Uses

The roots of P. scutellarioides are used internally in the Moluccas to treat diarrhoea and colic, and the leaves as anthelmintic and to treat urinary complaints, whereas sap is squeezed into the eye in the case of eye injury, and rubbed on swellings. Elsewhere in Indonesia the sap or a decoction is used as an abortivum and emmenagogue, and to treat haemorrhoids, inflamed eyes and boils. In Malaysia, a decoction of the leaves is used to stimulate digestion, as a sedative, to treat dyspepsia and congestion of the liver, and externally against swellings, smallpox and ophthalmia. Fresh leaves are applied in the Philippines externally or in cataplasm to bruises and contusions, and to treat headache. In Papua New Guinea, young leaves are baked and squeezed whilst hot onto fresh cuts and sores. P. scutellarioides is commonly cultivated for its ornamental purplish foliage.

Observations

  • An erect or ascending, branched perennial herb up to 150 cm tall, non-tuberous.
  • Leaves generally ovate, 1-15 cm × 1-10 cm, membranaceous.
  • Flowers in lax verticillasters or in irregularly branched cymes disposed in simple or branched thyrses, calyx 2-lipped, corolla about 8-13(-18) mm long, blue or violet with whitish tube.
  • Nutlets broadly ovoid or globose, 1-1.2 mm long, shining, brown.

P. scutellarioides occurs in all kinds of habitats, from rain forest to cropped fields and thickets, and from the lowland to 2900 m altitude.
