A Review on Potential Health Benefits of Fenugreek Seeds, Flaxseeds and Curry Leaves

Abstract

Several illnesses affecting humans are progressing much more quickly due to modern lifestyle choices, eating habits, stress, environmental variables, and extensive use of synthetic chemicals in food processing and agriculture. Worldwide, researchers have been searching for natural therapeutics that can be utilized to either treat or postpone the onset of various lifestyle-related illnesses. Due to the presence of various bioactive chemicals, several different kinds of medicinal plants have demonstrated the potential to be commonly used in therapies. Some of them are Fenugreek seeds, Flaxseeds and Curry leaves. Each of these natural ingredients is rich in bioactive compounds, including dietary fibers, essential fatty acids, alkaloids, and polyphenols, which contribute to their diverse pharmacological effects. Fenugreek seeds are known for their anti-diabetic, hypocholesterolemic, and gastroprotective activities. Flaxseeds, a potent source of alpha-linolenic acid (ALA) and lignans, are linked to cardiovascular protection, hormonal balance, and anti-inflammatory effects. Curry leaves, widely recognized for their antioxidant, hepatoprotective, and antidiabetic properties, are also a vital source of essential micronutrients. This review consolidates recent scientific findings and traditional knowledge to highlight the preventive and therapeutic potential of these ingredients.

Introduction

In recent years, there has been a growing global interest in the use of natural, plant-based ingredients for the prevention and management of various health conditions. Among these, Fenugreek seeds, Flaxseeds and Curry leaves have garnered significant attention due to their rich phytochemical profiles and wide-ranging therapeutic properties. Traditionally used in Ayurvedic and other indigenous medical systems, these ingredients are now being recognized by modern science for their numerous health-promoting effects. Fenugreek seeds are a rich source of dietary fiber, saponins, alkaloids, flavonoids, and amino acids such as 4-hydroxyisoleucine. These compounds are associated with antidiabetic, hypolipidemic, and anti-inflammatory activities, making fenugreek an effective functional food for managing metabolic disorders. Similarly, flaxseeds are packed with alpha-linolenic acid (ALA), lignans, and mucilage, offering potent antioxidant, cardioprotective, and hormone-balancing benefits. Their consumption has been linked to improved cardiovascular health, reduced inflammation, and potential anticancer properties. Curry leaves, a staple in Indian cuisine, are not only flavor enhancers but also a source of numerous bioactive compounds such as carbazole alkaloids, phenolics, and essential oils. These compounds have been shown to possess antioxidant, hepatoprotective, antidiabetic, and neuroprotective effects. The traditional use of curry leaves in managing diabetes, gastrointestinal issues, and hair and skin conditions is now being substantiated by scientific studies.

This review aims to provide a comprehensive overview of the nutritional composition, pharmacological activities, and potential health benefits of fenugreek seeds, flaxseeds, and curry leaves. By integrating traditional knowledge with current research, this paper seeks to highlight their role as functional foods.
