The subjects ingested 100 grams of fresh aloe
gel twice a day, in the morning and in the afternoon, for
7 consecutive days. The 24-hr urine was collected one
day prior to taking the gel (Day 0), Day 2 and Day 5 (of
consumption), and Day 8 (one day after finishing the
course). The collected urine was stored cool at 4-8C
without any preservative. Urine specimens with a
creatinine value of less than the formula guide were
discarded(12).
