      Jacaranda gualandai. *N.O. Bignoniaceae. Tincture of dried leaves.


Blenorrhagia. Chancroids. Diarrhoea. Eye, inflammation of. Gonorrhoea. Leucorrhoea. Syphilis. Throat, sore.


*J. gualan. was first brought to the notice if homoeopathy by Dr. Julio F. Convers of Bogato, Columbia, South America (*H.R., iv. 36, v. 149, ix. 343). Mr. Jose M. Reyes made a proving for Dr. Convers (see also *Medorrhinum Adv., xxii 244), taking considerable doses if the O tincture in the first instance, and later of the 3x. The chief symptom of the heavy dosing was a painless, blackish, and mulberry-coloured diarrhoea which persisted a long time and was finally cured with *Mercurius 12 after *Arsenicum had failed. This cure by *Mercurius is important in regard to the popular use of the plant in syphilis. Convers says the natives use it much in syphilitic affections and atonic ulcers, and he adds that “the prostitutes are very fond of it.” The proving developed an action on the glans penis. When the 3x was taken there was severe ophthalmia, chiefly affecting the left eye, ” a syphilitic like ophthalmia.” The pharynx and larynx were also affected, which organs are favorite *loci of syphilis. Convers has confirmed these observations. He prefers it to any other remedy in ophthalmia with agglutination of the lids, blenorrhagia and chancroids, sore throat with redness and heat and vesicles on pharynx without swelling of tonsils, in catarrhal leucorrhoea. In the Schema I have put in brackets Convers’ additions to Reyes proving. Convers symptoms are worse at night and worse by laughing or talking. Convers prefers O tincture, locally and internally for sore throat, and the 3rd for ophthalmias and catarrhs. It is an innocent remedy. The symptoms develop first in the head, next in the intestines, lastly in eye and throat.
