Sulfur powder represents a refined form of the bright, yellow element that resembles baby powder. When burned, it produces a very strong odor similar to rotten eggs, and a bright, blue flame. Sulfur powder in its pure form might treat acne and other skin problems. It is considered an essential element to all life and is available in the human body as biotin and thiamine. Enzymes use sulfur for antioxidant functions.

In the past, most sulfur powder came from mines and volcanic activity. It was ground from rocks and salt domes of fossilized minerals through a hot water process that melted sulfur and produced pure powder. These processes were used up until the 20th century, when the element became scarce and too expensive to mine.

Most modern sulfur comes as a byproduct of the petroleum refining process and natural gas industry, in the form of hydrogen sulfide gas. This gas is converted to usable sulfur used in fertilizers, gunpowder, matches, and detergents. The rubber, plastic, and paper industries also use sulfur extracted from sulfuric gases.

As a dietary supplement, sulfur powder might treat bacterial infections on the skin or internally. It might stimulate the production of bile and boost the immune system by protecting the body from pollution and radiation exposure. Historically, sulfur powder was used as a laxative and diuretic. It also treated gout, scurvy, spasms, and rheumatism.

Sulfur has made up the base for sulfa drugs used as a primary antibiotic for decades. It was used to treat viral infections and parasites. Sulfur powder is used in Chinese medicine to treat acne, ringworm, psoriasis, and eczema. The powder can be purchased in its pure form and mixed with cream or bought as a ready-to-use ointment.

Health experts say sulfur as a food additive is safe in very small amounts. The mineral might burn the eyes, tissues, and lungs after they are exposed to sulfuric gases. Acid rain could come from coal and petroleum production, and from power plants that extract sulfuric acid, which might cause environmental harm to soil and water resources. In some regions, improved environmental standards address these concerns.

Sulfur is referred to as brimstone in the Bible, which led to the term hell and brimstone. It is considered an element of fire used in exorcism and magic. This element has been used in magic rituals to remove hexes or spells and to protect people from harm.

Garlic contains ample amounts of the chemical. Sulfur can also be found in Brussels sprouts, onions, cabbage, and turnips. Wheat germ and some beans, including soybeans, also contain sulfur. In the human body, several amino acids rely on sulfur for proper functioning.
