DMMB [1,3-dimethoxy-5-methylbenzene] is a key component of the fragrance element commonly referred to as 'Tea'. This component...has a relaxing effect (sedative properties) and is originated from Rosa gigantea Collett native to southwestern China throught Myanmar (Shoji et al., 2000; Yomogida, 2004).
