Green tea and herbal tea are not the same—here’s why

For many Indians, tea has long meant a steaming cup of chai—black tea brewed with milk, sugar, and often flavored with ginger, cardamom, or cloves. It is the drink that accompanies conversations on verandas, railway platforms, office breaks, and family gatherings. 

When someone caught a cold, another brew appeared in the kitchen: tulsi leaves simmered with ginger, black pepper, and honey. Few called it herbal tea then; it was simply a home remedy.

Today, the country’s tea shelves tell a different story. Green tea, chamomile tea, hibiscus tea, peppermint tea, turmeric tea, and dozens of herbal infusions promise everything from better sleep to weight loss and detoxification. As wellness trends have grown, one misconception has quietly taken root: that green tea and herbal tea are essentially the same drink.

They are not.

In fact, from a botanical perspective, one is tea and the other isn’t.

The biggest misconception

The simplest way to understand the difference is to look at where each drink comes from.

Green tea is made exclusively from the leaves of Camellia sinensis, the evergreen shrub that also produces black tea, white tea, oolong tea, and yellow tea. What distinguishes these teas is not the plant but the way its leaves are processed after harvesting.

Herbal tea, by contrast, contains no tea leaves at all. It is technically known as a tisane—an infusion prepared from herbs, flowers, fruits, roots, seeds, or spices. Chamomile flowers, peppermint leaves, hibiscus petals, ginger root, tulsi, lavender, lemongrass, and rose petals are among the many ingredients used to prepare herbal infusions.

Another important difference between the two is that green tea naturally contains caffeine because it comes from the tea plant. Herbal teas are naturally caffeine-free, although exceptions exist when tea leaves are added to herbal blends.

Same ritual, different journey

Both beverages are prepared by steeping ingredients in hot water, but their journey from farm to cup is different.

Green tea grows in tea gardens; young leaves are plucked from the Camellia sinensis plant. After harvesting, the leaves are heated either by steaming, a method popular in Japan, or by pan-firing, commonly used in China. This quick heating prevents oxidation—the natural chemical reaction that darkens tea leaves. The leaves are then rolled and dried before packaging.

Because oxidation is halted almost immediately, green tea retains its characteristic green color, grassy aroma, and high concentration of catechins, a group of plant compounds known for their antioxidant activity.

Herbal tea follows an entirely different path. Flowers are harvested when they bloom, herbs are dried, roots are cleaned and sliced, fruits are dehydrated, and spices are cured before being blended into different combinations. There is no oxidation process because there are no tea leaves involved. The final flavor depends entirely on the ingredients used.

A chamomile infusion tastes nothing like peppermint tea, and ginger tea bears little resemblance to hibiscus. Unlike green tea, herbal tea is not one beverage but an entire family of drinks.

A tale of two health stories

They may have two different methods of preparation; both have health benefits, but for very different reasons.

Green tea is among the most extensively studied beverages in nutritional science. It contains catechins, particularly epigallocatechin gallate (EGCG), a powerful antioxidant that researchers believe may help protect cells from oxidative stress. It also contains L-theanine, an amino acid that promotes calmness, and a moderate amount of caffeine that can improve alertness without the pronounced stimulation associated with coffee.

Studies suggest that regular green tea consumption may support cardiovascular health, improve cholesterol levels, and modestly aid metabolism when combined with a healthy diet and regular physical activity. Emerging research also points to possible benefits for brain health and blood sugar regulation, although scientists caution that green tea is not a substitute for medical treatment.

 Despite widespread marketing claims, green tea is not a miracle weight-loss drink. Its effects on metabolism are generally modest and work best as part of an overall healthy lifestyle.

Herbal teas tell a different story because there is no single “herbal tea.”

Chamomile has been studied for its calming properties and may help improve sleep quality. 

Peppermint is widely used to ease digestive discomfort. 

Ginger has substantial evidence supporting its ability to reduce nausea, including pregnancy-related morning sickness. 

Hibiscus tea has shown promise in helping lower blood pressure in some studies, while tulsi, a cornerstone of Ayurveda, continues to be researched for its potential role in stress management and immunity.

Each herbal infusion carries the characteristics of the plant from which it is made. Their benefits cannot be generalized.

From ancient medicine to modern wellness

Tea’s story began thousands of years ago in China.

According to Chinese legend, Emperor Shennong accidentally discovered tea around 2737 BCE when leaves drifted into boiling water. While historians regard the tale as folklore rather than historical fact, archaeological evidence confirms that tea was first consumed in ancient China, initially for medicinal purposes before evolving into an everyday beverage.

Buddhist monks later helped spread green tea across East Asia, carrying tea seeds and brewing techniques to Japan during the eighth and ninth centuries. Tea became central to Zen Buddhist practice because it helped monks remain alert during long periods of meditation. Over time, Japan transformed tea drinking into an elaborate cultural tradition centered on harmony, respect, purity, and tranquility.

India’s tea journey took a different route. Although indigenous tea plants grew naturally in Assam, commercial cultivation expanded under British colonial rule during the nineteenth century, largely to challenge China’s dominance in the global tea trade. Black tea soon became India’s defining beverage, eventually evolving into the milk tea that millions still enjoy today. Green tea remained a niche product until recent decades, when growing awareness of nutrition, fitness, and preventive health sparked renewed interest.

Herbal infusions, however, have no single birthplace.

Long before coffee became a daily ritual, civilizations turned to herbs for healing. 

Ancient Egyptians brewed chamomile, which they dedicated to the sun god Ra, centuries before modern tea culture emerged. Greek physicians prescribed herbal infusions for digestion and fever. 

In India, Ayurveda—the ancient system of preventive medicine—incorporated tulsi, ginger, and turmeric into medicinal preparations, while Traditional Chinese Medicine developed countless herbal formulations. Across Europe, monasteries cultivated medicinal herbs and brewed botanical infusions long before coffee became widespread.

Unlike green tea, herbal tea is not one tradition but many.

A booming wellness market

The growing popularity of healthier lifestyles has transformed both green tea and herbal tea into billion-dollar industries.

Green tea has become one of the fastest-growing segments of the global tea market. The global green tea market size is valued at USD 24.68 billion in 2026. 

Herbal tea has witnessed equally impressive growth. Market researchers estimate that the global herbal tea market is valued at nearly US$15 billion in 2025 and is projected to expand steadily over the next decade. 

Consumers increasingly seek caffeine-free beverages that support relaxation, digestion, and general well-being. New herbal blends featuring botanicals such as lavender, moringa, turmeric, and ashwagandha continue to enter supermarket shelves each year.

China remains the world’s largest producer, followed by countries such as Japan and India, where regions including Assam, Darjeeling, and the Nilgiris now produce specialty green teas alongside traditional black tea.

Which cup should you choose?

There is no universal winner.

If you are looking for a gentle caffeine boost, improved concentration, and a rich source of antioxidants, green tea is an excellent choice, particularly during the morning or early afternoon.

If your goal is relaxation, better sleep or relief from digestive discomfort, herbal teas may be more appropriate, especially in the evening when caffeine can interfere with sleep.

Ultimately, the healthiest choice depends less on marketing promises and more on understanding what is actually in your cup.

Because in the world of tea, the most important distinction isn’t between green and black, or expensive and affordable.

It’s between tea and something that only looks like it.
