1/2 HOUR TO 6 HOURS: It may work as an antacid within 30 minutes and as a laxative it may take 6 hours to 12 hours.

Check with the dosing on the product label, since generally lower doses are used for acid reduction (1-3 TEAspoons), and higher to move the bowels (1-3 TABLEspoons).

Depends: The elimination of this laxative depends on the rate of movement of bowel contents. Under usual circumstances most of it should be out of the GI tract in a couple of days, a week at the most. Unrelated to your question: Practice safe sex. Get HPV vaccine.
