A salt flush, often termed a saltwater cleanse, is a practice intended to rapidly clear the contents of the digestive tract. It involves consuming a specific mixture of water and non-iodized salt to create a powerful, temporary laxative effect. The goal is to induce a series of watery bowel movements that proponents believe cleanse the colon. This technique is a quick, at-home method for digestive tract clearance, not a long-term health strategy.
Why People Use Salt Flushes
Many individuals turn to this method seeking immediate relief from acute constipation or persistent bloating. The high concentration of salt creates an osmotic effect, drawing water from the body’s tissues directly into the intestines. This influx of fluid softens stool and increases the volume of intestinal contents, stimulating the colon muscles to expel waste rapidly.
The practice is also popular among those undertaking fasting or “detox” protocols, such as the Master Cleanse. Proponents often claim the flush helps eliminate accumulated “toxins” or old, impacted fecal matter. While the procedure results in rapid bowel movements, there is no scientific evidence supporting the claim that it removes toxins beyond what the body’s natural elimination systems already handle.
Essential Preparation and Ingredients
The effectiveness of the flush relies on using the correct ingredients and ratio to ensure the solution is hypertonic, or saltier than the body’s fluids, so it is not absorbed. Use two teaspoons of non-iodized sea salt, such as Pink Himalayan or Celtic salt, avoiding common table salt which may contain iodine and anti-caking agents. This salt must be combined with one quart (four cups or one liter) of filtered water.
The water should be warmed to a comfortable, lukewarm temperature, similar to body temperature, which helps the salt dissolve fully and makes the mixture easier to consume. The flush must be performed on a completely empty stomach for optimal results. This usually means first thing in the morning, or at least two hours after your last light meal.
Step-by-Step Guide to the Salt Flush
Begin by combining the two teaspoons of non-iodized salt with the one quart of warm, filtered water in a container with a lid. Shake or stir the mixture vigorously until all the salt granules are completely dissolved. Undissolved salt can irritate the stomach lining or reduce the effectiveness of the process.
The entire solution must be consumed quickly, ideally within five to ten minutes, to ensure the hypertonic effect is activated simultaneously throughout the digestive tract. Sipping slowly may cause the stomach to absorb some salt, potentially leading to nausea or vomiting without the desired laxative outcome. After consumption, some individuals lie down on their right side for a few minutes before switching to their left side. This position is thought to help guide the solution into the small intestine, where the osmotic action begins.
What to Expect During and Immediately After
The onset of the effects typically occurs within 30 minutes to two hours following consumption. The process is characterized by a series of urgent and powerful bowel movements. These movements will be liquid and watery, as the colon is flushed with the saline solution and the fluid it has drawn in.
You should plan to remain at home and stay close to a restroom for the next several hours, as the cleansing process can continue for two to three hours. It is common to experience mild sensations like gurgling, bloating, or stomach cramping as the solution moves through the intestines. Once the flush is complete, reintroduce plain water or mineral-rich liquids to rehydrate the body.
Safety Considerations and Who Should Avoid It
Consuming a large volume of salt presents significant health risks due to potential excessive sodium intake. The rapid fluid loss can easily lead to dehydration and a dangerous electrolyte imbalance, which may manifest as weakness, muscle spasms, or an irregular heartbeat. Some people also experience strong side effects, including intense nausea and vomiting.
Individuals with specific medical conditions should never attempt a salt flush without medical supervision. The high sodium load is particularly dangerous for anyone with high blood pressure, heart problems, or kidney disease, as it can strain the cardiovascular and renal systems. People with gastrointestinal disorders, such as inflammatory bowel disease or ulcers, or those who are pregnant should avoid this procedure entirely. Always consult a healthcare professional before attempting a salt flush.
