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.

The characteristic picture & modalities

Causticum is a deep remedy associated with gradual, creeping weakness or even paralysis, such as of the face or vocal cords, with hoarseness and loss of voice. Its skin keynote is old, large warts on the face, eyelids and fingertips, and there is often stress incontinence, leaking on coughing or sneezing. Sensations tend to be raw, sore and burning, in a deeply sympathetic person affected by injustice. It is worse in dry, cold weather and better in damp. This recognisable pattern fits some individuals; it is not a diagnosis.

Before you take Causticum

In homeopathy the remedy and potency are matched to the whole person by a qualified homeopath, not chosen from warts or weakness alone. This page is background reading rather than a prescription, and you should not self-select a remedy or set a potency from it. Suspicious or changing skin growths must be medically checked, and gradual weakness, urine leakage or voice loss should be properly investigated. For severe or persistent symptoms, seek a clinical evaluation first and let your homeopath confirm whether this picture genuinely suits you.
