Abstract

Coastal communities have empirically utilized and proven the medicinal properties of mangrove plants. The objective of the study was to determine the species diversity of mangrove plants and their use as herbal medicine on the coast of Lampung Timur, Sumatra, Indonesia. Mangrove plant diversity was obtained through vegetation analysis and diversity index calculation. The use of mangroves as medicine was obtained through interviews and descriptive comparative analysis. The study revealed that the mangrove forest located on Lampung Timur Coastal comprises 22 species from 12 families. Out of these 22 species, 12 are true mangroves, and the remaining 10 are mangrove associates. Among the 12 true mangroves, the majority (10 species) are major mangroves, while the other two are minor. The diversity index of the Lampung Timur mangrove forest is categorized as moderate (H'= 1.9580). The use of mangrove plants as herbal medicine persists in the Lampung Timur Coastal community. Among the users of mangrove herbal medicine, the majority (55.71%) are from the older generation. Additionally, 64% of users are male, 57.37% are categorized as low-income, and 60.12% identify as Javanese based on ethnicity. The community uses various plant species for medicinal purposes. Avicennia marina is used as an antiseptic, anti-histamine, and source of vitamins. Acanthus ilicifolius is used as an anti-rheumatism and muscle ache medicine/analgesic. Rhizophora apiculata is used as an antipyretic, R. mucronata is used to increase stamina/vitality, and Soneratia caseolaris is used as an anti-cholesterol and anti-oxidant.

Abstract

Avicennia marina has at least 36 types of flavonoid compounds that are potential anti-fertility agents. The study's objectives were to obtain safe doses and assess the potential risks of using A. marina extract. Toxicity testing was conducted on Wistar rats with doses of 0, 250, 500, 1000, 2000, and 4000 mg/kg BW for leaf and fruit extracts. Observations were made to measure the level of mortality and damage to important organs (liver, kidneys, and testes) both macroscopically and microscopically. Macroscopic observation included identifying changes in shape, color, and size. Microscopic observation was done to observe organ damage through histopathological tests. Results of the study show that the administration of A. marina extract, both leaf and fruit, resulted in a 100 % survival rate at all doses given and the LD50 >8 g/kg BW. Both leaf and fruit extracts of A. marina also did not cause a decrease in the size of the kidneys and testes, but at high doses, they potentially reduced liver size. These findings indicate that using A. marina extract at recommended doses is safe. Both leaf and fruit extracts of A. marina, at a dose of 250 mg/kg BW, did not cause negative effects on the major organs (liver, kidneys, and testes) of mice. This finding suggests that using A. marina extract at 250 mg/kg BW is safe for long-term use. Administration of A. marina extract at doses up to 500 mg/kg BW did not cause liver damage in mice, but it potentially caused mild kidney damage. This finding indicates that leaf and fruit extracts of A. marina still have the potential to be used as drug candidates but with dosage regulation below 500 mg/kg BW. Administration of leaf and fruit extracts at doses of 500, 1000, and 2000 mg/kg BW has been shown to reduce the fertility of mouse sperm cells by up to 30%. This finding indicates that A. marina has the potential to be a promising, safe herbal anti-fertility agent.
