24 Jul Garlic: Good for Your Heart!
It may not smell like a lily, but Garlic (Allium sativum) is an edible bulb from the lily family. Fondly known to herbalists as “the stinking rose”, for centuries, there has been many traditional medicine uses for Garlic, including treatment of skin conditions, immune support, antimicrobial and, to reduce risk for cancer and heart disease. In fact, Garlic is one of the most widely studied herbal supplements for its beneficial effects on the heart.
The benefits of garlic are far ranging. Garlic contains several vitamins and minerals that support heart health, including vitamin B6, vitamin C, manganese, and selenium. But it’s the chemicals that give garlic its pungent odor that scientists believe are the source of the herb’s heart health-promoting effects. Garlic is rich in the antioxidant compounds (allicin, alliin, and ajoene) that help reduce the risk for cardiovascular disease.
Studies on garlic and the cardiovascular system typically use garlic powder, oil, or aged extracts. To date, the effects of garlic on the heart that are supported by science include:
Slows the development of atherosclerosis (building the plaques that cause narrowing of the arteries)
Reduces blood pressure
Reduces triglycerides and therefore lowers total cholesterol
The amount of active compounds supplied by garlic supplements can vary because allicin is fragile to things such as air and heat. For example, aging garlic to reduce its odor also reduces the allicin present and compromises the effectiveness of the product. Adding to your diet 1-2 cloves of fresh garlic per day may be sufficient to protect your cardio-vascular system. Easiest way to do it is to blend it with your morning shake and rip full benefits of food based nutrients. To prevent garlic smell adds cilantro or parsley to the blend, which are also powerful antioxidant herbs.
Generally safe for most adults, taking a garlic supplement can cause heartburn, upset stomach, an allergic reaction, and breath and body odor (common with raw garlic). Garlic should not be taken by persons who are preparing for surgery or who have bleeding disorders because it can impair the body’s ability to form blood clots.
