I'm sorta confused on the Celery seed remedy on this site. It mentioned to use Celery seed to help cure kidney disease, but it says Celery seed is toxic and should not be taken if you have kidney disease. Can somebody shed some light on this? I wanted to try this but afraid I may have kidney disease. Should I try the Watermelon seed instead? What are the best route on cleansing the kidney? And how long does it take?
