"Sulfur has been used medicinally since ancient times and it is contained in every cell in your body. It is a component of three different amino acids (the building blocks that make up protein). Approximately 0.25% of your total body weight is sulfur. It is most concentrated in keratin, which gives you strong hair, nails and skin. It is known as "nature's beauty mineral" because your body needs it to manufacture collagen, which keeps your skin elastic and youthful. Sulfur is used primarily to ease the red, itchy rashes of conditions such as eczema and diaper rash. It also helps protect your body against toxins in the environment. In addition, people with arthritis may find pain relief from taking a soothing bath in hot sulfur springs." Read more about sulfur:

"Sulfur is a part of many bacterial defense molecules. For example, though sulfur is not part of the lactam ring, it is part of most beta lactam antibiotics, including the penicillins, cephalosporins and monobactams."
