homeopathic remedy, not a prescription or dosing advice. In homeopathy the correct remedy and potency are chosen for the whole individual symptom picture by a qualified homeopath — the same remedy is not right for everyone. Do not self-medicate, and consult a qualified homeopathic doctor (and your physician for serious or persistent conditions) before taking any remedy.
Homeopaths look for these guiding features when considering Drosera Rotundifolia.
Drosera is commonly used in 30C and 200C; potency selection is a clinical decision for your homeopath.
Drosera's picture is a violent, spasmodic, barking cough of the kind seen in whooping cough — deep, hoarse and croupy, coming in rapid fits that follow one another in quick succession. A keynote tickling in the throat, as if from a feather or crumbs, sets off the spasm, and the fit may end in gagging or retching. The cough is markedly worse after midnight and after lying down. This is a recognisable cough pattern, not a diagnosis, and it fits only some people whose spasmodic, night-worse cough genuinely corresponds to it.
This page is informational only, not a prescription. In homeopathy the remedy and potency are matched to the whole individual by a qualified homeopath, who weighs the full picture rather than one keynote — never self-select a potency from what you read here. A spasmodic cough deserves medical attention if there is breathing difficulty, a cough in a young infant, high fever, coughing of blood, or a cough lasting beyond three weeks; suspected whooping cough especially needs proper care. Use this only to understand the remedy's traditional picture, and seek assessment for severe symptoms.
It is the leading remedy for a violent, spasmodic, barking cough — including whooping-cough type — worse at night and after lying down. The right remedy still depends on your picture.
It is the most-considered remedy for whooping-cough type spasmodic fits, but whooping cough (especially in infants) needs medical care and the page is informational only.
A keynote of Drosera is a spasmodic cough worse after midnight and on lying down; a homeopath uses such features to individualise the remedy.
For breathing difficulty, a cough in a young infant, high fever, coughing blood, or a cough lasting beyond three weeks.
The right remedy and potency are chosen for your individual case. Book an online or in-clinic consultation with a qualified homeopath.
