Can Gallstones Be Treated with Herbal Remedies? A Scientific Review

How do gallstones form?

Gallstones form when the balance between cholesterol, bile salts and bilirubin in bile is disturbed. Two main types exist: cholesterol stones and pigment (bilirubin) stones.

Bile stasis, cholesterol supersaturation and the growth of microscopic crystals into larger stones are the key mechanisms.

Risk factors

• Female sex and increasing age
• Pregnancy and the postpartum period
• Obesity and rapid weight loss (including after bariatric surgery)
• Family history of gallstones
• Type 2 diabetes and metabolic syndrome
• Haemolytic disorders (pigment stones)
• Prolonged fasting, total parenteral nutrition
• Certain drugs (estrogen therapy, ceftriaxone, octreotide)

Symptoms and diagnosis

The classic picture is biliary colic: sudden, cramping right-upper-quadrant pain, sometimes radiating to the back or right shoulder, usually with nausea. Fatty meals often act as a trigger.

Abdominal ultrasound is the first-line imaging test. Liver function tests and, if indicated, amylase-lipase are checked; MRCP and — in selected cases — ERCP are used when common bile duct involvement is suspected.

Silent versus symptomatic stones

Most asymptomatic (silent) gallstones can simply be observed. Guidelines do not recommend routine surgery in these patients, though surgery may be discussed in porcelain gallbladder, numerous small stones, selected long-life-expectancy diabetic patients, or when high-risk polyps coexist.

In patients who already had one biliary colic or symptoms, the risk of recurrence and complications is higher and surgery becomes an option.

Serious risks of unnecessary delay

Delaying appropriate treatment in symptomatic patients can lead to severe complications in some cases. Some of these can require intensive care and may be life-threatening.

• Acute cholecystitis
• Empyema, gangrene and perforation of the gallbladder
• Common bile duct stones and obstructive jaundice
• Acute cholangitis
• Gallstone pancreatitis
• Peritonitis and sepsis

What do herbal approaches actually show?

The 'olive-oil-and-lemon liver flush' relies on ingested oil combining with bile salts and fatty acids in the intestine to form soft greenish pellets that are then presented as 'stones'. Laboratory analyses have repeatedly shown these are not true gallstones.

There are no reliable randomised trials showing that apple cider vinegar, artichoke (Cynara scolymus), milk thistle (Silybum marianum, silymarin) or similar herbal products dissolve gallstones or make them pass safely. Some substances may increase bile flow, but this does not mean an existing stone disappears, and none is an established guideline recommendation.

Oral ursodeoxycholic acid (UDCA) as a dissolution therapy applies only to a very narrow subgroup — small, cholesterol, non-calcified stones with preserved gallbladder function. Its effect is limited, treatment is long, and stones frequently recur after stopping.

• Herbal products may interact with drugs, including anticoagulants such as warfarin
• They can delay diagnosis and needed surgery
• They can mask acute cholecystitis and worsen complications

Who is surgery considered for?

• Recurrent biliary colic or a single documented colic episode
• Previous acute cholecystitis or gallstone pancreatitis
• Common bile duct stones and obstructive jaundice
• Porcelain gallbladder, coexisting large polyp or suspected cancer
• Selected silent-stone patients where the individual risk-benefit balance favours surgery

Laparoscopic cholecystectomy

For symptomatic gallstone disease, laparoscopic cholecystectomy is the worldwide standard of care. The operation is performed through a few small abdominal incisions using a camera and instruments; the whole gallbladder is removed.

Operating time is short in most patients and hospital stay is usually one night. Most patients return to normal daily life within 1–2 weeks and to full activity within a few weeks. Rare risks include bile duct injury, bleeding, infection and bile leak; in experienced centres these risks are low.
