Some claim that it is useful in managing diabetes. It is also suggested that this plant is useful in treating other medical conditions, amongst which are fibromyalgia (FMS) and lupus (SLE). This herbal tea is used by many during the cold and flu season, and is a remedy for smoker's cough. Another medicinal use of Pau d'Arco is as an expectorant: to promote "coughing up" by the lungs in order to free mucus and contaminants that had been lodged there.
Pau d'Arco tea or tincture concoctions have reportedly had beneficial effects for cancer patients, anywhere from alleviation of chemotherapy symptoms to complete remission of tumors.
Candida Albicans, a fungus which causes yeast infections, has also been treated by the Pau d'Arco herb. Aside from patients dealing with candida problems, those with other issues involving fungi or yeasts -- such as Aspergillus -- may also be helped due to the antifungal nature of lapachol. Moreover, it is claimed that certain bacteria are affected by this compound, so help may also be available for people with issues of that nature, including: C. diff, Staphylococcus aureus, Streptococcus, Helicobacter pylori (common cause of stomach ulcers), Brucella, tuberculosis, pneumonia, and dysentery.
