The instrument used to assess the level of cramping pains (dysmenorrhea) was questionnaires using Descriptive Verbal Scale (VDS), which consisted of 6 levels of pain. Results: The results showed that before the treatment, the level of cramping pain of 17 respondents was moderate (68%, N = 25) and that of 7 respondents was severe (28%, N = 25). After the treatment, 18 respondents (72%, N = 25) did not experience cramping pain at all and 6 respondents (24%, N = 25) experienced mild pain.

Scientific research has proven the beneficial effects of Noni to overcome the pain. In 1990, researchers found a significant relationship between the dose of extract of Noni juice with analgesic activity on guinea pigs. Generally, the more widely used, the analgesic effect will be stronger. (Magdalena, 2011). Studies and research on Noni continues to be done by various research institutions and universities. Dr.Ralph Heinicke (1972), a famous biochemist from the United States found out that the Noni fruit contains xeronine and its precursor (proxeronine) in large numbers. Proxeronine is a type of colloid acid that does not contain sugar, amino acids or nucleic acids
