Marine algae, a diverse group of photosynthetic organisms found in the world's oceans, have gained significant attention for their potential in providing a wealth of bioactive compounds. These compounds have shown promise in various applications, including pharmaceuticals, nutraceuticals and cosmetics. Marine algae are classified into three main types: green algae (Chlorophyta), brown algae (Phaeophyceae) and red algae (Rhodophyta). These algae are rich sources of unique metabolites, including polysaccharides, polyphenols, fatty acids, pigments and terpenoids. These compounds exhibit a wide range of biological activities such as antioxidant, anti-inflammatory, antiviral and anticancer properties. The ecological adaptability of marine algae to harsh marine environments equips them with robust defense mechanisms, making their bioactive compounds particularly potent.

Diabetes mellitus, a chronic metabolic disorder characterized by elevated blood glucose levels, poses a significant global health challenge. According to the World Health Organization (WHO), the number of people with diabetes has risen from 108 million in 1980 to 422 million in 2014, with projections estimating a further increase to 642 million by 2040. Amidst this alarming trend, the search for effective management strategies, particularly those rooted in nature, has gained momentum. Natural products, derived from plants, animals and microorganisms, have garnered attention for their potential therapeutic benefits in diabetes management.

The rise of antibiotic-resistant pathogens has necessitated the search for novel antimicrobial agents. Traditional medicinal plants, with their rich history of use in various cultures, present a promising source of new bioactive compounds. Antimicrobial Resistance (AMR) is a growing global health threat, rendering many standard treatments ineffective and leading to increased mortality, prolonged hospital stays and higher medical costs. Traditional medicinal plants have been utilized for centuries in various cultures to treat infectious diseases. These plants are rich in secondary metabolites, such as alkaloids, flavonoids, tannins and terpenoids, which exhibit diverse antimicrobial activities. This review provides a comprehensive overview of the antimicrobial properties of traditional medicinal plants, discussing their mechanisms of action, efficacy against various pathogens and potential applications in modern medicine.

In a world increasingly inclined towards natural remedies, the spotlight on indigenous herbal teas has intensified. Beyond their soothing flavors and aromatic essence, these teas are celebrated for their potential health benefits, particularly their antioxidant and anticancer properties. As researchers delve deeper into the realm of herbal medicine, evaluating the efficacy of these teas has become paramount. In the quest for effective cancer treatments, nature has long been a source of inspiration. Indigenous herbal teas, steeped in centuries-old traditions and wisdom, have emerged as promising contenders in the fight against cancer. Beyond their comforting brews and aromatic allure, these teas harbor a treasure trove of bioactive compounds with potent anticancer properties.
