What is Salt Under Tongue?

The practice of placing salt under the tongue is a method used to rapidly deliver sodium into the bloodstream. Unlike the traditional way of consuming salt, which involves ingesting it through food, this method takes advantage of the sublingual mucosal route. This area beneath the tongue is highly vascularized, meaning it has numerous blood vessels that can quickly absorb substances. When salt is placed under the tongue, it dissolves and passes directly into the bloodstream, bypassing the digestive system.

This technique is often used for its purported health benefits, which range from balancing electrolytes to enhancing hydration levels. By using this method, individuals aim to quickly address an electrolyte imbalance or dehydration, especially in situations where rapid intervention is necessary. However, it is essential to understand the correct dosages and types of salt that should be used to avoid any adverse effects.
