'The Lapacho tree has been studied for many years by cultures around the globe. It is an evergreen tree from South America that produces a type of bark that has been claimed to cure or prevent cancer, along with other illnesses. The scientific name is Tabebuia avellanedae, and the tea that is made from this bark is often referred to as "Pau d'arco," though many alternative names have been used.
The University of Maryland found that this specific tea, or bark extract, has anticancer properties, as well as anti-inflammatory, antiparasitic, antifungal and antimicrobial properties. There has not been any well-known testing on humans, but studies have already proven that this particular bark provides a stimulation of immune system cells known as macrophages. Additionally, this bark has been reported to kill lung cancer cells and liver cancer cells that were grown and analyzed in a test-tube study.'
