1. Peppermint (Mentha piperita)

Mentha piperita, commonly known as peppermint, is a popular herb used in herbal decoctions to address bad breath due to its refreshing and antimicrobial properties.
When prepared as a decoction, peppermint leaves are simmered in water to release essential oils that help neutralize oral bacteria and reduce odor-causing compounds. This natural remedy is particularly effective for temporary relief of halitosis caused by mild digestive issues or poor oral hygiene. The cooling and stimulating effects of peppermint also promote saliva production, which further aids in cleansing the mouth.
While it is generally safe for most people, individuals with certain medical conditions or allergies should consult a healthcare professional before using peppermint decoctions regularly.
2. Black pepper (Piper nigrum)

Piper nigrum, commonly known as black pepper, has been traditionally used in herbal medicine for its potential benefits in improving oral health.
Herbal decoctions made from black pepper are believed to help reduce bad breath by stimulating saliva production, which naturally cleanses the mouth. The active compound piperine in black pepper may have antimicrobial properties that inhibit the growth of bacteria responsible for halitosis.

The herbal decoction of licorice root is believed to possess antimicrobial properties that can help reduce the bacterial load in the oral cavity, which is a common cause of halitosis. When prepared as a decoction, licorice root is typically simmered in water to extract its active compounds, such as glycyrrhizin and flavonoids, which may support oral health. Some studies suggest that licorice root may help soothe inflamed gums and promote a balanced oral microbiome.
