Buchu is native to the Cape region of South Africa where it was used as a general stimulant and diuretic by the Khoisan people.
Two main species of buchu are commonly used for medicinal purposes: Agathosma betulina (round-leaf buchu) and Agathosma crenulata (oval-leaf buchu).
Note, however, that results on the efficacy of buchu are inconsistent and that strong recommendations cannot be made.
Traditional uses:
- General health tonic
- Mild urinary antiseptic (treats mild cystitis and prostatitis)
- Appetite stimulant (in small doses)
- Aids digestion
- Antispasmodic
- Diuretic (treats water retention)
- Stimulant (treats hangovers)
- Also used to treat colds and flu, coughs, rheumatism and gout
Buchu is also a source of potassium, calcium, magnesium, manganese, nitrogen, iron, copper, zinc and boron.
Interesting facts:
Buchu is indigenous to South Africa and is believed to have been the country's first export product. Currently, about 90% of our buchu is exported.
Medicinal use of buchu dates back to the Khoisan people. These plants have also traditionally been used as a fragrance in perfume.
Buchu has a distinctive blackcurrant flavour.
Buchu can be taken orally in the form of an infusion or as a tincture in brandy ("boegoebrandewyn"). The leaves can also be chewed fresh or dried.
Caution:
As buchu has a mild laxative effect, the herb should not be taken in excess.
The use of A. betulina is generally preferred, as A. crenulata contains high levels of pulegone, a potentially toxic substance.
