Garlic has many health benefits. According to the University of Maryland Medical Center, consuming garlic may lower your blood pressure, strengthen your immune system and ward off common colds. Aside from containing vitamin C, magnesium, selenium and vitamin B6, garlic also contains sulfuric compounds which your body cannot break down, so they are released through sweating and breathing. They leave you with a bad taste in your mouth and garlic breath.
Avoid eating garlic completely if you don't want to deal with the bad breath and lingering aftertaste. Take garlic supplements if you consume garlic for its health benefits. Supplements will not leave a taste in your mouth or cause bad breath.
Chop up at least one fresh sprig of parsley and add it to your garlic-rich meal before consumption. Parsley alleviates garlic breath. Eating a fresh sprig of parsley after your meal will also work, but is not as effective as consuming the parsley and garlic together.
Chew cardamom seed to camouflage the smell and taste of garlic. Cardamom has a distinctive, almost medicinal-like scent which is more acceptable than that of garlic.
Drink a glass of full-fat milk with your garlic-rich meal. According to The Telegraph, drinking 200 ml of full-fat milk suppresses the garlic's sulfurous properties.
Floss your teeth and brush them thoroughly with toothpaste. Brush your tongue as well. Use mouthwash and chew a piece of sugarless gum. These masking methods will work for approximately two to three hours. The garlic taste and breath can last up to 72 hours.
