Caffeine is a bitter ingredient found in numerous beverages, foods, supplements and medications. As a stimulant, people often reach for caffeine in the form of coffee or other beverages for boosted energy. Many herbs and teas provide natural alternatives to caffeine. In addition to energy enhancement, they may benefit overall wellness, according to natural health expert, Andrew Weil, M.D. Since natural stimulants may cause side effects, a doctor's guidance is recommended prior to their use.
Siberian Ginseng
Siberian ginseng is a plant used throughout history in countries such as China and Russia for improved immune system strength and other benefits. According to the University of Maryland Medical Center (UMMC), Siberian ginseng is currently credited for benefits toward improving energy, vitality and longevity. Though research is limited, Siberian ginseng may also enhance athletic performance and cognitive function, similarly to caffeine. Siberian ginseng is available in dried root, tea, capsule and extract form. It is also present in many energy-enhancing beverages in the United States. According to the UMMC, recommended dosage of Siberian ginseng, in root form, varies from between 500 and 3,000 milligrams (mg) daily. In high doses or when used for treatment for health problems, a doctor's guidance is suggested.
Green Tea
To produce green tea, preparers steam, roll and dry leaves of the camellia sinensis--the plant that supplies leaves for most other teas as well. According to Weil, the process used to create green tea is what makes it superior in nutrient content and benefits when compared to other teas, as it preserves content of disease-fighting nutrients called polyphenols and catechins. Green tea, whether caffeinated or not, may provide uplifting sensations, similar to caffeine. Some people describe green tea as a calmer form of energy, in contrast to the "rush" that may derive from caffeinated coffee and energy drinks. Green tea may also modestly increase metabolism and promote weight loss--effects frequently associated with caffeine.
American Ginseng
American ginseng is similar to Siberian ginseng in that it promotes energy; however, American ginseng is derived from an entirely different plant and varies in chemical make-up and active ingredients. According to the UMMC, American gingeng is referred to as an "adaptogen," meaning it helps the body combat internal stress. Though scientific evidence is lacking regarding the healing benefits of American ginseng, it remains popular in the United States, often as a caffeine alternative. In addition to improved energy, American ginseng is believed to support heart health, cognitive function in people with attention deficit hyperactivity disorder (ADHD) and immune system strength. Dried American ginseng is available in water or alcohol-based mixtures, liquid extracts, and in powder, tablet and capsule forms. Ginseng is also frequently combined with other herbs in dietary supplements. Since all dietary supplements may pose side effects, doctor's guidance is suggested before taking ginseng in supplement-form.
