Andreas Moritz Liver Flush Protocol: Complete Step-by-Step Guide

The liver flush is one of the most controversial protocols in natural health. Critics call it pseudoscience. Proponents claim it changed their lives. Thousands of people around the world have expelled what appear to be gallstones without surgery — sometimes hundreds of them in a single flush.

Andreas Moritz, a German naturopath, spent decades refining and popularizing this protocol. His book The Amazing Liver and Gallbladder Flush has sold over a million copies and spawned countless variations. The protocol itself predates Moritz — versions appear in European folk medicine for centuries — but his systematic approach made it accessible to modern practitioners.

Here's the reality: this protocol is intense. It's not comfortable. It requires preparation, commitment, and understanding of what you're actually doing. But for people with sluggish bile flow, chronic liver congestion, or suspected gallstones who want to avoid surgery, it remains one of the most powerful tools available.

This guide covers the exact Moritz protocol, what to expect, what you'll see, and how to do it safely.

What the Liver Flush Actually Does

Before diving into the protocol, understand the mechanism. This isn't magic — it's physiology.

The Bile Flow Problem

Your liver produces 400-800ml of bile daily. This bile flows through the hepatic ducts, into the common bile duct, and either into the gallbladder (for storage) or directly into the small intestine (for fat digestion).

When bile becomes thick, sluggish, or supersaturated with cholesterol, it can form deposits: bile sludge, crystallized cholite, and eventually gallstones. These deposits accumulate in the bile ducts within the liver itself (intrahepatic stones) and in the gallbladder.

Most people think gallstones only exist in the gallbladder. This is incorrect. The majority of stones form in the intrahepatic ducts — the branching bile pathways inside the liver. Gallbladder stones are often just the visible tip of a much larger problem.

How the Flush Works

The liver flush uses a specific sequence of substances to:

Dilate the bile ducts — Epsom salts (magnesium sulfate) relax and expand the smooth muscle tissue surrounding the bile ducts
Trigger a massive bile release — Olive oil (a large fat load) signals the gallbladder and liver to contract powerfully, ejecting bile
Lubricate the passage — The oil provides lubrication for stones to move through dilated ducts
Prevent spasm — The timing prevents the painful spasm that can occur when stones lodge in ducts

The combination of dilated ducts, powerful contraction, and lubrication allows stones to pass that would otherwise remain stuck or cause blockage.

The "Soap Stones" Controversy

Critics claim the green "stones" people expel are just saponified olive oil — soap made when oil, bile, and digestive enzymes combine. Some studies have analyzed expelled material and found it contains no cholesterol or calcium — components of real gallstones.

Here's the nuance: both things can be true. Some expelled material may be saponified oil. Some is clearly not — people have expelled stones with calcified shells that sink in water and contain cholesterol on analysis. Many people expel stones after fasts when no oil was consumed.

More importantly: regardless of what the expelled material technically is, the process clearly evacuates the biliary system. People report dramatic improvements in digestion, energy, and symptoms that Western medicine associates with bile pathology. The mechanism appears to work even if we argue about the exact nature of what's expelled.

Who Should Consider This Protocol

The liver flush is appropriate for people experiencing:

Digestive symptoms:

Bloating after eating fats
Nausea when eating rich foods
Pale or clay-colored stools (inadequate bile)
Floating stools (poor fat digestion)
Right-side discomfort under the ribs
Bitter taste in mouth, especially mornings

Systemic symptoms that suggest liver congestion:

Chemical sensitivity
Alcohol intolerance
Medication sensitivity
Hormonal imbalances
Chronic skin issues (liver spots, rashes, acne)
Chronic headaches, especially migraines with visual aura

Known conditions:

Diagnosed gallstones (with important caveats — see contraindications)
Fatty liver disease
Chronic constipation despite adequate fiber
History of hepatitis or liver stress

The flush is also used preventatively by practitioners who believe periodic biliary evacuation prevents stone accumulation — similar to how oil changes prevent engine sludge.

Who Should NOT Do This Protocol

Absolute contraindications:

Acute gallbladder attack in progress — You need medical attention, not a flush
Large gallstones (over 2cm) confirmed on imaging — These can lodge in the common bile duct, creating a medical emergency
Bile duct obstruction — If bile flow is already blocked, forcing more through is dangerous
Pregnancy — The intensity of the protocol and the oil/salt load is inappropriate
Active liver disease (acute hepatitis, cirrhosis in acute phase) — The liver cannot handle the load
Inflammatory bowel disease in flare — The Epsom salts will exacerbate
Kidney disease — Magnesium processing is impaired

Relative contraindications (proceed with caution, ideally with practitioner guidance):

Small-to-medium gallstones — The flush may pass them, but there's risk of duct obstruction
History of pancreatitis — Bile duct issues can trigger pancreatic inflammation
Currently taking medications metabolized by the liver — Consult your doctor
Diabetes — Blood sugar management during the fast requires attention
Weak constitution or chronic illness — The flush is depleting; you need reserves

Critical safety note: If you have diagnosed gallstones, get an ultrasound to assess size and location before attempting a flush. A stone larger than the diameter of the common bile duct (normally 6-8mm) can become lodged, requiring emergency surgery. This is rare but serious.

The Preparation Week: What Most People Skip

This is where success or failure is determined. The flush itself is one day. Preparation takes a week.

Why Preparation Matters

The preparation week does several things:

Softens stones — Malic acid (from apple juice or supplement) softens cholesterol deposits, making them easier to pass
Increases bile production — The body ramps up bile output when it anticipates fat
Clears the colon — You need a clear pathway for expelled material to exit
Reduces stone size — Some practitioners believe stones actually shrink during preparation

Skipping preparation increases the risk of:

Stones becoming lodged in ducts
Incomplete evacuation
More severe reactions
Stones that don't pass at all

The Standard 6-Day Preparation

Days 1-6:

Apple juice or malic acid:

Drink 32 oz (1 liter) of apple juice daily, spread throughout the day
OR take 1,500-2,000mg of malic acid in capsule form daily
Apple juice should be organic, unfiltered (cloudy) if possible
Organic Apple Juice options are available at most grocery stores

Diet:

Eat normally but avoid fried foods, heavy fats, and overeating
Keep meals lighter than usual
Avoid eating after 6-7 PM to give the liver rest time
Stay well hydrated with water in addition to apple juice

Additional support (optional but recommended):

Castor oil packs over the liver area 3-4 times during the week
Bitter herbs before meals to stimulate bile
Light exercise to promote lymphatic flow
Reduce caffeine and alcohol (ideally eliminate)

Colon preparation:

Ensure you're having at least one bowel movement daily
Consider a colonic or water enema on Day 5 or 6 to clear the path
If constipated, address this before attempting the flush

Day 6 — The Day Before the Flush

Continue apple juice through midday. Eat a light lunch — no fat at all. Good options:

Oatmeal with fruit
Steamed vegetables with rice
Vegetable soup (no oil)
Plain toast with honey

No food after 2 PM. This is non-negotiable. You need 8+ hours of fasting before the oil dose for maximum bile release.

The Flush Day: Hour-by-Hour Protocol

Gather your supplies:

Essential:

Epsom salts — 4 tablespoons (60g)
Extra virgin olive oil — 1/2 cup (120ml) — use high-quality oil
Fresh grapefruit or lemon juice — enough to make 2/3 cup (160ml) when squeezed
Jar with lid for mixing oil and citrus
Straw (for drinking the oil mixture)

Helpful:

Timer or alarm
Hot water bottle
Book or quiet activity for waiting
Bathroom supplies ready

The Schedule

2:00 PM — Last food (should have been lunch, no fat)

6:00 PM — First Epsom Salt Dose

Mix 4 tablespoons Epsom salts in 24 oz (3 cups/720ml) of water. This makes four servings.

Drink 3/4 cup (6 oz/180ml) of the mixture.

Taste is unpleasant. Strategies:

Add a small amount of citrus juice
Use a straw to bypass taste buds
Follow immediately with a sip of plain water
Hold your nose

The Epsom salts are beginning to relax your bile ducts.

8:00 PM — Second Epsom Salt Dose

Drink another 3/4 cup of the Epsom salt mixture.

You may start feeling intestinal movement. Stay near a bathroom.

Prepare the oil mixture so it's ready: combine 1/2 cup olive oil with 2/3 cup fresh grapefruit (or lemon) juice in a jar.

9:30 PM — Prepare for Bed

Visit the bathroom. Get completely ready for bed — teeth brushed, pajamas on, bed prepared. You want to be horizontal within minutes of drinking the oil.

10:00 PM — The Oil Dose

This is the main event.

Shake the oil/citrus mixture vigorously until emulsified
Stand by your bed
Drink the entire mixture within 5 minutes (use a straw if helpful)
Immediately lie down flat on your back — this is critical
Place your right hand over your liver area (right side, under ribs)
Stay completely still for at least 20 minutes

What you might feel:

Stones moving through the ducts (rolling sensations, painless in most cases)
Nausea (breathe through it, don't get up)
Urgent need to use the bathroom (resist if possible for the first 20 minutes)
Nothing at all (also normal)

If you must use the bathroom, do so, then return to lying flat.

Sleep: Try to sleep. Many people sleep poorly due to intestinal activity. Lying on your right side after the initial 20 minutes may help with stone passage. Keep a bucket nearby if you feel nauseous.

The Morning After

6:00 AM — Third Epsom Salt Dose

Upon waking (but not before 6 AM), drink the third 3/4 cup of Epsom salt mixture.

Rest if you're tired. Bowel movements will begin soon.

8:00 AM — Fourth Epsom Salt Dose

Drink the final 3/4 cup of Epsom salt mixture.

10:00 AM — First Food

Start with fresh fruit juice. Wait 30 minutes, then eat light: fruit, small portions.

Remainder of the day:

Eat light meals (soups, vegetables, fruits)
Rest as needed
Stay hydrated
Expect multiple watery bowel movements throughout the day

What to Expect: The Elimination

This is where it gets real. Let's talk about what you'll see.

The Bowel Movements

You will have multiple, watery bowel movements starting typically between midnight and 8 AM the next morning, continuing through the day.

In these movements you may see:

Green stones — The most common finding. Ranging from pea-sized to golf ball-sized. They float (due to cholesterol content). Color is from bile. These are what proponents call "liver stones" or "gallstones."

Brown/tan stones — Often older, more calcified material. May sink. More likely to be actual gallstones similar to what surgery removes.

White or cream-colored stones — May contain more calcium. Considered by some to be older deposits.

Chaff — Small, rice-like particles. Considered to be smaller stones or debris.

Bile sludge — Dark green, tarry material. This is concentrated, stagnant bile that was stored in the system.

Foam — Green or yellow foam is bile mixed with the oil emulsion.

Counting Your Stones

Many practitioners recommend collecting and counting stones. Method:

Place a colander in the toilet (or use a collection container)
After each movement, transfer contents to a bowl of water
Stones float; fecal matter sinks
Count and photograph if you want records

Typical first flush yields: 100-500 small stones, sometimes larger ones. Later flushes typically yield less, eventually little to nothing.

What's Normal vs. Concerning

Normal:

Nausea that resolves by morning
Multiple watery movements
Fatigue for 1-2 days
Temporary loose stools for 2-3 days
Sensation of "lightness" in the liver area

Seek medical attention if:

Severe, unrelenting pain (especially upper right quadrant)
Jaundice (yellowing of skin or eyes)
Fever with chills
Inability to keep anything down for over 24 hours
Signs of duct obstruction (pain + pale stools + dark urine)

These complications are rare with proper preparation and in the absence of large stones, but they are possible. A stone lodging in the common bile duct is a medical emergency.

Post-Flush Care

The flush itself is depleting. Your body has expelled significant material and your digestive system has been through an intense experience.

Days 1-3 Post-Flush

Diet:

Light, easily digestible foods
Soups, steamed vegetables, fruits
Avoid fried foods, heavy fats, alcohol, caffeine
Eat smaller portions than normal
Include bitter foods (arugula, radicchio, dandelion greens) to stimulate bile

Support:

Rest as needed
Gentle movement (walking, stretching)
Liver-supportive herbs: milk thistle, dandelion root, artichoke
Stay well hydrated

The 5-Day Colonic Protocol

Moritz strongly recommended colon cleansing after each flush. His reasoning: stones released from the liver can lodge in the colon, where they release toxins and potentially reabsorb.

Options:

Professional colonic irrigation (Day 1-3 post-flush)
Coffee enema series (daily for 3-5 days)
At-home enema series

This step is often skipped but significantly improves outcomes and reduces post-flush symptoms.

How Many Flushes? The Series Approach

One flush is not typically sufficient. Moritz recommended continuing flushes until no more stones come out — usually 6-12 flushes for most people, sometimes more for severe cases.

The Recommended Schedule

Wait 2-4 weeks between flushes (liver needs recovery time)
Continue until two consecutive flushes produce no stones
Expect the first few flushes to yield the most material
Maintenance: After clearing, some practitioners do 1-2 flushes annually as prevention

What Improves With Each Flush

People who complete a series of flushes typically report:

Digestive:

Dramatically improved fat digestion
Elimination of bloating
Regular, complete bowel movements
Resolution of nausea with fatty foods
Food sensitivities reducing or disappearing

Energy and mood:

Significant energy improvement
Mental clarity
Improved mood (less irritability, depression lifting)
Better sleep

Physical:

Chronic pain patterns resolving
Skin clearing
Liver spots fading
Allergies improving
Hormonal balance improving

Lab markers:

Liver enzymes normalizing
Cholesterol patterns improving
Inflammatory markers decreasing

These improvements are typically cumulative — each flush builds on the last.

Troubleshooting Common Problems

Nausea During the Flush

Nausea when drinking the oil is common. Strategies:

Breathe deeply before and during
Drink through a straw
Make sure the mixture is well-emulsified (shake vigorously)
Ginger tea before the oil dose
Stay lying down — nausea often worsens if you get up

If you vomit the oil (rare), the flush is compromised. Rest and try again in 2-3 weeks with better preparation.

No Stones Come Out

Possible causes:

Insufficient preparation (didn't drink enough apple juice/malic acid)
You don't have significant stones (good news)
Stones are too large or calcified to pass (may need imaging and reconsideration)
The ducts didn't dilate adequately (try increasing Epsom salt dose slightly next time)

Try again in 2-4 weeks with better preparation. If multiple flushes yield nothing and you still have symptoms, seek practitioner guidance.

Severe Cramping

Some cramping is normal — the bile ducts are contracting. Severe, unrelenting cramping may indicate:

A stone lodged in a duct
Gallbladder inflammation
Insufficient duct dilation

If cramping is severe and doesn't resolve within an hour, or if it's accompanied by fever, seek medical attention.

Incomplete Feeling

If you feel like stones were mobilized but didn't pass, options:

Continue the Epsom salts for one additional dose
Do a coffee enema to stimulate further release
Rest and wait — sometimes stones pass over the following 24-48 hours
Plan another flush in 2-3 weeks

Enhancing the Protocol

Once you're comfortable with the basic protocol, these additions can improve results:

Pre-Flush Enhancements

Phosphoric acid supplementation: Some practitioners add phosphoric acid drops during the preparation week (in addition to apple juice). Believed to further dissolve calcium in stones.

Extended preparation: For significant stone load or first-time flushers, extend preparation to 2 weeks.

Gold Coin Grass (Chinese Bitters): Traditional Chinese herb specifically for dissolving gallstones. Take for 2-4 weeks before flushing.

During the Flush

Grapefruit vs. lemon: Grapefruit is traditional and believed to be more effective. Lemon works as substitute. Some practitioners combine both.

Oil quality matters: Use the best olive oil you can find. Some practitioners prefer other oils (macadamia, walnut) for specific purposes.

Ornithine supplementation: Some versions of the protocol include 4-8 ornithine capsules with the oil dose to promote sleep. Optional.

Post-Flush

Liver support supplements:

Milk thistle — 140-420mg silymarin daily
NAC — 600-1200mg daily
Dandelion root tea — 2-3 cups daily

Digestive enzymes: Your digestive system will be resetting. Ox bile supplements with fatty meals can help while your liver/gallbladder recover their rhythm.

Integration With Other Protocols

The liver flush doesn't happen in isolation. Here's how it fits with other detox work:

The Proper Sequence

As detailed in our Complete Guide to Liver Detox, liver cleansing comes LAST in the detox sequence — after gut, kidneys, and lymph are addressed.

Do NOT do a liver flush if:

You're constipated (gut must be moving)
You haven't addressed parasites (they can block bile ducts)
Your kidney function is compromised (can't process Epsom salt magnesium)

Recommended sequence:

Gut detox — 4-8 weeks
Kidney/lymph support — 2-4 weeks
Gentle liver support — 2-4 weeks
Liver flush series — as many as needed

Combining With Coffee Enemas

Coffee enemas and liver flushes work synergistically but serve different purposes:

Coffee enemas: Support ongoing liver detox through increased glutathione production and bile flow. Can be done frequently.
Liver flush: Evacuates the biliary system of accumulated deposits. Done periodically.

Many practitioners use coffee enemas during the preparation week and for 3-5 days after each flush to support processing and elimination.

Combining With Castor Oil Packs

Castor oil liver packs during the preparation week soften the liver area, promote lymphatic drainage, and support the overall cleansing process. Use 3-4 times during the 6-day preparation.

The Debate: Real Stones or Saponified Oil?

This controversy deserves direct address.

The skeptic position: Laboratory analysis of expelled "stones" often shows they contain no cholesterol or calcium — components of real gallstones. They're composed of fatty acids and bile acids — saponification products (soap). Therefore, the flush is producing artifacts, not removing actual pathology.

The proponent position:

People have expelled calcified stones that DO contain cholesterol and calcium
People have expelled stones during water fasts with no oil consumption
Ultrasounds show gallstones before the flush and no stones after
Clinical improvements (confirmed by lab work) suggest real physiological change
Even if some material is saponified oil, the process clearly evacuates stagnant bile

A balanced view: The mechanism of the flush likely does both things: it evacuates real deposits (intrahepatic stones, bile sludge, small gallstones) AND creates some saponified material as the oil, bile, and enzymes combine. The clinical improvements reported by thousands of people suggest the process is doing something real, even if the exact nature of all expelled material is debated.

For most people doing the flush, the relevant question isn't "is this a real stone?" but "do I feel better and are my symptoms improving?" The answer, repeatedly, is yes.

Summary: The Protocol at a Glance

2:00 PM — Last food (light, no fat)
6:00 PM — Epsom salt dose 1
8:00 PM — Epsom salt dose 2
10:00 PM — Olive oil + citrus mixture, lie down immediately
Sleep on right side if possible

Next Morning:

6:00 AM — Epsom salt dose 3
8:00 AM — Epsom salt dose 4
10:00 AM — First food (light)
Observe bowel movements, count stones if desired

Post-Flush:

Light eating for 2-3 days
Coffee enemas or colonic recommended
Liver support supplements
Rest as needed

Repeat:

Wait 2-4 weeks
Continue until two consecutive flushes produce no stones
Maintenance: 1-2 annually

Final Thoughts

The liver flush is not casual wellness. It's an intensive protocol that has helped thousands of people resolve chronic digestive issues, avoid gallbladder surgery, and restore energy and vitality. It's also uncomfortable, requires real commitment, and carries risks if done incorrectly or by people with contraindications.

If you decide to do it:

Prepare properly — don't skip the apple juice week
Verify you don't have large stones via ultrasound if concerned
Have support available (someone who knows what you're doing)
Plan for a restful day after
Be willing to do the series — one flush is rarely sufficient

The liver never stops working. For most of us, decades of processed foods, environmental toxins, hormonal fluctuations, and pharmaceutical loads have left deposits in our biliary systems that slow us down in ways we've normalized. The flush offers a way to clear that backlog — dramatically, quickly, and at home.

Is it for everyone? No. Is it powerful for those who need it? Absolutely.
