Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Garlic bulb (Allium sativum) has a long history of use in traditional medicine for cardiovascular health, including the management of arteriosclerosis (hardening of the arteries). Modern scientific studies have explored garlic's effects on various cardiovascular risk factors, such as cholesterol levels, blood pressure, and platelet aggregation, which are relevant to arteriosclerosis. Several meta-analyses and randomized controlled trials suggest that garlic supplementation can modestly reduce total and LDL cholesterol, as well as lower blood pressure in hypertensive individuals. These effects are thought to be due to garlic's sulfur-containing compounds, especially allicin, which may improve endothelial function and exert anti-inflammatory and antioxidant effects on vascular tissues.

However, while these findings provide a rationale for garlic's potential in supporting cardiovascular health and possibly slowing the progression of arteriosclerosis, the evidence is not uniformly strong or conclusive. The magnitude of benefit is generally modest, and not all studies have demonstrated statistically significant improvements in atherosclerotic outcomes or direct reversal of arterial plaque. Additionally, issues such as dosage, preparation (fresh versus aged or powdered garlic), and study quality contribute to variability in outcomes.

In summary, garlic bulb has scientific support for its cardiovascular benefits, particularly in improving some risk factors related to arteriosclerosis, but the evidence specifically for treating or reversing arteriosclerosis itself is moderate (rated 3/5). It is best considered as an adjunct to, rather than a replacement for, established medical therapies.
