Palo azul (Eysenhardtia polystachya) is also known as palo dulce, palo cuate, cualaldulce, varadulce, and taray by the Tarascans. In Nahuatl, it’s either referred to as cohuatli or tlapalezpatli and in English, it’s Mexican kidneywood. Wood from this small shrub with white flowers, aromatic leaves, and red seedpods was used by the Aztecs primarily to treat kidney problems. It was also a key ingredient in a hiccup remedy and included in another to reduce fever.  

In some areas of Mexico, palo azul bark is used to treat pain associated with rheumatoid arthritis. Studies have shown this traditional use to be valid. It has also been found to have good anti-diabetic activity reducing renal damage caused by diabetes and inhibiting hyperglycemic, hyperlipidemic, and oxidative stress. Its use in the treatment of infection, diarrhea, inflammation, and pain are supported as well. 

Other traditional remedies call for palo azul to treat toothache, cavities, periodontal disease, and gingivitis. Palo azul has antibacterial properties and is effective against both Streptococcus mutans and Porphyromonas gingivalis. It also has moderate cancer fighting properties.

Tea made from Eysenhardtia polystachya is phosphorescent under the right light. The fluorescent compound that causes this is not found in the plant itself, but occurs after a certain flavonoid oxidizes. Some research has been done on using palo azul as a fluorescent biomarker in early-stage cancer diagnosis and pathogen detection procedures and well as drug delivery monitoring since it is non-toxic.
