Yaa-Knuatmaeo or Folia orthosiphonis showed both favourable and non favourable effects of stone prevention. Uric acid and uric acid containing stone may be prevented by the increased alkalinity of the urine after drinking Orthosiphon tea. The unfavourable effect of orthosiphon being the excretion of oxalate in the urine may result in higher risk of stone formation. However, this study may or may not apply to the stone patients since it has been done only on healthy persons and all parameters were within normal limits. We feel that Orthosiphon tea may be beneficial in prevention of uric acid stone formation. This study was supported by a grant from the Medicinal Herbs Development Fund, Mahidol University.
鸭脚木或猫须草对预防结石既有有利影响也有不利影响。饮用猫须草茶后，尿液碱度增加可预防尿酸及含尿酸的结石。猫须草的不利影响在于其会使尿液中的草酸盐排出，这可能导致结石形成风险升高。然而，这项研究可能适用于结石患者，也可能不适用，因为该研究仅在健康人群中进行，且所有参数均在正常范围内。我们认为猫须草茶可能对预防尿酸结石形成有益。本研究由玛希隆大学草药开发基金提供资助。
