Sodium bicarbonate (IUPAC name: sodium hydrogencarbonate), commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO3. It is a salt composed of a sodium cation (Na+) and a bicarbonate anion (HCO3−). Sodium bicarbonate is a white solid that is crystalline, but often appears as a fine powder. It has a slightly salty, alkaline taste resembling that of washing soda (sodium carbonate). The natural mineral form is nahcolite. It is a component of the mineral natron and is found dissolved in many mineral springs. Nomenclature
Because it has long been known and widely used, the salt has many different names such as baking soda, bread soda, cooking soda, and bicarbonate of soda and can often be found near baking powder in stores. The term baking soda is more common in the United States, while bicarbonate of soda is more common in Australia, United Kingdom and Ireland. and in many northern/central European countries it is called Natron. Abbreviated colloquial forms such as sodium bicarb, bicarb soda, bicarbonate, and bicarb are common.The word saleratus, from Latin sal æratus (meaning "aerated salt"), was widely used in the 19th century for both sodium bicarbonate and potassium bicarbonate.Its E number food additive code is E500.The prefix bi in bicarbonate comes from an outdated naming system predating molecular knowledge in reference to the two molar equivalents of carbon dioxide (known as carbonic acid in the ancient chemistry language) that potassium hydrocarbonate/bicarbonate releases upon decomposition to (di)potassium carbonate and to potassium oxide (potash).
These cases are more likely in those who are immunocompromised. Diagnosis
Vulvovaginal candidosis is the presence of Candida in addition to vaginal inflammation. The presence of yeast is typically diagnosed in one of three ways: vaginal wet mount microscopy, microbial culture, and antigen tests. The results may be described as being either uncomplicated or complicated. Uncomplicated
Uncomplicated thrush is when there are less than four episodes in a year, the symptoms are mild or moderate, it is likely caused by Candida albicans, and there are no significant host factors such as poor immune function. Complicated
Complicated thrush is four or more episodes of thrush in a year or when severe symptoms of vulvovaginal inflammation are experienced. It is also complicated if coupled with pregnancy, poorly controlled diabetes, poor immune function, or the thrush is not caused by Candida albicans. Recurrent
About 5-8% of the reproductive age female population will have four or more episodes of symptomatic Candida infection per year; this condition is called recurrent vulvovaginal candidiasis (RVVC). Because vaginal and gut colonization with Candida is commonly seen in people with no recurrent symptoms, recurrent symptomatic infections are not simply due to the presence of Candida organisms. There is some support for the theory that RVVC results from an especially intense inflammatory reaction to colonization. Candida antigens can be presented to antigen-presenting cells, which may trigger cytokine production and activate lymphocytes and neutrophils that then cause inflammation and edema. Treatment
The following treatments are typically recommended:

Intravaginal (vaginal suppository): butoconazole, clotrimazole, miconazole, nystatin, tioconazole, terconazole.
