👉 A minus fluid, also known as a negative fluid or an antidote to acid, is a substance used to counteract the effects of acidic substances in the body, such as stomach acid or gastric juices. It works by neutralizing excess acidity, thereby reducing irritation and damage to the stomach lining. Common examples include antacids like aluminum hydroxide, magnesium hydroxide, and calcium carbonate, which are often used to alleviate symptoms of acid reflux, heartburn, or ulcers. Unlike some other antacids that simply provide temporary relief, minus fluids aim to restore the body's natural pH balance and promote healing of affected tissues.
