What Is Pennywort Juice? A Guide to Vietnam’s Rau Má Drink

If you’re exploring Vietnamese street drinks, pennywort juice is one of the most distinctive drinks you can try. Known locally as rau má, it is made by blending fresh pennywort leaves with water and serving the green juice over ice. Its flavor is grassy, earthy, and slightly bitter, so vendors often add sugar, coconut water, or mung bean to make it sweeter and creamier.

For travelers, rau má is more than a refreshing drink. It is an everyday part of Vietnamese food culture, commonly found at local juice stalls, markets, and casual drink shops.

What Is Pennywort Juice?

Pennywort juice is a Vietnamese drink made from fresh pennywort leaves, known locally as rau má. The plant is scientifically known as Centella asiatica and is also commonly called gotu kola or Asiatic pennywort.

The fresh leaves are washed, blended with water, and strained to produce a vivid green drink. It is usually served cold with ice and can be sweetened to taste.

A basic glass of rau má typically contains:

• Fresh pennywort leaves

• Filtered water

• Sugar or sugar syrup

• Ice

Some versions include additional ingredients such as coconut water, mung bean paste, or condensed milk.

Unlike fruit juices, pennywort juice has a distinctly herbal character. Its natural flavor is more earthy and grassy than sweet, making it an interesting choice for travelers who want to try something beyond Vietnam's familiar coffee and fruit drinks.

What Does Pennywort Juice Taste Like?

Pennywort juice has a fresh, grassy, earthy, and slightly bitter taste.

If you've never tried it before, the flavor can be surprising. It may remind you of fresh green herbs, wheatgrass, or lightly brewed green tea. The natural bitterness becomes more noticeable when the drink is served without sugar.

Vietnamese vendors often balance this flavor with sweetness.

A typical glass may taste:

• Pure rau má: Earthy, grassy, and slightly bitter

• Sweetened rau má: Herbal with a mild sugary finish

• Rau má nước dừa: Lighter, sweeter, and more refreshing

• Rau má đậu xanh: Creamy, nutty, and much sweeter

If you're trying pennywort juice for the first time, a lightly sweetened version is an easy introduction.

What Is Rau Má?

Rau má is the Vietnamese name for pennywort, or Centella asiatica.

It is a small, low-growing green plant that thrives in warm and humid environments. The rounded leaves are commonly used in Vietnamese food and traditional herbal practices.

The plant has a long history across Southeast Asia and is particularly familiar in Vietnam. Fresh rau má can be found in local markets and is commonly turned into drinks.

Although rau má is sometimes described as a medicinal herb, travelers should think of pennywort juice primarily as a traditional Vietnamese beverage, rather than a medical treatment.

Its popularity comes from its fresh flavor, availability, and long-standing place in Vietnamese food culture.

How Is Vietnamese Pennywort Juice Made?

Making traditional rau má is relatively simple.

1. Fresh leaves are cleaned

Vendors wash the pennywort leaves thoroughly to remove soil and other impurities.

2. The leaves are blended

The fresh leaves are combined with chilled water and blended until they form a green liquid.

3. The mixture is strained

The blended leaves are passed through a strainer to separate the juice from the fibrous plant material.

4. Sweetener is added

Depending on the vendor and customer's preference, sugar or sugar syrup can be added.

5. The drink is served cold

The finished juice is poured over ice and served immediately.

Some modern drink shops use blenders and standardized recipes, while traditional stalls may prepare the drink in a much simpler way.

Popular Types of Pennywort Juice in Vietnam

One of the fun parts of trying rau má in Vietnam is discovering the different versions available.

Rau Má Nguyên Chất

Rau má nguyên chất means pure pennywort juice.

This is the simplest version, usually made from fresh leaves, water, and sometimes a small amount of sugar.

It has the strongest herbal flavor and is a good choice if you want to experience the natural taste of rau má.

Rau Má Đậu Xanh

Rau má đậu xanh combines pennywort juice with mung bean.

Cooked mung beans are blended into the drink, creating a thicker and creamier texture. Sugar or condensed milk may also be added.

The mung bean softens the bitterness of the pennywort, making this version particularly approachable for first-time drinkers.

Rau Má Nước Dừa

Rau má nước dừa combines pennywort with coconut water.

The naturally sweet and refreshing coconut water creates a lighter drink and works especially well in Vietnam's hot weather.

For travelers looking for something refreshing rather than dessert-like, this is a good option to try.

Why Is Pennywort Juice Popular in Vietnam?

Vietnam's tropical climate makes cold drinks an important part of everyday life.

Walk through a Vietnamese neighborhood on a hot afternoon and you'll find numerous drinks available from small street stalls, cafés, markets, and juice shops. Rau má fits naturally into this culture because the drink is made from fresh local ingredients and is easy to serve chilled.

Its popularity also comes from familiarity.

For many Vietnamese people, rau má is not an exotic wellness drink. It is simply a familiar beverage that has been enjoyed across generations.

You may see it served alongside other popular Vietnamese drinks such as:

• Vietnamese iced coffee

• Sugarcane juice

• Coconut water

• Fresh fruit smoothies

• Soy milk

• Lotus tea

• Artichoke tea

This makes rau má an interesting part of Vietnam's broader street-drink culture.

Is Pennywort Juice Healthy?

Rau má has traditionally been used in Vietnamese and other Southeast Asian herbal practices, where the plant is valued for its refreshing and cooling qualities.

Fresh pennywort also contains naturally occurring plant compounds and nutrients. However, the nutritional value of a glass varies depending on how it is prepared.

For example, a glass made primarily from fresh leaves and water is very different from one containing large amounts of sugar, condensed milk, or mung bean.

It is best to enjoy pennywort juice as a traditional beverage, rather than relying on it as a treatment for a health condition.

If you have a medical condition, take medication, or are considering concentrated pennywort supplements, speak with a qualified healthcare professional.
