Snake Plant (Lidah Mertua)
(Dracaena trifasciata (Prain) Mabb.)
The Snake Plant originates from tropical Africa and has been introduced to the Americas, Asia, Australia, and the Pacific Islands. This plant is an important economic species used as an ornamental plant and a fiber source in tropical and subtropical regions. More than 20 cultivars are commercialized in nurseries and the landscape trade, mainly due to their variegated, mottled leaves, and wide and attractive leaf shape variation. It is commonly grown as a potted plant kept indoors because the Snake Plant is considered one of the most efficient plants for air purification by absorbing pollutants or removing toxins such as carbon dioxide, benzene, formaldehyde, and trichloroethylene present indoors. The Snake Plant is very long-lived and can survive for over 50 years. Besides being an ornamental plant, it is a source of fiber that can be used to make ropes, mats, and other craft industry raw materials. Traditionally, the Snake Plant has also been used by communities in Africa and Southeast Asia as a medicinal plant. Similarly in Sri Lanka, the rhizome can be used as a traditional medicine to treat cough and cold. Currently, leaf extracts have been used in commercial cosmetic preparations as a skin conditioner.
The Snake Plant can be found growing in tropical, subtropical, and warm climates in a variety of light conditions, ranging from open areas with full sun to shaded areas under the forest canopy. This species is a common weed on roadsides, abandoned gardens, waste areas, disturbed sites, coastal forests, secondary wet forests, mesic forests, and dry forests. It is found at altitudes between 500–1,200 meters above sea level (m.a.s.l.). Its growth prefers areas with an average annual rainfall in the range of 500–1,000 mm, and a soil structure that is sandy, fertile, well-drained, with a soil acidity (pH) between 6–7, but it is tolerant of low-pH (acidic) and high-pH (alkaline) soils, as well as soils with low nutrient content. Furthermore, this species is tolerant of drought and heat.
Root: Fibrous root, white color, has rhizomes that creep below and can also be above the soil surface.
Stem: Covered by the stiff, long, and thick leaves, which causes it to be considered a false stem. The stem is pale white and densely fibrous.
Leaves: Form a basal rosette, the number of leaves in each rosette is about 4–6 leaves in a criss-cross arrangement, inverted linear-lanceolate shape (oblonceolate), thick, erect, stiff, watery, smooth surface, long sword shape, and variegated with grayish-white cross markings, the leaf tip is pointed. The adaxial (upper) surface is generally a greenish-white base color, with irregular dark green horizontal lines.
Flower: Stalked, located in a raceme that grows upright from the base of the stem, solitary or clustered in 2–3 groups, white or greenish-white color. It emits a fragrant aroma, especially at night. The pistil (stigma) and pollen (stamen) are not in the same flower head (implies separate sexes or self-incompatibility).
Fruit: Berry, fleshy, subglobose to oblong-ellipsoid shape, bright orange-red color.
Seed: Monocotyledonous, the outermost part of the seed is a thick coat. However, the seed formation process rarely occurs naturally.
Propagation: Generatively (seeds) and vegetatively (leaf segment cuttings and rhizomes).
Growth: Leaf segments and rhizomes grow easily and can quickly form dense and almost impenetrable thickets. However, seed propagation is rare because the location of the stigma and pollen is not within the same flower head, so pollination usually requires manual assistance.
Treats wounds and snake bites, boils, cough, cold, bronchitis, traumatic injuries, ringworm (kurap), scabies (kudis), fungal infections, diabetes, and hemorrhoids medicine. It has anti-inflammatory activity.
