Sodium bicarbonate is the main component of baking soda. In cooking, baking soda is used as a leavening agent in breads, cakes, pancakes, and other baked goods. It can be used to smother a fire, and as an antacid, to help lower the acidity in blood and urine, and to lower high potassium levels. Sodium Bicarbonate is also great as a cleaning agent (household cleaner and for personal hygiene)as it kills yeast/fungal infections and is an effective odor remover.
Although rare, it is possible to have an allergic reaction to cleaning with Sodium Bicarbonate. Symptoms can include hives, itching and swelling. In accidental overdose (ingestion), symptoms can include diarrhea, vomiting, muscle spasms and seizures.
Sodium Bicarbonate is not a human carcinogen; in fact, in some cases, it is being used to help in cancer treatments.
