This study consisted of three sub-studies including 1) development and evaluation of body massage oil from Snake fruit on skin moisture, elasticity, oiliness, and melanin in healthy participants 2) development and evaluation of facial mask from Snake fruit on skin moisture, elasticity, oiliness, and melanin in healthy participants and 3) development and evaluation of ready-to-drink jelly from Snake fruit on controlling blood glucose and endurance time in healthy participants.

Study 1: senventy-one male and female participants, aged 23.99 ± 5.68 years were randomly assigned into 3 groups including 1) control group (n = 23): participants received Thai massage without any oil for 1 hour/day, 1 day/week for 12 weeks 2) treatment-1 group (n = 23): participants received Thai massage with pure coconut oil which is a popular oil used in spa for 1 hour/day, 1 day/week for 12 weeks and 3) treatment-2 group (n = 25): participants received Thai massage with oil mixed with Snake fruit extract for 1 hour/day, 1 day/week for 12 weeks.

Study 2: fifty-nine male and female participants, aged 23.39 ± 4.84 years were randomly assigned into 2 groups including 1) control group (n = 29): participants did not receive any facial mask for 12 weeks and 2) treatment group (n = 30): participants received home-based program facial mask with Snake fruit extract for 30 min/day, 2 days/week for 12 weeks.

Study 3: this study was divided into 2 sub-stidies. Study 3.1: twenty-five male and female participants, aged 22.60 ± 3.33 years were randomly consumed with either control jelly or jelly with Snake fruit juice at 3.5 g/kg body weight. All participants were analyzed for blood glucose level before consumption and after consumption at 30, 60, 90, and 120 min. Study 3.2: twenty-three male and female participants, aged 21.57 ± 1.88 years were randomly consumed with either control jelly or jelly with Snake fruit juice at 3.5 g/kg body weight. After each consumption, all participants performed leg cycling at intensity 60% of maximal oxygen consumption as long as tolerance (time to exhaustion test).
