A nonmetal, sulfur is the 10th most abundant element in the universe, according to the Jefferson National Linear Accelerator Laboratory. Today, it's most common use is in the manufacture of sulfuric acid, which in turn goes into fertilizers, batteries and cleaners.
First, sulfur is an element of the earth. This element is essential to life, and is the eighth most prevalent element in the human body. No one is allergic to sulfur itself. Sulfur is not present as an isolated element in the body, but in combination with other elements and, most often, in complex molecules. The primary placement of sulfur in the human body is in the sulfur-containing amino acids: methionine, cysteine, homocysteine (and related cystine, homocystine), and taurine.
