Uses[ edit ] The invention of the use of Guaiacum for syphilis The genus is famous as the supplier of lignum vitae , which is the heartwood of several species in the genus. It was soon brought back to Europe , where epidemic syphilis had been raging for nearly a century. Gum guiacum quickly acquired a reputation as a cure for syphilis , [11] a practice Benvenuto Cellini records in his memoirs. In A Treatise of the Materia Medica , Scottish physician William Cullen noted: "Several physicians have apprehended mischief from the use of the guaiacum in a spirituous tincture. The resin is used in chronic gout and rheumatism , whilst the wood is an ingredient in the compound concentrated solution of sarsaparilla , which was formerly much used as an alternative in syphilis.

Stuck it in the front, facing the East and it seems to be doing well. It gets water every other day in the summer, then every three days the rest of the year. It took a while to get settled, but it appears to be slowly growing. Just happy to have it, although I know it will take years to reach a height that will be noticeable.

The bottom of the crown is often flat because it is often browsed by livestock and other herbivores. It grows much faster with plentiful water in summer. It is also highly drought tolerant and suitable for xeriscaping.

It can begin flowering on bare branches as the leaves begin to come in when summer rainfall begins. Flowering ranges from sparse to profuse, apparently most floriferous when bloom is preceded by drought. Guaiacum coulteri has been Overexploitation for timber in conjunction with habitat loss and a slow rate of regeneration has left G.

Thus far, my own specimen has done well here in San Jose, CA. Because it is such a rarity, I soak it only once a week While back in Phoenix a few weeks ago, my first stop was Glendale to check upon these specimens, as well as other desert-type trees I have been researching extensively.

Because seed of Guaiacum species are considered recalcitrant remaining viable only for a short period of time after harvesting I sowed what seed id collected for trial immediately after I returned home. At this time, I have at least half a dozen germinated, or in the process.

While I would consider this species highly experimental this far north thus far, it is none the less something every serious plant geek should try. It is simply one of the most stunning treasures of the Sonoran Desert. I lived there 10 years and if flourished the entire time. No, they are not easy to find. If you live in or near Maricopa County, youneed to know about this nursery.

Positive On Jan 9, , conrehabit from Mazatlan, Mexico wrote: We planted 5 Guayacan trees in our property 4 years ago. They were only cms. They are doing very well, with watering twice a week. The picture I uploaded is from an existing tree in our 2 acre site. I collected only 7 seeds from it last winter. Most neighbours "harvest" my tree before I know it.

The 7 seeds germinated in days in small pots in my back patio and they are doing very well. I also got 2 cuttings 2 weeks ago and Isurprinsingly, one is growing small leaves!! I have used cow manure as fertilizer and the most commercial brand as well. The cow manure gave me good results. I have seen at least 1 large 18 feet or taller tree along the Free Highway 15 r I have one growing in my yard in Phoenix. A tough plant. Have to admire that about the Guayacan.

The little leaves come directly off the small branches and even the trunk with the most brilliant bright green coloring. A beautiful shrub to small tree, but relatively hard This plant should be used more. Reward your locally-owned nursery by giving them your business instead.
