I'm a little astounded that there hasn't been a more effective physical intervention invented to handle kidney stones and gout. It seems like there should be a way to use high intensity ultrasound waves or something similar to break them up.
Lemons are nice in any case so consuming a bit more of those is not a burden for me. You can work them into food and beverages in all sorts of ways. Probably you should be careful with sugary drinks like lemonade. I wonder what's so special about lemons vs. e.g. oranges, tangerines, grapefruits, etc.
