Although the active ingredients in ginkgo biloba leaves have certain preventive effects on cardiovascular diseases, if you simply use ginkgo biloba leaves in water to drink, it does not achieve the effect of treating hypertension. Therefore, it is recommended that patients with hypertension be treated with standardized medication under the guidance of a doctor, while actively adjusting their lifestyles and diets. The main medicinal components of ginkgo biloba leaves are ginkgo flavonoids and ginkgolide, which have the function of dilating blood vessels and reducing myocardial oxygen consumption, as well as certain antioxidant activity, thus having a certain therapeutic effect on lowering blood lipids and blood pressure. However, these two ingredients need to be purified and other professional processing, and by professional doctors to guide the specific use, assessment of specific dosage, in order to achieve certain therapeutic effects. The simple use of ginkgo biloba leaves in water simply does not reach the drug dose, and therefore does not have a therapeutic effect. In addition, ginkgo biloba flavonoids and ginkgolide are insoluble in water, so drinking only through ginkgo biloba leaves in water is unable to play its drug effect, and may also produce hydrocyanic acid, causing headache, dizziness, nausea, vomiting, breathing difficulties and other toxic side effects, which endanger human health. To sum up, it is not recommended for hypertensive patients to use ginkgo biloba leaves in water on their own. They can control their blood pressure by adjusting their lifestyle and diet and taking antihypertensive drugs as prescribed by their doctors. In daily life, pay attention to low salt, low sugar and low fat diet, abstain from smoking and alcohol, avoid staying up late at night, and maintain a peaceful state of mind. At the same time, due to individual differences, different medications need to be given according to the classification and causes of hypertension. Common medications include captopril, valsartan, metoprolol, nifedipine and hydrochlorothiazide, etc. Blood pressure should be monitored regularly to keep track of the therapeutic effects of medications and changes in blood pressure in order to achieve better treatment results.
