The yellowish, tough wood of the lignum vitae tree caught the attention of the first Spanish people traveling to America. From the 16th century onwards, the lignum vitae tree was brought to Europe and is known as the “wood of life” (lignum vitae). Up until the late 19th century, it was considered able to heal tuberculosis and even syphilis. We currently know its actual properties.

Healing Properties and Indications
The wood of the lignum vitae tree exudes a resin whose most crucial active component is guaiacol. This resin also contains saponins, gum, and an essential oil, which give the plant the following properties:
- Balsamic and expectorant are recommended in the case of any respiratory afflictions.
- Diuretic, sudorific, and depurative: It eliminates uric acid and other waste substances from the blood in rheumatism, arthritis, and gout. Because of its depurative properties, it is also recommended for people suffering from hypertension and arteriosclerosis. In Central America, the lignum vitae is still used against syphilis, though its effectiveness has not been proven.
