Clinically, the exact duration of discontinuation of Ginkgo Biloba varies, ranging from about 1 to 3 months. If a serious adverse reaction occurs while taking the medicine, the medicine should be stopped immediately. Ginkgo biloba has the effect of activating blood circulation and removing blood stasis (promoting blood circulation and eliminating blood stasis in the body) and opening up collaterals. It can be used for treating chest paralysis (chest pain), heart pain, stroke, hemiplegia (inability to move one side of the limbs), strong tongue and strong speech caused by blood stasis and obstruction of collaterals; and stable angina of coronary heart disease and cerebral infarction with the above mentioned symptoms. When treating the above diseases, Ginkgo biloba usually needs to be taken for about 1 to 3 months. A very small number of patients may experience gastrointestinal discomfort, headache, lower blood pressure, allergic reactions and other phenomena, which generally do not require special treatment to relieve. However, if more serious adverse reactions occur when taking ginkgo biloba, the drug should be discontinued. This medication is not recommended for people who are allergic to ginkgo. The drug is a prescription drug and should be taken strictly on medical advice.
