Garlic has been used in traditional medicine for centuries, and modern research has found that some of its compounds have antimicrobial activity. One of the best-known compounds is allicin, which is produced when fresh garlic is crushed or chopped.
Can Garlic Fight Infections?
Laboratory studies have shown that compounds found in garlic can inhibit certain bacteria and other microorganisms. However, results observed in laboratory experiments don’t necessarily mean that eating garlic can treat an infection in the human body.
For this reason, garlic should be considered a food with potentially useful antimicrobial properties, rather than a replacement for medically prescribed antibiotics.
How to Include Garlic in Your Diet
Fresh garlic can easily be added to everyday meals:
- Add chopped garlic to soups and stews.
- Mix crushed garlic into vegetables or sauces.
- Add it to salad dressings.
- Use it as a seasoning for meat, beans, or grains.
Garlic is also nutritious and can be part of a balanced diet.
Don’t Replace Antibiotics With Garlic
If a doctor has prescribed antibiotics for a bacterial infection, don’t stop or replace the medication with garlic without medical advice. Untreated bacterial infections can sometimes become serious.
Garlic can complement a healthy diet, but it shouldn’t be relied upon as a treatment for a diagnosed infection.
The Bottom Line
Garlic contains compounds with antimicrobial effects demonstrated in laboratory research, but that doesn’t make garlic a substitute for antibiotics. Think of it as a flavorful, nutritious food—not a home replacement for medical treatment.
