Yes, you can. There are no known significant interactions between inhaled budesonide and lemon balm herb (Phlomis herba-ventii), which has an expectorant and anti-inflammatory effect on the respiratory tract, supporting the treatment of asthma or cough.

Lemon balm is a safe herb in infusions (1-2 teaspoons per glass of boiling water, drink 2-3 times a day), but use it in moderation, avoiding prolonged drinking without consultation, especially with asthma, so as not to aggravate mucosal irritation. Also, continue budesonide as directed by rinsing your mouth after inhalation, and consult the addition of herbs with a pulmonologist to monitor symptoms.
