What are the morphological characteristics of this plant?
Avicennia marina has small, elliptical to lanceolate leaves that are opposite or sub-opposite, ranging from 2 to 7 centimeters in length, and possess a distinct grayish-green color with a salty texture. The plant is a woody shrub or tree characterized by a complex branching system and a rugged bark texture. To manage high salinity, it utilizes specialized salt glands on its leaf surfaces to excrete excess salt crystals. It also develops pneumatophores, which are pencil-like aerial roots that grow upward from the anaerobic mud to facilitate gas exchange. These morphological adaptations allow the species to thrive in harsh intertidal environments.
What is the geographical distribution of this plant?
This plant is distributed across the tropical and subtropical coastlines of the Indo-West Pacific, ranging from the East African coast through Southeast Asia to the western Pacific islands. It commonly inhabits intertidal zones and mangrove swamps where saline conditions are prevalent. Its range extends north toward southern Japan and south to the coasts of Australia and New Zealand. These plants thrive in muddy or sandy substrates along tropical shorelines worldwide. Through seed dispersal by ocean currents, the species successfully colonizes distant archipelagos and coastal estuaries.
How is this plant cultivated?
This plant Avicennia marina is cultivated in intertidal zones and coastal salt marshes where it can tolerate high salinity and periodic flooding.
Growers typically select low-lying areas with fine-grained, anaerobic sediments that allow for root stability. Successful establishment requires monitoring the tidal inundation levels to ensure the seedlings receive adequate moisture without complete desiccation. Propagation is often achieved through direct seed sowing or through the use of propagules collected from mature mangrove stands.
Maintaining proper water salinity and managing local sediment accumulation are critical factors for long-term survival in restoration projects.
What parts of this plant are used medicinally?
This plant Avicennia marina provides medicinal benefits through its bark, fruit, leaves, pneumatophores, and roots. The bark is often utilized for its various bioactive compounds that can aid in healing processes. Extracts from the leaves and fruit are frequently employed to treat different ailments due to their antioxidant properties. Even the specialized pneumatophores and the root system contribute to the plant's pharmacological potential in traditional practices. These diverse components work together to provide a wide range of therapeutic applications.
According to a study published by "Indian journal of pharmaceutical sciences", the leaves and bark of Avicennia marina were evaluated for antibacterial activity against Staphylococcus aureus and Proteus sp. The plant gave the best inhibition for these bacterial species and was selected for further investigations. Phytochemical screening of the leaf extracts of A. marina revealed the presence of alkaloids, steroids, triterpenoids, and flavonoids. However, the extracts did not indicate the presence of saponins and cardiac glycosides. Charcoal treated plant extracts of A. marina were able to inhibit both bacterial strains more than those of untreated plant extracts.

What traditional systems uses this plant?
This plant Avicennia marina has been utilized in Persian Folk Medicine for centuries to treat various ailments through its diverse biological properties. Local healers historically applied parts of the mangrove to address skin conditions and promote wound healing. In many coastal regions, the plant's extracts were also used to manage digestive issues and inflammatory responses. Its historical role extends to providing medicinal resources for populations living in salt-marsh environments. These traditional practices highlight the plant's long-standing importance in regional ethnobotanical knowledge.
According to a study published by "Iranian journal of pharmaceutical research : IJPR", Avicennia marina is a species of mangrove tree used for the treatment of small pox lesions in Persian folk medicine. The methanol extract of this plant showed the highest antiviral activity, specifically with its most polar fraction, fraction D, inhibiting HSV with TI and SI values of 57.1 and 133. This same fraction D showed mild activity against HIV with an SI value of 6.25 in fraction 3. Phytochemical investigation revealed that fraction D encompasses flavonoids compounds. This fraction was found to be able to inhibit replication of HSV after entry but did not show significant potency against HIV-1.

What side effects this plant can have?
This plant can cause physiological complications including decreased plasma glucose concentration, increased alanine aminotransferase activity, medullary haemorrhage, monocellular infiltrations, and reduced body weight. These toxic effects often manifest after the consumption of excessive amounts of the plant extract. The disruption of glucose levels and liver enzyme activities indicates significant metabolic and hepatic distress. Furthermore, the presence of medullary haemorrhage and monocellular infiltrations suggests serious damage to internal tissues and inflammatory responses. Ultimately, the cumulative impact of these toxicities frequently leads to a noticeable reduction in overall body weight.
According to a study published by "Journal of applied toxicology : JAT", oral doses of 1 or 4 g kg(-1) for 3 consecutive days or 0.5 g kg(-1) day(-1) for 28 consecutive days were tested on rats. At a dose of 4 g kg(-1), the extract reduced both body and liver weights, whereas a dose of 1 g kg(-1) did not affect them significantly. The extract at both doses significantly increased leucocyte counts, primarily neutrophils, without affecting erythrocyte counts, haemoglobin, or haematocrit. Plasma biochemistry showed a slight decrease in glucose and increases in Na, Ca, Cu, Mg, and cholesterol, along with increased AST and ALT activities. Subchronic treatment resulted in a 15% increase in AST activity and a significant reduction in glutathione concentration of about 20%. Pathological effects included liver cellular degeneration, kidney glomeruli shrinkage, and medullary haemorrhage, though these were milder during the 28-day treatment.
The main side effects this plant can have are shown in the list below.
- decreased plasma glucose concentration
- increased alanine aminotransferase activity
