None of the listed ingredients in this tea is a source of caffeine. The blend contains pine cone, chamomile, oregano, bergenia leaf and blackcurrant leaf, and it contains no Camellia sinensis tea leaves and no coffee. For most people, that makes it a sensible choice when you want a warm, aromatic drink in the evening without the stimulant effect of coffee or black/green tea.
This is exactly the situation the product is positioned for in the description: it is chosen as a non-coffee evening drink, for a peaceful pause after work, or for moments when you want to slow down before sleep. Chamomile and oregano are traditionally used in herbal infusions for a calmer mood, and the overall profile is not intended to be energising.
That said, no caffeine does not automatically mean sleep-inducing. Herbal teas can affect people differently. If you are sensitive to any botanical, or if you take medication and are unsure about interactions, check with a specialist before making it a regular part of your evening routine. Also, wait for the tea to cool to a comfortable drinking temperature rather than drinking it extremely hot, especially if you plan to relax before bed.
If you usually drink several cups in the evening, remember that any warm liquid before bedtime may increase night-time trips to the bathroom. A single cup about an hour before bed is often enough to enjoy the flavour and aroma without disrupting sleep.
