Potential Ginkgo Biloba Side Effects, Adverse Reactions And Contraindications

Ginkgo biloba is an herb made from the leaves of the ginkgo tree. With a long history in Chinese medicine, this great herb has many health benefits.

It contains important antioxidants, terpenoids and flavonoids, that have been found to increase blood circulation throughout the body and protect cells from damage, especially in the brain. It has been used to threat multiple conditions of the brain, for example Alzheimer‘s disease, as well as improve the immune system and fight off infections.

There are unfortunately some potential ginkgo biloba side effects, adverse reactions and contraindications which you should be aware of.

Allergic reaction

It is possible that ginkgo biloba will cause an allergic reaction. This might mean you experience rashes and itching. If you develop more severe symptoms of swelling or difficulty in breathing, it is advised that you contact your healthcare provider immediately. If you know you are allergic to poison ivy, poison oak, poison sumac, mango rind or cashew shell oil, it can increase your risk of being allergic to ginkgo biloba as well.

Bleeding problems

Because of the effectiveness of ginkgo biloba in increasing blood circulation, the negative side effect to it is that it can increase your risk of bleeding and even cause bruising. This is especially true if you use any medication, for example blood thinning medication, or you are about to undergo a surgery. There are also herbs that can increase your risk of bleeding if used together with ginkgo biloba. These include danshen, devil’s claw, garlic, ginger, horse chestnut, red clover and saw palmetto.

Diabetes and cholesterol

Potential ginkgo biloba side effects may also include risk to people with diabetes and high blood pressure. The herb has been found to both raise and lower blood sugar levels and thus there is not enough evidence to conclude it is safe to use if you are using other medications or supplements for diabetes. The same has also been found regarding cholesterol levels, and thus it is advised to refrain from using the herb if you are taking cholesterol medications or supplements.

Seizures

According to WebMD, there is some evidence that people with history of seizures, for instance epilepsy, should not use the herb supplement. Ginkgo biloba side effects might include the risk of causing further seizures.

Pregnancy and breastfeeding

Because of the abovementioned ginkgo biloba side effects of increased bleeding and possibility of seizures, it is not advised that you use the supplement during pregnancy. You should also refrain from use during breastfeeding because there is no conclusive evidence suggesting it is safe for the child.

Cancer

There have been some recent studies that have linked increased risk of certain types of cancer to ginkgo biloba side effects. A recent study was reported in a New York Times article that had found ginkgo biloba extract increasing the risk of certain types of liver and thyroid cancers, as well as nasal tumors. The 2013 article reported that the study had only been done on animals but that the research reports caused some concern regarding potential ginkgo biloba side effects.

Do not consume ginkgo biloba seeds or use it fresh

The most severe ginkgo biloba side effects can occur if you use the fresh produce or the seeds of this herb in any form. Consuming ginkgo biloba seeds, for instance dried or roasted, can cause seizures, vomiting, loss of consciousness and even lead to death. If you suspect accidental consumption of ginkgo biloba seeds or experience any of the above symptoms, you should consult your healthcare professional immediately.
