The first time I visited a Vietnamese café during a hot summer afternoon, I noticed nearly every table had a tall glass of bright green juice instead of soda or iced tea.
Curious, I ordered one.
The drink arrived ice cold with a vibrant green color that immediately stood out. After the first sip, I understood why it was so popular. It tasted incredibly fresh, lightly herbal, naturally earthy, and surprisingly refreshing without being overly sweet.
That drink was Rau Ma, also known as Vietnamese pennywort juice.
Unlike sugary bottled beverages, Rau Ma offers a clean, refreshing flavor that’s both simple and satisfying. It’s made by blending fresh pennywort leaves with water, then straining and lightly sweetening the juice before serving over plenty of ice.
After making it at home several times, I discovered that the secret isn’t adding more ingredients. It’s using fresh pennywort, blending it thoroughly, and balancing the natural herbal flavor with just the right amount of sweetness.
This Rau Ma Recipe recreates the authentic Vietnamese drink using fresh ingredients and easy techniques, making it perfect for warm afternoons, healthy breakfasts, or whenever you need a naturally refreshing beverage.
What Is Rau Ma?
Rau Ma is a traditional Vietnamese herbal drink made from fresh pennywort leaves, water, and a small amount of sugar.
Pennywort is a leafy green herb widely enjoyed throughout Vietnam and other parts of Southeast Asia. The leaves are blended with water until smooth, then strained to create a refreshing green juice that’s served chilled over ice.
Unlike smoothies, Rau Ma has a thinner consistency and a clean, refreshing finish. Some modern variations include coconut water, pandan, mung beans, or fresh fruit, but the classic version remains incredibly simple.
One reason this Rau Ma Recipe has remained popular for generations is its refreshing taste and easy preparation.

How to Make Rau Ma Recipe
Although this drink is incredibly simple, a few techniques will help you achieve the smooth, refreshing texture found in Vietnamese cafés.
Step 1 – Wash the Pennywort Thoroughly
Place the pennywort leaves into a large bowl of cold water and gently swish them around to remove any dirt or grit.
Lift the leaves out of the water rather than pouring them through a strainer, allowing any sand to remain at the bottom of the bowl. Repeat this process two or three times until the water stays clear.
Finally, rinse the leaves under cool running water and drain well. Clean leaves are essential for producing a fresh-tasting drink without any unwanted grit.

Step 2 – Trim and Prepare the Leaves
Remove any thick stems, damaged leaves, or yellow pieces before blending.
Although tender stems can be used, removing older, woody stems creates a smoother juice with a cleaner flavor. Roughly chop the leaves into smaller pieces if necessary to help them blend more easily.
Preparing the pennywort properly also reduces strain on the blender and produces a more even consistency.

Step 3 – Blend the Ingredients
Add the cleaned pennywort leaves to a high-speed blender along with the cold water and granulated sugar.
Blend on high speed for 1 to 2 minutes until the leaves are completely broken down and the mixture becomes a smooth, vibrant green liquid.
Blending thoroughly extracts as much flavor and color as possible from the fresh herbs while creating the refreshing base for the drink.

Step 4 – Strain the Juice
Place a fine-mesh sieve or cheesecloth over a large pitcher or bowl.
Slowly pour the blended mixture through the strainer, pressing gently with the back of a spoon to extract as much liquid as possible.
Discard the remaining pulp once most of the juice has been extracted. Straining gives Rau Ma its smooth, refreshing texture that’s characteristic of authentic Vietnamese cafés.

Step 5 – Taste and Adjust the Sweetness
After straining the juice, taste it before serving.
If you prefer a sweeter drink, stir in an additional teaspoon or two of sugar until it dissolves completely. If the herbal flavor feels too strong, add a little more cold water to soften it without losing its refreshing character.
Taking a moment to adjust the sweetness ensures the drink matches your personal preference while keeping the authentic Vietnamese flavor intact.

Step 6 – Chill the Juice
Transfer the strained juice to a pitcher and refrigerate for 30 to 60 minutes before serving.
Serving Rau Ma thoroughly chilled enhances its naturally refreshing taste and allows the flavors to blend together. Although you can drink it immediately, chilling it first creates a smoother and more enjoyable experience.
A cold pitcher of Rau Ma is especially refreshing on warm summer days.

Step 7 – Pour Over Ice
Fill tall serving glasses with plenty of ice cubes.
Slowly pour the chilled Rau Ma over the ice until each glass is nearly full. The ice keeps the drink crisp and refreshing without changing its beautiful vibrant green color.
For an even colder drink, use crushed ice instead of regular cubes.

Step 8 – Garnish and Serve
Garnish each glass with a fresh mint sprig or a small lime wedge if desired.
Serve immediately while the juice is cold and vibrant. The clean herbal aroma, refreshing flavor, and naturally bright green color make this drink both visually appealing and incredibly satisfying.
Enjoy it as a refreshing afternoon beverage, alongside light meals, or whenever you want a naturally cooling homemade drink.
