Besides S. jamaicensis being known as a weed : A Part from the Book Chapter : Determination of Plants Diversity and Similarity in Selected three Communities of Stachytarpheta jamaicensis (L.) Vahl

S. jamaicensis

Besides S. jamaicensis being known as a weed, it has the potential as a medicinal and ornamental plant that is often planted by residents around their house as one of the family’s medicinal plants. The leaves of this plant contain chemical compounds such as alkaloids, flavonoids, glycosides, phenols, quinone, phlobotanin, saponins, steroids, tannins, and terpenoids. It had the potential as antimicrobial, antifungal, antioxidant and antidiarrheal, anti-inflammatory and antinociceptive, antihypertensive, anti dyslipidaemia  and hepatoprotective.

This research aimed to determine, the diversity, dominance, evenness and similarity of plant species in three sites growing area of S.

Recent Global Research Developments in Diverse Uses and Plant Diversity of S. jamaicensis

Habitat and Distribution:

  • Native to the Caribbean, including Florida, blue porterweed thrives in coastal areas and disturbed terrain. It’s often found along country roadsides and can be an excellent choice for attracting butterflies and other pollinators, including hummingbirds [1,2].
  • It grows as a low-growing, sprawling wildflower, forming evergreen perennial or shrub-like structures.

Common Names:

  • Blue porterweed goes by various common names, including blue snake weed, bastard vervain, Brazilian tea, and Jamaica vervain [3].

Medicinal Uses:

  • The fresh leaves of S. jamaicensis are consumed in bush tea. They are believed to have cooling and blood-cleansing properties.
  • However, caution is necessary: Tea brewed from this plant has been associated with mild non-dose-dependent systemic toxicity in various tissues, including the liver, kidneys, and lungs.

Ecological Importance:

  • Blue porterweed plays a role in attracting pollinators, contributing to biodiversity.
  • It blooms throughout the year and can be used in container gardening, as a groundcover, or in mass plantings [1].

Similar Species:

  • Be aware that Stachytarpheta cayennensis, an invasive species in Florida, resembles S. jamaicensis and may be mistaken for it.
