Celestial Seasonings has been making Red Zinger tea with a proprietary blend of herbs and spices since 1972. The primary ingredient that may have a therapeutic effect if you drink the tea in large-enough dosages is Chinese hibiscus. The remaining trace ingredients include cherry bark, peppermint, West Indian lemongrass, orange peel, lemon myrtle and licorice. Tea can be an effective medicinal form, as opposed to pills and tinctures, because of the quick the rate of digestion and corresponding relief of symptoms. Additionally, some practitioners believe that when patients prepare their own remedies, such as teas, they become more involved in their therapies, which can lead to better results, according to "Acupuncture Today." Remember, you should always talk to a doctor before using any herbal remedy.
