Pretty big news with quite a few articles making the rounds:

Could this be the end of painful kidney stones? Compound found in citrus fruit ‘dissolves crystal deposits’
Kidney stones are hard mineral deposits that build up inside the kidneys
Study found hydroxycitrate (HCA) compound can dissolve the crystals
HCA is found naturally in the Garcinia Cambogia plant grown in Asia
Discovery marks the first advance in kidney stones treatment in 30 years

Painful kidney stones could be dissolved by a natural citrus fruit extract called hydroxycitrate (HCA), a study has found. HCA is in the Garcinia Cambogia fruit (pictured), used widely in Asia

Lead author Dr Jeffrey Rimer, of the University of Houston, said: ‘HCA shows promise as a potential therapy to prevent kidney stones - HCA may be preferred as a therapy over potassium citrate.’

_Rimer said the research may lead to an effective drug but more human trials are needed and long-term safety needs to be factored in. _
“…HCA has the potential to reduce the incidence rate of people with chronic kidney stone disease.”
