Larrea tridentata Chaparral The leaves and twigs are used by Native Americans to make a herbal tea used for a variety of conditions, including arthritis, cancer and a number of others. Subsequent studies have been extremely variable, at best. Chaparral has also been shown to have high liver toxicity, and has led to kidney failure, and is not recommended for any use by the U.S. Food and Drug Administration (FDA) or American Cancer Society.[106][107]

It can also ease any inflammation that may be irritating your throat. Its main constituent, glycyrrhizin, is responsible for most of its effects. 30-50 times sweeter than sucrose (table sugar), it inhibits an enzyme 11beta-hydroxysteroid dehydrogenase (how would like you to write that on a name tag?) This enzyme regulates access of glucocorticoid (a steroid hormone) to steroid receptors, ultimately slowing the conversion of cortisol to cortisone. This increases the effect of cortisol and reducing inflammation. If you are on steroids, or have any problems with your kidneys, it is best to steer clear of licorice root.
Eating a clove or two of fresh garlic a day may indeed keep the doctor away, in part because it has immune-boosting, antibacterial, antiviral, and anti-fungal effects. Many of garlic's therapeutic effects are derived from its sulfur-containing compounds, such as allicin, which are also what give it its characteristic smell. In general, garlic's benefits fall into four main categories:
