Introduction
To improve halitosis, one may drink lemon water, osmanthus flower tea, honeysuckle tea, mint tea, or lophatherum grass tea—these beverages may help alleviate oral odor through their regulatory effects on the body and are intended solely for daily health maintenance. If halitosis persists or recurs over a prolonged period without improvement, prompt medical evaluation is essential to identify the underlying cause. 1. Lemon Water: Lemon water can stimulate salivary secretion and relieve dry mouth.

Improving halitosis (bad breath) can be supported by drinking lemon water, osmanthus flower tea, honeysuckle tea, mint tea, or lohansia (light bamboo leaf) tea. These beverages may help alleviate oral odor through their regulatory effects on the body and serve as part of daily health maintenance. However, persistent or recurrent halitosis that fails to improve over time warrants prompt medical evaluation to identify underlying causes.

1. Lemon Water: Lemon water stimulates salivary secretion, alleviates oral dryness, and dilutes odor-causing substances in the mouth. Its refreshing citrus aroma helps neutralize unpleasant breath—making it suitable for individuals with halitosis caused by xerostomia (dry mouth) or dehydration. It may be consumed in moderation as part of daily routine.

2. Osmanthus Flower Tea: Osmanthus flower tea possesses a delicate, fragrant aroma and helps soothe gastric heat accumulation. It may provide auxiliary relief for halitosis resulting from excessive heat in the spleen and stomach. Being relatively mild in nature, it is generally safe for most people to consume regularly as a substitute for plain water.

3. Honeysuckle Tea: Honeysuckle tea helps clear internal heat and relieve halitosis triggered by gingival inflammation (“excess fire” in gums) or pharyngeal dryness and heat. It is particularly suitable for individuals with pronounced internal heat; however, prolonged or excessive consumption should be avoided to prevent impairment of spleen and stomach function.

4. Mint Tea: Mint tea offers an immediate cooling sensation and helps freshen the mouth while reducing oral heat, thereby rapidly suppressing unpleasant odors. It is especially beneficial for halitosis caused by “heatiness” (excess internal heat); consuming a small amount after meals may help mitigate residual food-related odors.

5. Lohansia (Light Bamboo Leaf) Tea: Lohansia tea clears deficient heat from the body and improves bitter taste and halitosis caused by internal heat steaming upward. It also aids hydration and reduces systemic heat—providing supportive regulation for oral odor associated with “heatiness.”

These beverages offer only adjunctive, symptomatic relief and cannot replace medical treatment. For optimal oral hygiene, brush teeth thoroughly twice daily, clean the tongue regularly, limit intake of strongly flavored or pungent foods, and maintain adequate hydration—all of which help reduce the recurrence of halitosis.
