Chamomile is one of my most favorite herbs. It is generally gentle and mild and it does help relax a difficult stomach when taken warm.It needs to be taken warm though.However, if someone has a really bad allergy to ragweed, you have to be careful because the gentle chamomile is a memeber of the ragweed family.It doesn't tend to be as prone to trigger the Allergies but it is known to happen and so if you have a headache or other symptoms from it stop using it and choose an alternative.Kamie
