世界各地的飲食習慣大多包含大蒜，地中海、中國和中東等地也都如是。大蒜自古以來都有食用和藥用價值。
近年已有多項關於大蒜的研究，發現大蒜能改善心臟病、血壓高、膽固醇高和癌症等等。據美國國立衛生研究院的研究顯示，大蒜也能有效治療糖尿病、花粉症、感冒和流感等不適。
著名草藥學家James A. Duke博士稱大蒜為“能用於任何心臟或循環系統疾病的主要植物。”
大蒜對保護心血管承擔起三個重要作用：它可以降低膽固醇和三酯甘油脂，降血壓和防止動脈粥樣硬化（導致動脈血管閉塞）。
經發酵的老蒜提取物（Aged Garlic Extract）常用於治療慢性冠狀動脈疾病和緩慢鈣化（導致動脈硬化）等問題。一項關於停經後婦女心血管疾病的研究顯示，服用老蒜提取物配合適量運動，對調節低密度膽固醇(俗稱壞膽固醇)有正面作用。
而最近一項為期12週的研究顯示，每日服兩粒老蒜提取物（總共480毫克），能顯著降低收縮壓(或稱爲上壓)數值。
The Garlic bulb and Heart Health
A staple in diets around the world, from the Mediterranean to China and the Middle East, garlic has also been used medicinally since ancient times.
Garlic has been studied for heart disease, blood pressure, cholesterol, and cancer. According to the National Institutes of Health, it’s also been used to treat diabetes, hay fever, colds, and flu.
Herbalist James A. Duke, PhD, calls garlic “our premier plant for virtually any heart or circulatory condition.”
Garlic’s cardiovascular (CV) protection works like threefold armor: it cuts cholesterol and triglycerides, lowers blood pressure, and protects against atherosclerosis (clogged arteries).
Aged garlic extract (AGE) has been used to treat patients with chronic coronary artery disease and to slow calcification (which leads to hardened arteries). In a study of CV disease in postmenopausal women, a program of AGE combined with exercise had a major impact on LDL (bad) cholesterol.
A recent 12-week study showed that two capsules daily (480 mg total) significantly reduced participants’ systolic (top number) blood pressure.
