Buchu (Agathosma betulina)

Buchu Overview:

Buchu is best known for its effects on the urinary tract. It's a diuretic, increasing the flow of urine, and speeding filtration in the blood. it works differently to most diuretics, however, by increasing blood flow to the kidneys, allowing them to work harder on their own accord. other diuretics tend to work by decreasing the reabsorption rates in the nephrons.

Buchu is a diuretic, but it is also a urinary antiseptic. It's effective for treating urinary tract infections in men and women. t has a much gentler action than other urinary tract infections, which makes it useful for children, the elderly, and those with weak or chronically damaged urinary tracts.
