Lemongrass, with its distinctive aroma and tangy flavor, has found a crucial place in various cuisines, particularly in Southeast Asian dishes. However, many enthusiasts and culinary explorers often wonder, “Is lemongrass a herb or vegetable?” This question not only touches upon the botanical classification but also delves into culinary applications, health benefits, and much more. In this extensive article, we will explore the intricacies of lemongrass, aiming to clarify its status in both the botanical world and the culinary sphere.
Understanding Lemongrass: A Brief Overview
Before diving into whether lemongrass is classified as a herb or vegetable, it’s essential to understand what lemongrass is. Scientifically known as Cymbopogon citratus, lemongrass is a tropical plant that belongs to the Poaceae family, which is better known as the grass family. This plant thrives in warm climates and is native to regions of Asia, particularly India and Sri Lanka, where it has been used for centuries.
Lemongrass typically grows in dense clumps and can be around three to four feet tall. The leaves are long, narrow, and green, while the stalks, which are commonly used in cooking, are thicker and have a more robust flavor profile. The unique citrusy scent is where it gets the name “lemongrass,” as it resembles the fragrance of lemons, even though it isn’t a citrus fruit.
Herbs vs. Vegetables: Defining the Terms
To answer the question about lemongrass being a herb or a vegetable, it’s crucial first to clarify what we mean by these terms.
What is a Herb?
A herb is typically defined as a plant that is valued for its medicinal properties, flavor, or aromatic qualities. Herbs can be either annuals, biennials, or perennials and are often characterized by their leafy green parts used for seasoning or remedies. They can be used fresh or dried and are generally part of the plant that grows above the ground.
What is a Vegetable?
Vegetables, on the other hand, include a broader range of edible plant parts, such as roots, stems, leaves, flowers, and fruits. The classification of vegetables is primarily based on the culinary use of the plant rather than botanical definitions. Unlike herbs, which are often used for their potent flavors, vegetables can be more substantial components of a dish, and they tend to offer a variety of flavors and textures.
The Case for Lemongrass: Herb or Vegetable?
Based on the definitions of herbs and vegetables, lemongrass fits the characteristics of both, but it is more accurately classified as a herb. Let’s explore the reasoning behind this classification in detail.
The Botanical Classification
From a botanical point of view, lemongrass, being a member of the grass family, does not possess the typical qualities of traditional vegetables like carrots or potatoes. Instead, it falls under the category of aromatic herbs because it is primarily valued for its flavor. The stalks and leaves of lemongrass are the parts used in culinary applications, which enhances dishes more like an herb than a traditional vegetable.
Culinary Applications of Lemongrass
Lemongrass is primarily used as a flavoring agent in cooking. Its citrus notes make it a perfect addition to a wide range of dishes, especially in Asian cuisine. Some common culinary applications include:
- Soups: Lemongrass is often used in nourishing broths, such as Thai Tom Yum soup, where it imparts a refreshing taste.
- Curries: It adds zesty flavor to curries and stir-fries, making dishes more vibrant and aromatic.
Besides these culinary uses, lemongrass is also used in beverages, teas, and desserts. The versatility of lemongrass highlights its primary role as an herb rather than a vegetable.
Health Benefits of Lemongrass
One of the reasons lemongrass is highly regarded is its myriad of health benefits. Being an aromatic herb, it is rich in essential oils and antioxidants, contributing to its therapeutic properties. Here are some notable health benefits of lemongrass:
Digestive Aid

What is lemongrass classified as, herb or vegetable?
Lemongrass is technically classified as an herb. It belongs to the grass family Poaceae and is known for its aromatic properties. In culinary terms, herbs are typically plant parts used for flavoring or garnishing, and lemongrass is often used for its zest and fragrance in various dishes, particularly in Asian cuisines.
Despite being used to flavor foods like a vegetable, lemongrass does not grow as a traditional vegetable would. Instead, it has a stalk-like structure and is much more potent in flavor than many typical vegetables, adding a distinctive citrus note to soups, curries, and teas.
How is lemongrass used in cooking?
In cooking, lemongrass is versatile and is commonly used to impart a fresh, lemony flavor to a variety of dishes. It can be found in everything from broths and soups to marinades and dressings. The stalks can be bruised and then added whole to dishes for infusing flavor, or they can be finely chopped for more immediate flavor release.
It is worth noting that lemongrass is often used in Thai, Vietnamese, and Indian cuisines. Its bright flavor complements a wide range of proteins and vegetables, making it a popular choice for both meat-based and vegetarian meals. Additionally, lemongrass is also used in herbal teas and cocktails, showcasing its adaptability in the culinary world.
Can lemongrass be grown at home?
Yes, lemongrass can be easily grown at home, whether in a garden or in pots. It thrives in warm, humid conditions and requires plenty of sunlight and well-draining soil to grow successfully. You can propagate lemongrass from stalks bought at the grocery store by placing them in water until they develop roots and then transferring them to soil.
When growing lemongrass, it’s important to keep the plant well-watered but not overly soggy. Regular pruning will promote healthy growth and a bushier plant, allowing for a steady supply of fresh lemongrass for culinary use right from your home garden.
Are there any health benefits associated with lemongrass?
Lemongrass is not only valued for its flavor but also for its potential health benefits. This herb is known for its antioxidant and antimicrobial properties, which can help support overall health by combating oxidative stress in the body. Many people consume lemongrass tea as a natural remedy for digestive issues, anxiety, and even insomnia.
Additionally, lemongrass is believed to have anti-inflammatory effects, making it a good addition to diets aimed at reducing inflammation in the body. Its essential oils are often used in aromatherapy to promote relaxation and mental clarity, showcasing how this herb has beneficial applications beyond the kitchen.
Can lemongrass be eaten raw?
Yes, lemongrass can be consumed raw, but its tough and fibrous texture makes it less palatable in its raw form. It is typically used in small amounts and added to salads, salsas, or used as a garnish, allowing the subtle flavor to enhance the dish without overwhelming it. It’s often finely minced or ground to incorporate it more easily.
Eating raw lemongrass can provide some of the same health benefits associated with cooked varieties, including its refreshing taste and potential antioxidant properties. However, most culinary applications favor cooked lemongrass, as the heat helps soften the fibrous stalks and releases the essential oils that make it so flavorful.
How do you prepare lemongrass for cooking?
Preparing lemongrass for cooking involves a few simple steps to ensure you get the most flavor from the stalks. First, you should trim off the thick, woody ends of the stalk and remove the outer layers to expose the tender core. Afterward, you can either slice it thinly for dishes where a more pronounced flavor is desired or bruise the stalks using the back of a knife to release their essential oils.
For broths and soups, whole stalks can be added and later removed before serving, infusing the liquid with a mild lemony taste. When using it for marinades or sauces, finely chopping the tender part or grinding it into a paste can help integrate the flavor thoroughly into your dish, allowing you to enjoy the aromatic qualities of this herb to the fullest.
