The effectiveness of herbal remedies depends on the time of their use. The vast majority of herbal teas are taken 15-30 minutes before meals: for children – 15 min, adults – 20-25 min, the elderly – 25-30 min.
Exceptions comprise emmolient, expectorant and bronchodilators; as well those that affect blood pressure and central nervous system (sedative, adaptogenic); hormone- like (excluding licorice), which are consumed 1.5 – 2 hours after a meal.
