Giloy: The 'most dangerous' Ayurvedic herb? Top hepatologist warns it can harm your liver

Giloy, also called guduchi, is one of the most popular herbs in Ayurveda. For centuries, it has been used as a natural remedy for boosting immunity, improving digestion, reducing fever, and promoting overall health. People often consume it as giloy juice, giloy powder, or in supplement form. While it has been praised as a healing plant, recent medical findings suggest that giloy may not be as safe as once believed. According to a TOI report, leading hepatologist Dr. Cyriac Abby Philips, known as The Liver Doc, has warned that giloy can cause serious liver damage in certain people. He explained that the herb may trigger immune-mediated liver injury, which can harm the body instead of healing it.

The biggest concern raised by doctors is that giloy can overstimulate the immune system. Dr. Philips explained that this immune reaction may lead the body to attack its own liver cells, causing inflammation and long-term complications. Early signs of giloy liver damage include jaundice (yellowing of skin and eyes), abdominal pain, fatigue, nausea, and dark urine. Studies and case reports from India suggest that around 200 patients have developed liver injury after consuming giloy, with some needing hospital care. While Ayurveda promotes giloy as an immunity booster, science shows that “natural” does not always mean safe.

Experts warn that certain groups of people should be especially careful with giloy. According to Dr. Philips, those with autoimmune conditions such as lupus, rheumatoid arthritis, or inflammatory bowel disease are at higher risk. People with diabetes or thyroid problems should also avoid giloy, as their conditions may worsen liver stress. In addition, anyone taking medicines that affect the liver or immune system should stay away from giloy supplements. Even small or moderate amounts may lead to giloy side effects, showing why medical advice is essential before using it.

TOI reports highlight that giloy-related liver injury is not just rare. More than 200 cases have been documented in India alone, making it a serious health issue. International health bodies also warn that herbal supplements, including Ayurveda remedies, can cause harm if not used carefully. For example, giloy liver damage has been compared to other herbs like turmeric, which are safe in small amounts but harmful when misused. Experts say patients should watch out for warning signs like fatigue, abdominal swelling, or loss of appetite if they are consuming giloy.

While Ayurveda has many benefits, it is important to remember that herbal remedies can also cause harm. Dr. Philips stresses that giloy should never be taken without medical guidance, especially for people with pre-existing health conditions. Natural supplements may interact with prescribed medicines, overstimulate the immune system, or damage the liver if used wrongly. The simple advice is: always consult a doctor before using giloy, avoid self-medicating with herbal remedies, and stop use immediately if unusual symptoms appear.
