Chamomile is effective in settling indigestion and calming nerves. It also contains antibiotic properties and relieves muscle spasms. It has frequently been offered to birds that are prone to night frights. Chamomile acts as a natural sedative and helps eliminate anxiety and stress targeting those that pluck or chew feathers. It can also be brewed and put into a spray bottle to spray onto affected areas so the bird ingests the tea whilst preening.
