Mannitol

Mannitol is a type of sugar alcohol used medically as a diuretic and to reduce swelling caused by brain or eye conditions. It works by drawing excess fluid out of tissues and into the bloodstream, helping to lower pressure in the head or eyes. Mannitol is often administered intravenously in hospitals for emergency cases like brain swelling or high eye pressure. It is also used in some medical tests and as a supplement in certain products. Because it influences fluid balance, it should only be used under medical supervision to avoid potential side effects like dehydration or electrolyte imbalance.
