Botanical Description

Alternanthera sessilis is a highly polymorphic perennial herb, occasionally annual, exhibiting remarkable morphological plasticity depending on its growing conditions.

In drier habitats, the plant develops slender, more solid stems that are erect or decumbent, reaching up to 30 centimetres in height, with much-branched growth. In wetter habitats, the stems are ascending or prostrate, measuring 0.1 to 1 metre in length, often rooting at the nodes, with numerous lateral branches. The floating form produces highly fistular (hollow) stems that can attain several metres in length, exceeding 1 centimetre in thickness, with long clusters of whitish rootlets at the nodes.

Key Identification Features:

Stems range from green to pink or purplish in colour, with a narrow line of whitish hairs running down each side and tufts of white hairs present in the leaf axils. The leaves are extremely variable in shape, ranging from linear-lanceolate to oblong, ovate, or obovate-spathulate, measuring 1 to 9 centimetres in length and 0.2 to 2 centimetres in width. In some specimens, leaves can reach up to 15 centimetres in length and 3 centimetres in width. The petiole is obsolete to approximately 5 millimetres in length.

The inflorescences are sessile, axillary, solitary or arranged in clusters, subglobose in shape, approximately 5 millimetres in diameter, with white, scarious bracts. The flowers have tepals that are ovate-elliptic, measuring 1.5 to 2.5 millimetres, white to pink-tinged in colour. There are five stamens, of which two filaments are anantherous (without anthers). The fruit is obcordate or cordate-orbicular, measuring 2 to 2.5 millimetres, strongly compressed, and exceeds the tepals at maturity. The seed is discoid, approximately 1 millimetre in diameter, brown, shining, and faintly reticulate.

Cultivars: Two distinct colour forms exist: a green cultivar (Alternanthera sessilis Green) and a red cultivar (Alternanthera sessilis Red), distinguished by the colour of their aerial parts.

Distribution: The species is native to tropical and subtropical Asia, Northern and Eastern Australia, and tropical America. It is now naturalised throughout the tropics worldwide. It grows in damp swampy places, marshy areas, ditches, rice paddies, and roadsides, from sea level to 1,000 metres elevation.

Conservation Status: The plant is classified as Least Concern (LC) by the IUCN, with predicted extinction risk being not threatened.

Etymology

The generic name Alternanthera is derived from Latin, combining "alternus" meaning alternate and "anthera" meaning anther, referring to the alternating fertile and sterile stamens in the flowers. The specific epithet sessilis means "without a stalk", describing the sessile (stalkless) flower heads characteristic of the plant.

6. Mechanisms of Action

6.1 Antidiabetic: Alpha-Glucosidase Inhibition

The leaf ethyl acetate fraction acts as a non-competitive inhibitor of alpha-glucosidase, an enzyme that breaks down carbohydrates into glucose in the gut. This inhibition delays glucose absorption and helps manage postprandial hyperglycemia, which is a hallmark of type 2 diabetes.

The leaf ethyl acetate fraction demonstrates an EC50 of 0.55 mg/mL, which is 4.6-fold stronger than the standard drug acarbose. The callus ethyl acetate fraction shows even greater activity with an EC50 of 0.25 mg/mL, representing a 10-fold improvement over acarbose.

The antiglucosidase activity of leaf fractions correlates strongly with total phenolic content (r squared equals 0.97), total flavonoid content (r squared equals 0.98), and total coumarin content (r squared equals 0.97). Chlorogenic acid, in particular, is known to inhibit the enzyme glucose-6-phosphatase, which can reduce hepatic glucose output, contributing to the plant's reported antidiabetic potential.

6.2 Calcium Channel Blockade

The crude ethanolic extract demonstrates a concentration-dependent spasmolytic effect on smooth muscles of the jejunum, trachea, and aorta, comparable to the reference calcium channel blocker verapamil. This mechanism explains the plant's traditional uses in various conditions.

In diarrhoea, the extract relaxes intestinal smooth muscle, providing relief from spasms. In asthma, the extract relaxes bronchial smooth muscle, resulting in bronchodilation. In hypertension, the extract relaxes vascular smooth muscle, resulting in vasodilation. The intravenous administration of the extract dose-dependently decreases mean arterial, systolic, and diastolic blood pressure in normotensive rats.

6.3 Antioxidant Activity

The leaf ethyl acetate fraction demonstrates potent DPPH radical scavenging activity with an EC50 of 10.81 microgram per mL. This activity correlates significantly (p less than 0.05) with total phenolic content (r squared equals 0.99), total flavonoid content (r squared equals 0.97), and total coumarin content (r squared equals 0.96).

The antioxidant activity is central to the plant's hepatoprotective, anti-inflammatory, and anti-aging properties. The high concentration of polyphenols and flavonoids gives the plant a strong capacity to protect cells from oxidative stress and damage.

6.4 Anti-Inflammatory Activity

The methanolic extract significantly inhibits pro-inflammatory cytokines in RAW264.7 cells. Key anti-inflammatory compounds identified include Apigenin-6,8-di-C-beta-D-glucopyranoside, Kaempferol monosulfate, Protocatechuic acid, p-Hydroxybenzoic acid, and Gibberellin.

Beta-sitosterol is a well-known phytosterol with proven anti-inflammatory activity, often compared to that of non-steroidal anti-inflammatory drugs. It works by inhibiting the synthesis of prostaglandins.

6.5 Wound Healing

Bioactive compounds including EGCG, catechin, and ferulic acid enhance cell viability and migration in human fibroblasts and keratinocytes. The 90 percent hydroethanolic stem extract stimulated more than a two-fold increase in the viability of human fibroblasts.

The chloroform extract of the leaves at 200 mg per kg body weight has demonstrated significant wound healing activity in animal models, with a marked reduction in wound area, increased re-epithelialisation, and improved wound breaking strength.

Tannins act as astringents, contracting tissues and reducing bleeding. Saponins have antimicrobial effects, preventing wound infections. The overall effect is a comprehensive approach to tissue repair, combining direct pro-proliferative activity on skin cells with antimicrobial activity.

Formulated Alternanthera sessilis capsules administered to 30 volunteers for 3 months showed no significant increase in liver enzymes or kidney parameters and demonstrated significant increase in haemoglobin and serum ferritin (p equals 0.000). The plant is potentially safe and effective for haemoglobin augmentation in iron deficiency anaemia.

Cardioprotective: Moderate evidence from in vitro and animal studies. The crude ethanolic extract exerts a concentration-dependent spasmolytic and vasodilatory effect on rabbit tissues through a calcium channel blocking mechanism. The intravenous administration of the extract dose-dependently decreased the mean arterial, systolic, and diastolic blood pressure in normotensive rats. Beta-sitosterol and other phytosterols compete with dietary cholesterol for absorption in the gut.

Anticancer: Preliminary evidence from in vitro studies on pancreatic cancer cell lines. The chloroform leaf fraction demonstrated IC50 values of 13.08 plus or minus 10.40 microgram per mL against MIA PaCa-2 cells, 27.19 plus or minus 3.01 microgram per mL against PANC-1 cells, and 34.82 plus or minus 2.20 microgram per mL against Capan-1 cells. The aerial parts showed activity greater than 500 microgram per mL. In vivo studies are lacking.

Antispasmodic: Strong evidence from in vitro studies. The crude ethanolic extract demonstrates concentration-dependent spasmolytic effects on smooth muscles of the jejunum, trachea, and aorta, comparable to the reference calcium channel blocker verapamil.

Antihypertensive: Moderate evidence from in vitro and animal studies. The crude ethanolic extract exerts a concentration-dependent spasmolytic and vasodilatory effect on rabbit tissues. The intravenous administration of the extract dose-dependently decreased the mean arterial, systolic, and diastolic blood pressure in normotensive rats.

10. Safety and Toxicology

10.1 Toxicity Profile

Acute Toxicity: No mortality or toxic symptoms were observed at oral doses up to 2,500 mg per kg body weight in animal studies. The accumulated dose of 10 g per kg body weight showed no signs of toxicity.

Clinical Safety: A Phase I trial confirmed no adverse effects on liver or kidney parameters after 3 months of administration of formulated Alternanthera sessilis capsules to 30 volunteers.

Overall Assessment: The plant is generally recognised as safe for consumption as food and for medicinal use. As with any medicinal plant, concentrated extracts should be used with caution.

10.2 Heavy Metal Considerations

Alternanthera sessilis can bioaccumulate heavy metals from contaminated soil. In the roots, chromium concentration can reach up to 18.86 mg per kg, lead concentration up to 4.94 mg per kg, and cadmium concentration up to 1.98 mg per kg. In the leaves, chromium concentration can reach up to 4.41 mg per kg, lead concentration up to 3.43 mg per kg, and cadmium concentration up to 0.48 mg per kg.

These values should be compared to the WHO and FAO safe limits, which are 2.3 mg per kg for chromium, 0.3 mg per kg for lead, and 0.2 mg per kg for cadmium. The Target Hazard Quotients for cadmium, chromium, and lead were less than 1, indicating negligible health hazard associated with long-term consumption.

Important Recommendation: Sourcing from organic cultivation is recommended as heavy metal concentrations are significantly lower compared to non-organic cultivation.
