Arm && Interventions

Group	Intervention	Description
placebo	Placebo	As a food ingredient that does not affect blood pressure and is harmless to the human body, it is made almost identical in weight and appearance to garlic extract.
Garlic extracts	Garlic extracts	Take 450mg of Garlic extracts(Food Item Making Report Product Name: Vegetable Extract Powder No. 1905, Item Report No.: 202004980275)

Primary Outcome Measures

Name	Time	Method
Change of peak systolic blood flow velocity in the internal carotid arteries	Change of peak systolic blood flow velocity before and after 60 minutes garlic extract intake basis in the experimental group	Doppler ultrasonography is used for measurement.
Change of peak systolic blood flow velocity in the common carotid arteries	Change of peak systolic blood flow velocity before and after 60 minutes garlic extract intake basis in the experimental group	Doppler ultrasonography is used for measurement.
Change of end-diastolic blood flow velocity in the internal carotid arteries	Change of end-diastolic blood flow velocity before and after 60 minutes garlic extract intake basis in the experimental group	Doppler ultrasonography is used for measurement.
Change of end-diastolic blood flow velocity in the common carotid arteries	Change of end-diastolic blood flow velocity before and after 60 minutes garlic extract intake basis in the experimental group	Doppler ultrasonography is used for measurement.
Change of diastolic and systolic blood pressure	Change of diastolic and systolic blood pressure before and after 60 minutes garlic extract intake basis in the experimental group	The blood pressure device is measured by IntelliVue MP50® from Philips. When measuring blood pressure, the study subjects should sit comfortably for at least 5 minutes and then take the measurements. The unit is mmHg and is expressed as an integer.
