What is Ginkgo Biloba?
Ginkgo biloba is an herbal supplement derived from the leaves of the ancient ginkgo tree, a species known as a "living fossil" due to its ancient lineage. Native to China, it has been used in traditional Chinese medicine for centuries to address various ailments, including respiratory issues, circulatory problems, and cognitive complaints. In modern contexts, standardized ginkgo leaf extracts are widely available as supplements, most notably used to support cognitive function and blood circulation, though official endorsements are lacking.
The Link Between Ginkgo and Diarrhea
Yes, ginkgo biloba can cause diarrhea. Gastrointestinal upset, including nausea, stomach pain, and diarrhea, is a known side effect for some people, although it is generally considered minor and less common than other side effects like headache. The exact mechanism for this digestive sensitivity is not fully understood, but it is believed to be related to individual sensitivities to the compounds found in the ginkgo leaf extract. It is important to distinguish this from the severe, toxic gastrointestinal effects, including intense diarrhea, seizures, and death, caused by consuming raw or roasted ginkgo nuts or seeds, which contain high concentrations of the toxin ginkgotoxin. This article focuses solely on the milder, common side effect associated with standardized leaf extracts.
Factors Increasing the Risk of Diarrhea
Several factors can contribute to experiencing diarrhea when taking ginkgo biloba:
- Higher Doses: Taking a higher dosage than recommended significantly increases the likelihood of side effects, including digestive problems. Starting with a low dose and gradually increasing it allows your body to adjust.
- Taking on an Empty Stomach: Consuming ginkgo supplements with or after a meal is a recommended strategy to minimize gastrointestinal issues like stomach upset and diarrhea.
- Individual Sensitivity: Like any herbal supplement or medication, personal tolerance varies. Some individuals have a more sensitive digestive system and are simply more prone to these side effects.
- Other Ingredients: The supplement market is not strictly regulated by the FDA, meaning that the quality and purity of products can vary. Some products may contain other ingredients or contaminants that contribute to digestive distress. Opting for supplements with third-party certifications can mitigate this risk.
How to Manage and Prevent Ginkgo-Related Diarrhea
For those who experience this side effect, several strategies can help manage or prevent it:
- Adjust Your Dosage: Try reducing your daily intake. A common starting dose in studies is 120mg per day, often split into smaller doses taken two or three times a day.
- Time Your Intake: Always take your ginkgo supplement with food to lessen the chance of stomach upset.
- Stay Hydrated: Diarrhea can lead to dehydration. Drinking plenty of water and other clear fluids is essential to replace lost electrolytes.
- Follow a Bland Diet: For a few days, try eating easy-to-digest foods that are less likely to irritate your system. A BRAT diet (Bananas, Rice, Applesauce, Toast) is a classic choice for managing diarrhea.
- Consider Probiotics: Probiotics can help restore the balance of healthy bacteria in your gut, which may be beneficial for managing diarrhea.
- Consult a Professional: If diarrhea persists or is accompanied by other symptoms, it's crucial to speak with a healthcare provider to explore potential causes and rule out serious complications.

|---|---|---|---|
| Mild Digestive | Diarrhea, constipation, nausea, upset stomach, dry mouth | Generally low | High dosage, taking on empty stomach, individual sensitivity |
| Mild Neurological | Headache, dizziness | Low | Dosage, individual sensitivity |

Other Important Considerations
Before taking any supplement, including ginkgo biloba, it is wise to consult a healthcare professional. This is especially true if you are already taking other medications. Ginkgo can interfere with blood-thinning medications like warfarin or aspirin, increasing the risk of serious bleeding. It can also interact with certain antidepressants and anti-seizure medications. Discontinuing ginkgo at least two weeks before any scheduled surgery is also a standard precaution. For further insights into supplement safety, read this guide on natural supplements.
