The Magenta plant or Dicliptera tinctoria
The Magenta plant or Dicliptera tinctoria is a herbaceous perennial plant native to southeastern Asia from Assam south to Sri Lanka and east to mainland Southeast Asia, Java, southern China, and Taiwan.
It grows up to 1 m tall. The flowers are two-lobed, the long axis up to 5 cm long; they are magenta to reddish-violet.
An extract of its leaves is used as a food colouring, and imparts a magenta tone to some Vietnamese foods, particularly in glutinous rice dishes such as xôi lá cẩm, a sweet dessert.
The plant is used in traditional Chinese medicine. The leaves have been used in water extract decoctions for the treatment of ailments including cough, dysentery, diarrhoea and bronchitis.
(The plant was earlier known as Peristrophe bivalvis)
