Safety & Precautions

Lemon balm is generally well-tolerated, though it may cause mild digestive upset or drowsiness in some people, particularly at higher doses. Because of its traditional effect on thyroid activity noted in some sources, those with hypothyroidism or thyroid conditions should consult a healthcare provider before regular use. It may increase drowsiness when combined with sedative medications, so caution is advised in that combination. Pregnant and breastfeeding individuals should consult a healthcare provider before use, as robust safety data is limited, though culinary tea-strength amounts are generally considered lower risk. Lemon balm is generally considered non-toxic to pets in small amounts, but concentrated tinctures or extracts should be avoided without veterinary guidance.

Q&A

Does lemon balm taste bitter?

No, lemon balm has a bright, lemony, slightly minty flavor rather than a bitter one, which makes it one of the more approachable and pleasant-tasting calming herbs. Its fresh, citrusy taste is part of why it’s popular in both hot and iced tea.

Lemon balm pairs well with other mild herbs like chamomile or mint, which complement its light, lemony character.

Can lemon balm be used daily?

Yes, lemon balm is commonly used daily, particularly as a calming tea or as part of an ongoing routine to support mood and digestive comfort. Many traditional and modern wellness routines include lemon balm tea regularly without issue.

Because of its potential effect on thyroid function noted in some sources, those with thyroid conditions using lemon balm daily should check in with a healthcare provider periodically.

Is fresh or dried lemon balm better?

Both fresh and dried lemon balm are used traditionally, though fresh leaf tends to have a brighter, more pronounced lemony aroma, while dried leaf is more practical for year-round tea and tincture-making. Fresh lemon balm is often used directly from the garden when in season.

Dried lemon balm loses some of its volatile oil content over time, so using it within a reasonable window after drying helps preserve its characteristic scent and flavor.

Can lemon balm be applied directly to cold sores?

Yes, lemon balm has a long traditional history of topical use for cold sores, typically applied as a salve, cream, or diluted extract directly to the affected area. Many people apply it at the first sign of a cold sore developing.

A patch test on a small area of skin first is a reasonable precaution, especially for those with sensitive skin or who haven’t used lemon balm topically before.

How should lemon balm leaf be stored?

Dried lemon balm leaf should be stored in an airtight container away from light, heat, and moisture, where it typically retains potency for about a year, though its lemony aroma is best within the first several months. Fresh lemon balm should be refrigerated and used within a week or so.

Lemon balm tincture stores well for several years when kept in a dark glass bottle away from direct light and heat.
