salt
From Trekipedia
Also known by its chemical composition sodium chloride, salt was an essential nutrient for Human physiology, particularly in desert climates, and was also used in food preparation. The M-113 creature was particularly dependent upon the substance, and had evolved the ability to draw salt directly from another life form via suction cup-like appendages on its hands.[1]
