(1) In experiment 3, 120 volunteers with a mean age of around 50 years were involved, and they were randomly divided into four groups. (2) Group 1 (placebo group) (n = 20): only 10 mg vitamin C daily was taken. Group 2 (n = 20): all subjects took one capsule/day. Group 3 (n = 20): all victims took two capsules daily. Group 4 (n = 20): total volunteers were fed with three capsules in each day. (3) All volunteers took the various doses of mixed herbal capsules for six months in groups 2, 3, and 4 and stopped treatment at end of the sixth month. Then, the participants received follow-up for the next six months. The associated parameters and questions were collected. (4) At first, we compared the AA of at the third, sixth, ninth, and twelfth months with the baseline using Scheffe’s test. Moreover, the results at the ninth and twelfth months were recorded and compared with the outcome of the sixth month by Scheffe’s test. Third, the mean AA in group 2 (1 cap/day), group 3 (2 cap/day), and group 4 (3 cap/day) was compared with the placebo group using William’s test. (5) A value less than 0.05 was considered significantly different. Hence, in the first comparison, it will be marked as, in the second comparison, it will be marked as, and in the third comparison, it will be marked as ^%. (6) Cap/day: capsule(s)/day.
