Buchu is a natural diuretic.
It has an effective flushing action on the kidneys, and is a great treatment for urinary tract and prostate infections, cystitis, gonorrhea, impotence and low sperm count.
Fluidex and Odrinil are two common prescription medications that relieve premenstrual bloating, both contain Buchu.
The native peoples of southern Africa, most prominently the Khoi San of the western Cape region, pioneered the medicinal use of buchu, employing it to treat urinary problems.
Buchu may also be used as a douche for leucorrhea (white vaginal discharge) and occasionally for yeast infections. The herb is a uterine stimulant and contains pulegone, which is also present in large quantities in pennyroyal. Pulegone is an abortifacient and a powerful emmanagogue (stimulates menstrual flow). Buchu should not, therefore, be taken during pregnancy
