Kali bicarbonicum

Kali bicarbonicum has first appeared in the literature for its homoeopathic use in 1855. Following this report, its mention is also found in pharmacopoeia(s) and other reputed journals. However, it is not a fully proven drug. Its application in homoeopathy is mainly based on its action on cellular pathology and symptoms produced by it in large doses.

Role of potassium as the principal intracellular cation in many body tissues is well established. Potassium ions’ concentration in the body is essential for nerve conduction especially in specialized tissues like brain, heart and skeletal muscle. It helps to maintain normal renal function, acid-base balance, and cellular metabolic functions. Especially, Kali bicarbonate is helpful in the release of carbon dioxide. Due to this effect, this drug produces excessive eructation. This drug is also used as an antacid, electrolyte replenisher and potassium supplement in low doses. Many drug formulations contain it as an excipient. In low doses, it neutralizes gastric acid in a short timeframe after ingestion and the effect is soon overcome by meal-stimulated acid secretion.

Like all Potassium Salts, the weakness characteristic is also seen in this drug. It is characterized by soft pulse, coldness, general depression, and characteristic stitches felt in different parts of the body and different conditions. Characteristic sharp and cutting pain of all Kalis is also applicable for this drug, with nearly all these symptoms better by motion. As per T. F. Allen, Salts of Potash should never be used in fevers. Tenacious and slimy discharges are characteristics. Many of its symptoms resemble the symptoms of two Kali group drugs viz. Kali bichromicum and Kali carbonicum. A compilation of symptoms derived from these two drugs are systematically presented below:
