Urine therapy in Ayurveda: Ancient insights to modern discoveries for cancer regression

Abstract

Investigation of spontaneous regressions (SR) of cancer may explain host mechanisms of control by anticancer substance (A.C.S.). Documented human SR, of bladder cancer after uretero-sigmoidostomy and of uterine leiomyosarcoma after irreparable vesico-vaginal fistula, suggested the presence of A.C.S. in human urine. Animal experiments with urine in rat alveolar carcinoma and in mouse melanoma point to A.C.S. Urine therapy, as cited in Bhrigu-Samhita and used in some cases, needs to be followed up by systematic Reverse Pharmacology and analytical identification of A.C.S.
