Yes its great for all systems functions. If you increase too much too quickly you can get a bit of diarea.
You can take as much as your system can handle, nausea, diarea, other detox affects being the outcome of high doseing. 8 oz straight is not unusual for the initiated and internally clean. Tho again, I prefer diluted. 6 oz in a half gallon of water with a guart or more of any juice. Evan 2 oz into a gallon of water makes a nice tonic. Tho evan at low concentrations the congested cant quite stomach these grass juice concoctions, but the healthy love them.
