The manufacturer describes this as a herbal tea, not a medicine, and it is not intended to diagnose, treat, or prevent any disease. The main caution concerns eleuthero, the Siberian ginseng root in the blend: adaptogenic herbs such as this are generally not recommended during pregnancy and breastfeeding, for children, or alongside certain medications, especially blood pressure or blood-thinning therapy.
If any of those situations apply to you, or if you take prescription drugs or have a chronic illness, ask your doctor or pharmacist before adding the tea to your routine. That advice is not a sign that the tea is inherently risky; it simply means that such herbs are not appropriate for every person in every situation.
For people who have no such concerns, using a moderate amount at first is a sensible way to see how the tea feels. Even though the blend is caffeine-free, individual responses to herbal ingredients vary. Keep the loose tea in a cool, dry place and stop using it if you notice an unexpected reaction, then discuss that with a specialist.
