Anions are ions with more electrons than protons, giving it a net negative charge. The contrary would be a cation, an ion with fewer electrons than protons, giving it a positive charge. Positive ions are considered harmful to the human body, while negative ions are considered beneficial.

Ions are ubiquitous in nature and are responsible for diverse phenomena from the luminescence of the Sun to the existence of the Earth’s ionosphere. Atoms in their ionic state may have a different colour from neutral atoms, and thus light absorption by metal ions gives the colour of gemstones. In both inorganic and organic chemistry (including biochemistry), the interaction of water and ions is extremely important.

“Anion” sanitary napkin has an anion strip inside the cotton setting, which emits high density of anions when used. During the process of anion neutralization, the released oxygen could suppress the major source that causes gynecological diseases.

The generation of anaerobe decreases the odds of gynecological diseases and the whole process is chemical free. An average female’s vaginal PH reading is 4.0 to 5.5.
