Potassium nitrate is a compound of potassium with the molecular formula KNO3. This colorless chemical compound is found pure in nature as the mineral saltpeter, or nitre. Potassium nitrate is a crystalline salt that resembles table salt. It is used as a diuretic. People have been using potassium nitrate as a cure-all for everything from stomach ailments to arthritis. Potassium nitrate has been controversially ascribed with anti-aphrodisiac effects and is supposed to inhibit erections in men.


Potassium nitrate is a colorless and odorless crystal or powder when ground up. Its liquid form boils at 400 degrees Celsius (752 degree Fahrenheit), and its solid form melts at 333 degree C (631 degree F). It is soluble in water and reacts with various chemicals (except phosphites, organic compounds, other heavy metals and strong acids).

Potassium Nitrate as Medicine

People may wonder why potassium nitrate is called a medicinal element because its use in gunpowder as an oxidation element is well known. History has evidence that it was mined by the Confederate Army, which maintained a Confederate Nitre Bureau at the time of the Civil War.

Researchers have discovered the potential of potassium nitrate as a medicine. If taken under medical supervision in small dosages, medical potassium supplements are known to lower blood pressure. Medical Education Online reports that "potassium supplements, 40-80 mEq/day, lower blood pressure, an effect that is largely lost in patients who are also on a low sodium diet." The scientific community continues to be uncertain about the way in which potassium is related to high blood pressure and vascular diseases. Potassium and blood pressure appear to be inter-related through changes in sodium excretion.

Effects on Nervous System

The basic ion of the fluids in your body cells is potassium. It is known to improve functioning of muscles and nerves when added with sodium, creating the nervous system’s electrical potential. If a person has episodes of vomiting or diarrhea and loses fluid in large amounts, there is a probability of losing potassium as well. This can lead to paralysis of the muscles; on the other hand, if there is an overload of potassium, the person may suffer a heart attack. According to Drugs.com, "It (potassium nitrate) is also used to help reduce painful sensitivity of the teeth to touch; sweets; or hot, cold or acidic substances."
