Causticum (potassium hydrate) in homeopathy: properties, benefits and uses (all you need to know)

The homeopathic remedy Causticum, or potassium hydrate, is obtained by a very complex process in which a “fusion” of different minerals and chemical elements takes place: slaked lime, potassium bisulfate and water. It was produced and tested in the early nineteenth century by Hahnemann, who noted that this remedy caused an astringent sensation and a spicy taste under the tongue.

Causticum: origin and preparation of the remedy

The basic substance of the remedy, as already mentioned, is lime powder: in a porcelain mortar about 60 g of this powder are mixed with potassium bisulfate and boiling water until a paste is obtained that is then distilled with a specific procedure. The distillate produced contains the concentrated Causticum which, finally, is prepared to the right potency.

Causticum looks like a colorless and clear liquid like water, with an astringent taste. It freezes at low temperatures, has caustic effects and is able to promote putrefactive processes in animal tissues.

Causticum : homeopathic remedy

Causticum is a homeopathic remedy used especially for paralysis or weakness of the nerves and muscles of the bladder, larynx, vocal cords, upper eyelids or right side of the face.
