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.
What Allium Cepa is used for
- Colds with a streaming, watery nasal discharge
- Hay fever with sneezing and burning nose
- Bland, non-irritating watering of the eyes
- A raw feeling under the nose from the acrid discharge
- Symptoms worse in a warm room and better in open air
Characteristic symptom picture
Homeopaths look for these guiding features when considering Allium Cepa.
- Burning, acrid nasal discharge that irritates the upper lip
- Bland, profuse watering of the eyes
- Violent sneezing, especially entering a warm room
- Better in the open air, worse indoors and in the evening
- A tickling cough that makes the person grasp the throat
Potency
Allium Cepa is available in several potencies such as 6C, 30C and 200C, as well as lower and mother-tincture forms in some cases. The right potency and repetition depend entirely on the individual case and are decided by a qualified homeopath - this page gives no dosing instructions.
The Allium Cepa picture and modalities
Allium Cepa mirrors the effect of a cut onion: a burning, acrid nasal discharge that makes the upper lip raw, together with bland, profuse tears. Sneezing is violent, often on entering a warm room, and the symptoms ease in open air and worsen indoors and towards evening. A tickling laryngeal cough can make the person clutch the throat. A homeopath weighs the acrid-nose, bland-eye contrast and the open-air amelioration within the whole picture.
Before you consider Allium Cepa
This is background information, not advice to self-treat. Persistent or severe hay fever and colds that will not settle deserve medical assessment, and asthma or breathing difficulty always needs conventional care. In homeopathy the right remedy and potency are chosen for the whole individual by a qualified practitioner, and the same remedy does not suit everyone. Homeopathy should complement, not replace, conventional care.

Frequently asked questions
What is Allium Cepa used for in homeopathy?
It is an informational materia-medica remedy classically associated with streaming colds and hay fever - a burning nasal discharge with bland, watery eyes. A homeopath matches it to the whole picture rather than prescribing it by name alone.

Should I take this remedy myself?
Self-medication is discouraged. The correct remedy and potency depend on your whole individual symptom picture and should be chosen by a qualified homeopath.
Is it safe alongside other treatment?
