Garlic Mouthwash Shows Strong Germ-Fighting Power
A new study found that mouthwash made from garlic can fight germs almost as well as a common dental mouthwash called chlorhexidine.
The researchers looked at five studies and found that garlic mouthwash can reduce bacteria in the mouth, but it might cause a stronger burning feeling.
Garlic is known for its natural germ-fighting properties and is used in many health products.
However, more research is needed to confirm if garlic mouthwash can be used as a regular alternative to chlorhexidine.
Garlic is mostly grown and eaten in China, and its market is growing because people want more natural wellness products.
Garlic extract mouthwash shows comparable antimicrobial effects to chlorhexidine, according to a systematic review.
Garlic mouthwash may cause more discomfort but stays active in the mouth longer than chlorhexidine.
The study analyzed five clinical trials and found that higher-concentration garlic mouthwashes delivered similar antimicrobial results to chlorhexidine.
Garlic's side effects are generally milder than those of synthetic agents, but patient comfort and taste may influence its acceptance.
More research is needed to confirm garlic's effectiveness in real-world dental practice before it can be positioned as a mainstream alternative to chlorhexidine.
