Garlic contains several biologically active sulfur compounds. Allicin is particularly interesting because it has demonstrated antimicrobial activity in laboratory studies.
Garlic has also been studied for possible effects on cardiovascular health, including blood pressure and cholesterol. Some research suggests that certain garlic preparations may have modest effects, although results vary depending on the preparation and the individual.
This makes garlic an interesting functional food, but not a replacement for medical treatment.
Raw Garlic vs. Cooked Garlic
Raw garlic has a much stronger flavor and aroma. Crushing it allows allicin-related compounds to form, while heat can alter some of these compounds.
If raw garlic causes stomach discomfort, cooked garlic may be a much more comfortable option.
Try adding garlic to:
- Soups and stews
- Roasted vegetables
- Beans and lentils
- Chicken and fish
- Tomato sauces
- Salad dressings
- Homemade marinades
- Whole-grain dishes
Can Garlic Treat an Infection?
Garlic should not be relied upon to treat an infection.
A sore throat, urinary infection, skin infection, dental infection, pneumonia, or other bacterial illness may require proper diagnosis and, when appropriate, prescription antibiotics. Delaying treatment in favor of a home remedy can allow an infection to become more serious.
Garlic can be part of a healthy diet, but it should be viewed as food rather than medicine.
Who Should Be Careful With Garlic?
Large amounts of raw garlic may cause heartburn, nausea, abdominal discomfort, bloating, or diarrhea in some people.
Garlic may also interact with certain medications, particularly medicines that affect blood clotting. Anyone taking prescription medication regularly should check with a doctor or pharmacist before using concentrated garlic preparations or supplements.
The simplest approach is often the best one: enjoy fresh garlic regularly as part of balanced meals, appreciate its distinctive flavor and naturally occurring compounds, and seek appropriate medical care whenever you have symptoms of an infection.
