All living matter contains some sulphur ; this element is therefore essential for life. The greater part of the sulphur in the human body is present in the two sulphur-containing amino acids, methionine and cysteine, or in the double form of the latter cystine. The main purpose of sulphur is to dissolve waste materials. It helps to eject some of the waste and poisons from the system.
It helps keep the skin clear of blemishes and makes hair glossy. It is also valuable in rheumatic conditions.
The main sulphur-containing foods are radishes, carrots, cabbage,cheese, dried beans, fish and eggs. There is no recommended dietary allowance. But a diet sufficient in protein will generally be adequate in sulphur. Deficiency of sulphur may cause eczema and imperfect development of hair and nails.
Sulphur creams and ointments have been remarkably successful in treating a variety of skin problems.
