Salt water flushing: a fast, easy, mini gut-reset.

Why salt flush? A natural colon cleanse for better gut health and energy balance.

Most people carry several kilograms of old, stagnant waste in the colon without realising it. Over time, this waste can ferment, stagnate, and reabsorb back into the bloodstream, contributing to symptoms such as:

• Low energy

• Bloating and abdominal discomfort

• Brain fog

• Constipation or sluggish bowels

• Poor digestion

• Immune stress

Stagnant waste can also place extra load on the liver and may worsen issues like leaky gut or inflammation.

We clean the outside of our bodies daily; brushing teeth, showering, scrubbing our skin… yet our digestive tract is over 8 meters long and rarely receives this kind of attention. A salt flush provides a fast, simple gastrointestinal clean-out that supports natural detoxification and digestive reset.

What is a salt flush? (salt water flush explained)

A salt flush, also known as a Salt Water Flush (SWF), involves drinking a mixture of warm water, natural sea salt, and optionally lemon juice or apple cider vinegar.

This creates a rapid, osmotically driven bowel flush that moves quickly through the digestive tract. The salt solution helps pull water into the intestines and sweep out:

• Old waste

• Mucus build-up

• Pathogens

• Toxins

• Digestive sludge

Unlike laxative herbs, which stimulate peristalsis, a salt flush works mechanically, helping the colon cleanse itself efficiently.

Benefits of a salt water flush:

• Improved digestion

• Reduced bloating

• More regular bowel movements

• Clearer skin

• Increased physical energy

• Better mental clarity

• A lighter, “cleaner” overall feeling

• Improved mood

These are key reasons many use salt flushing as part of their gut healing, detox support, or digestive reset routines.

How to do a salt flush (the correct method)

Most people feel the effects within 45–60 minutes.

The Mix

Drink the following within 5 minutes:

• 300–450 ml warm, filtered water

• 2 tablespoons natural high quality sea salt

• Juice of 1 lemon or 1 tbsp apple cider vinegar

Also drink 600 ml plain filtered warm or room-temperature water during this 5 minutes.

This helps move the salt solution through the stomach and into the intestines, where the flushing happens.

What to expect during a salt flush

• The first bowel movement usually begins 30–60 minutes after drinking.

• You may have multiple waves of elimination every 15–30 minutes.

• Temporary lightness, weakness, or fatigue is normal during rapid release.

• Some people stay near the bathroom for 1–2 hours.

• Mild cramping can occur and is usually manageable.

Within 24 hours, many people report:

• Clearer thinking

• More energy

• A calmer, happier mood

• Reduced bloating

• A flatter stomach

• A “reset” feeling through the whole gut

What to Eat After the Flush

Avoid food for 2 hours after the flush.

When you do reintroduce food, choose:

• Anti-inflammatory foods

• Homemade broths

• Fermented foods to help repopulate gut bacteria

• Warm, easy-to-digest meals

Hydration is essential. Structured hydrogen water can be especially supportive after a flush — you can learn more about its benefits here.

How often should you do a salt flush?

I recommend up to 2–3 times per month only. A salt flush is meant to be an occasional digestive reset, not a daily or frequent practice. I suggest booking a consult with Sarah if you feel you need to flush often to address constipation or other symptoms of poor gut health.

Who should avoid a salt flush?

Avoid salt flushing if you have:

• Crohn’s disease

• Ulcerative Colitis

• IBS (in some cases)

• High blood pressure

• Kidney issues

• Severe dehydration

• Heart conditions

• Pregnant

For the above conditions, you could consider working with Sarah to reduce your symptoms and reverse disease progression.

Is a salt flush right for you?

When done properly, a salt flush can be an effective natural method to boost digestion, reduce bloating, and aid both physical and mental clarity. It clears the colon quickly, supports detoxification, and helps your gut return to a state of balance, especially after overeating, travel, stress, or periods of sluggish bowel function.
