Geographical Distributions

Alternanthera sessilis is distributed throughout the tropics and subtropics of America, Africa and Asia; and also throughout Malaysia. [2] A. sessilis is a very common plant of constant or periodically humid, open localities in roadsides, gardens, ditches, swamps, rice fields and tea plantations, and can be found up to 1250 m altitude. [2]

Botanical Description

A. sessilis is a member of the Amaranthaceae family. It is a perennial but sometimes annual herb that can grow up to 1 m tall. It is erect, ascending or creeping, often widely branched, with robust taproot, solid stems, sometimes floating in water and then fistulose in lower part and with smooth hairs. [2]

The leaves are linear-lance-shaped, oblong to ovate or obovate, measuring 1-15 cm x 0.5-3 cm, and hairless or sparsely hairy. The petiole is 1-5 mm long. [2]

Its flowering heads are sessile with 1-veined tepals or only 3-veined at the very base, shiny white or purplish. The filaments are united at base into a very short cup. [2]

The fruit is obreniform, corky and measures about 2 mm long. [2]

Cultivation

No documentation.

Chemical Constituent

A. sessilis has been reported to contain β-carotene [4], ricinoleic acid, myristic, palmitic, stearic, oleic, and linoleic acids [5], α-spirasterol, uronic acid and β-sitosterol [6].

A. sessilis has been reported to contain 33.26% of lutein out of the total carotenoids. [7]

Plant Part Used

Whole plant, leaves, shoots, root [2][6]

Traditional Use

A. sessilis is known to alleviate dementia [8]. It is also used in the treatment of women’s genitourinary infections, vaginal discharge, and post-partum haemorrhage [9].

In Indonesia, A. sessilis entire plant is used as an infusion to treat intestinal cramps, diarrhoea and dysentery, and externally as a cooling agent to treat fever. In Malaysia it is used internally against intestinal inflammation and fever, and externally to treat wounds. A. sessilis is often mixed with other medicinal plants by Taiwanese to treat hepatitis, tight chest, bronchitis, asthma, and lung troubles, to stop bleeding and as a hair tonic. Indian used it as a remedy for dysentery, as a cholagogue, abortifacient, febrifuge, to treat snake bites, and inflamed wounds and boils. While in Thailand and Sri Lanka it is known as a galactagogue. Many places such as Vietnam and Sri Lanka eat the plant as a vegetable. [2]

A. sessilis roots are used for stomachache in Nepal. [6]

Preclinical Data

Pharmacology

Antioxidant activity

The antioxidant activity of A. sessilis was measured by α,α-diphenyl-β-picryl-hydrazyl (DPPH) free radical scavenging activity. The ethanol extract of A. sessilis showed 70% free radical scavenging activity. In the hydroxyl radical scavenging activity assay, A. sessilis showed 50% hydroxyl radical scavenging activity which in the anti-FeCl2-H2O2-stimulated linoleic acid peroxidation system, A. sessilis (2-8 mg) inhibited malondialdehyde (MDA) formation by 11.6 to 30.6%. A. sessilis reduced the peroxide value of heated groundnut and sunflower oil up to 4 weeks of storage. The polyphenol content of the leaves was 25 mg/g. [6]

Toxicity

Oral administration of the water extract of A. sessilis (aerial parts; leaves, stems, flowers) in Swiss mice in daily doses of 16.9mg, 33.8mg and 67.7mg for 14 consecutive days did not result in severe symptoms of toxicity except for diarrhoea in one animal that received the highest dose. In the high dose groups, the water extract of A. sessilis causes histopathological changes in the liver and kidney tissues. There was moderate to severe hepatocyte degeneration in the centrilobular area associated with sinusoidal congestion and focal hepatocellular necrosis, and moderate degeneration of renal tubular cells and necrosis. In a previous study, the alkaloidal extract of A. sessilis injected intraperitoneally into Swiss mice lead to alterations of liver and kidney functions. A. sessilis showed a significant level of cytotoxicity in brine shrimp lethality bioassay. [10]
