Kali Carbonicum is a homeopathic remedy prepared from potassium carbonate. In homeopathic practice it is traditionally associated with weakness in the lower back, a tendency to swelling of the upper eyelids, and a sensitive, duty-bound temperament, with complaints that are notably worse in the small hours of the morning.
Here we cover where it comes from, the complaints it has traditionally been linked to, the symptom picture that points to it, and the forms and potencies you are likely to meet.
The short version: A potassium-carbonate remedy classically linked with low-back weakness, upper-eyelid puffiness and 2 to 4am aggravation.
What is Kali Carbonicum and where does it come from?
Kali Carbonicum is prepared from potassium carbonate, one of the classic mineral salts, historically obtained from wood ash (potash). It is diluted and succussed to make the homeopathic remedy.
The kali salts as a group are known in homeopathy for a sense of weakness and for rigid, dutiful characters; Kali Carbonicum is the best-known member.
What is Kali Carbonicum traditionally used for?
The whole picture guides the choice. Kali Carbonicum is traditionally associated with:
- Weakness and aching in the small of the back, sometimes feeling as if it would give way.
- Puffy swelling of the upper eyelids, a well-known keynote.
- A tendency to feel worse between 2 and 4am.
- Sensitivity to cold and draughts, and a chilly constitution.
- A rigid, conscientious, easily startled temperament.
Who typically reaches for it?
The classic Kali Carb picture is a dutiful, principled person who feels weak in the back, chilly and easily startled, and who wakes in the early hours feeling worse. A puffy little swelling over the upper eyelids is often mentioned as a pointer.
Symptoms are typically worse in the early morning hours, from cold and draughts, and better in warmth and from firm pressure or support to the back.
What forms and potencies does it come in?
Like most classical remedies, Kali Carbonicum is prepared by serial dilution and succussion from its source material. You will most often see it in small lactose pillules or tablets, and sometimes as liquid drops or in combination formulas alongside complementary remedies.
In home self-care it is commonly used in low to medium potencies such as 6C or 30C. Lower potencies are often chosen for more physical, everyday complaints, while 30C is a popular general-purpose strength. Higher potencies are usually reserved for guidance from an experienced homeopath.
