Many locals refer to nuoc sam as “grass jelly drink” in English due to the plant’s appearance and the fact that concentrated forms can be used to make herbal jelly desserts.
The preparation process involves simmering dried Chinese mesona leaves with pandan leaves to extract their beneficial compounds. Rock sugar provides natural sweetness while lotus seeds or other medicinal herbs may be added for enhanced health benefits. Street vendors throughout Vietnam typically serve nuoc sam over ice garnished with a squeeze of kumquat or calamansi juice to brighten the flavor.
Unlike Western teas which often focus solely on taste nuoc sam emphasizes medicinal properties alongside its pleasant flavor profile. Traditional Vietnamese medicine attributes cooling properties to this herbal tea making it particularly popular during hot summer months. The drink supposedly helps balance the body’s internal temperature providing relief from heat-related discomfort.
Beyond its cooling effects nuoc sam is believed to aid digestion reduce inflammation and help detoxify the body.

For many Vietnamese people nuoc sam represents the perfect harmony between delicious refreshment and natural wellness.
Health Benefits Of Nuoc Sam
Nuoc sam offers many evidence-based health benefits that have made it a staple in Vietnamese traditional medicine for centuries. This herbal tea combines several powerful plant compounds that work synergistically to promote wellness throughout the body.
Digestive Support
Chinese mesona, the primary ingredient in nuoc sam, contains natural compounds that soothe the digestive tract. Regular consumption may help alleviate common digestive issues such as bloating, indigestion, and stomach discomfort. The cooling properties of this herbal drink also make it particularly effective for calming an upset stomach during hot weather when digestive problems often intensify.
Natural Cooling Properties
The remarkable cooling effect of nuoc sam isn’t just a sensation but a legitimate physiological response. Traditional Vietnamese medicine classifies herbs according to their heating or cooling properties within the body. Chinese mesona falls firmly in the cooling category, making nuoc sam an ideal remedy during hot weather or when experiencing excess internal heat manifesting as sore throat, fever, or inflammation.
Detoxification Benefits
Research suggests that nuoc sam supports the body’s natural detoxification processes. The phenolic compounds found in Chinese mesona help promote liver function which assists in filtering toxins from the bloodstream. This cleansing action may contribute to improved overall health and increased energy levels when nuoc sam is consumed regularly.
Anti-inflammatory Effects
Modern scientific studies have identified important anti-inflammatory properties in the compounds found in Chinese mesona. These anti-inflammatory effects may help reduce swelling, ease joint pain, and potentially benefit those with inflammatory conditions. The natural plant compounds work by inhibiting inflammatory pathways in the body without the side effects associated with pharmaceutical anti-inflammatories.
Antioxidant Protection
Nuoc sam contains potent antioxidants that help neutralize harmful free radicals in the body. These protective compounds may reduce oxidative stress, which is linked to premature aging and various chronic diseases. Regular consumption potentially offers cellular protection against environmental damage and internal stressors.
| Benefit Category | Key Compounds | Potential Effects |
|---|---|---|
| Digestive | Polysaccharides | Soothing digestive tract, reducing bloating |
| Cooling | Menthol-like compounds | Reducing body heat, relieving throat irritation |
| Detoxification | Phenolic compounds | Supporting liver function, filtering toxins |
| Anti-inflammatory | Flavonoids | Reducing inflammation, easing joint pain |
| Antioxidant | Polyphenols | Neutralizing free radicals, cellular protection |
Ingredients For Nuoc Sam
Creating authentic nuoc sam requires exact ingredients that contribute to its distinctive taste and medicinal properties. Here’s everything you’ll need to prepare this traditional Vietnamese herbal tea at home.
Fresh Herbs And Roots
- 1 oz (30g) dried Chinese mesona leaves (also called grass jelly herb)
- 3-4 pandan leaves, knotted
- 2 inches fresh ginger root, sliced
- 1 small handful of dried lotus seeds (optional)
- 8 cups water
- 1 tablespoon dried chrysanthemum flowers (optional for added cooling properties)
- Fresh mint leaves for garnish
- Ice cubes for serving
Sweeteners And Flavorings
- 1/2 cup rock sugar (adjust according to taste preference)
- 2-3 fresh calamansi or kumquat fruits
- 1 tablespoon honey (optional alternative sweetener)
- 1/2 teaspoon vanilla extract (optional for added aromatic flavor)
- Pinch of salt (enhances overall flavor profile)
The quality of these ingredients directly impacts the therapeutic benefits of your nuoc sam. Fresh herbs yield the most potent flavor and medicinal properties. Many Vietnamese households keep these ingredients on hand during summer months for quick preparation when the weather turns particularly hot.
Equipment Needed
Preparing nuoc sam at home requires minimal specialized equipment but does need a few essential kitchen tools to ensure proper extraction of flavors and medicinal properties from the Chinese mesona leaves and other ingredients. Here’s what you’ll need to make this traditional Vietnamese herbal tea:
- Large pot or saucepan (4-6 quart capacity) for simmering the herbs
- Fine mesh strainer to filter out the herbs and plant material
- Cheesecloth for additional filtering to achieve a clear liquid
- Large mixing bowl to collect the strained tea
- Wooden spoon for stirring during the simmering process
- Measuring cups and spoons for accurate ingredient proportions
- Glass bottles or jars with tight-fitting lids for storing prepared nuoc sam
- Ice cube trays if you plan to serve the drink cold
- Glass serving cups preferably clear to showcase the rich amber color
For best results, use stainless steel or ceramic cookware rather than aluminum when preparing nuoc sam. Metal utensils might affect the delicate flavors of the herbs. Your glass storage containers should be thoroughly sanitized before use to extend the shelf life of your freshly made tea. When serving nuoc sam to guests, tall clear glasses allow them to appreciate both the distinctive color and any additional garnishes you might add.
How To Make Nuoc Sam
Creating authentic nuoc sam at home allows you to enjoy this traditional Vietnamese herbal tea whenever you desire. The process involves three main steps: preparing the herbs, brewing the tea, and sweetening before serving.
Preparing The Herbs
Begin by thoroughly rinsing the dried Chinese mesona leaves under cold water to remove any dust or debris. Place the clean leaves in a bowl and soak them in room temperature water for about 15 minutes to rehydrate them properly. Wash the pandan leaves and tie them into knots to release more flavor during brewing. If using fresh ginger, peel and slice it into thin pieces to maximize the extraction of its aromatic compounds. For optional ingredients like dried lotus seeds or chrysanthemum flowers, rinse them briefly under cold water. Pat all herbs dry with a clean kitchen towel before proceeding to the brewing stage. Proper preparation of these herbs ensures that your nuoc sam will have the authentic earthy flavor and medicinal benefits that make this drink so cherished in Vietnamese culture.
Brewing The Tea
Pour 8 cups of filtered water into a large stainless steel or ceramic pot and bring it to a gentle boil over medium heat. Add the prepared Chinese mesona leaves, knotted pandan leaves, and sliced ginger to the pot. Reduce the heat to low and allow the mixture to simmer uncovered for about 30-40 minutes until the liquid develops a rich amber color. Stir occasionally to ensure even extraction of flavors from all ingredients. The brewing process should never reach a rolling boil as this can affect the delicate flavors of the herbs. Your kitchen will fill with an earthy aromatic scent when the tea reaches optimal strength. Remove the pot from heat and let the tea steep for an additional 10-15 minutes with the lid on. This patience during brewing extracts the maximum health benefits and flavor from the herbs.
Sweetening And Serving
Strain the brewed tea through a fine mesh strainer lined with cheesecloth into a large heat-resistant container. Add rock sugar while the tea is still warm, stirring until completely dissolved. The amount of sugar can be adjusted between 1/3 to 1/2 cup depending on your sweetness preference. Allow the sweetened tea to cool completely before transferring it to the refrigerator to chill for at least 2 hours. Fill glasses with ice cubes and pour the chilled nuoc sam over the ice. Squeeze fresh calamansi or kumquat juice into each glass for a refreshing citrus note that balances the earthy flavor of the tea. Garnish with a thin slice of kumquat or a sprig of mint for an appealing presentation. Nuoc sam can be stored in the refrigerator for up to 5 days in an airtight glass container, making it a convenient refreshment during hot summer days when its cooling properties are most appreciated.
Variations Of Traditional Nuoc Sam
While the classic nuoc sam recipe remains beloved across Vietnam, creative variations have emerged that adapt this traditional herbal tea to different tastes and preferences. These adaptations maintain the core health benefits while introducing new flavor profiles and serving methods.
Iced Nuoc Sam
Traditional nuoc sam transforms into a particularly refreshing summer treat when served over ice. You can prepare this cooling variation by chilling your freshly brewed nuoc sam completely before pouring it over a glass filled with ice cubes. Many vendors add extra calamansi or kumquat juice to enhance the citrus notes that complement the earthy base flavor. Some modern interpretations include fresh mint leaves as a garnish, providing an aromatic dimension that brightens the drink further. For special occasions, consider serving iced nuoc sam with grass jelly cubes at the bottom of the glass, creating a delightful textural contrast between the chewy jelly and the refreshing liquid. This version has become increasingly popular at Vietnamese cafés where it’s often presented in tall glasses with colorful straws for both visual appeal and functionality.
Nuoc Sam With Coconut Water
Blending nuoc sam with fresh coconut water creates a tropical twist that elevates the drink’s hydrating properties. You should start with a batch of concentrated nuoc sam tea, brewing it slightly stronger than normal to stand up against the coconut water’s subtle sweetness. Mix equal parts cooled nuoc sam and fresh coconut water in a pitcher, adjusting the ratio to suit your preference. Fresh coconut water adds electrolytes and minerals that complement the herbal benefits of nuoc sam, making this variation especially effective for rehydration during hot weather. The natural sweetness of coconut water often reduces the need for additional sugar, creating a lighter version that appeals to health-conscious drinkers. Street vendors in coastal regions of Vietnam frequently offer this variation, serving it directly in young coconuts with the top removed for an authentic presentation. This refreshing combination works wonderfully as a post-exercise recovery drink that delivers both flavor and nutritional benefits.
Storage And Make-Ahead Tips
Nuoc sam maintains its quality exceptionally well when stored properly. Refrigerate any leftover tea in an airtight glass container for up to 5 days without losing its medicinal properties or flavor profile. Glass containers are preferable as they don’t absorb the strong herbal flavors or release chemicals into the tea.
You can prepare a large batch of nuoc sam base during the weekend to enjoy throughout the week. Simply brew a double or triple portion of the tea following the standard recipe then store it unsweetened. This preservation method works best as sugar can sometimes alter the flavor during extended storage.
For the freshest taste experience add your sweeteners sugar citrus juice and ice only when ready to serve. The concentrated tea base actually develops more complex flavors after sitting for 24 hours as the herbs continue to infuse.
Freezing portions of nuoc sam in ice cube trays creates convenient flavor bombs for future use. These frozen cubes can be added to plain water for a quick refreshing drink or used in smoothies for added health benefits.
Room temperature storage is not recommended for nuoc sam as the natural compounds may deteriorate quickly and bacterial growth becomes a concern after just a few hours. Always keep your prepared tea chilled especially during hot summer months when this cooling beverage is most popular.
Serving Suggestions
Nuoc sam truly shines when presented thoughtfully with complementary foods and in the right settings. Traditional Vietnamese serving customs enhance both the flavor experience and the visual appeal of this medicinal tea.
Pour nuoc sam over ice in tall glasses for immediate refreshment on hot days. The contrast between the dark amber tea and ice cubes creates an inviting presentation that promises relief from summer heat. Add a thin slice of lime or kumquat on the rim for both decoration and an extra burst of citrus aroma.
Serve alongside Vietnamese street food favorites like banh mi or spring rolls to create an authentic experience. The cooling properties of nuoc sam balance perfectly with the savory and sometimes spicy elements of these popular dishes. This pairing represents a typical Vietnamese street food experience that locals enjoy regularly.
Offer nuoc sam as part of a traditional Vietnamese dessert course with che (sweet soups) or fresh tropical fruits. The slightly earthy flavor of the tea complements the sweetness of desserts without overwhelming them. Many Vietnamese households serve this combination after dinner especially during family gatherings.
Create a self-serve nuoc sam station at summer gatherings with various garnishes like mint sprigs lemongrass straws and citrus wedges. Allow guests to customize their drinks with different levels of sweetness and acidity. This interactive approach makes nuoc sam a conversation starter at social events.
Consider serving nuoc sam in clear glass pitchers or dispensers for larger gatherings to showcase its rich color. The visual appeal of the tea becomes part of your table decoration while keeping guests refreshed. Glass containers maintain the temperature better than plastic alternatives.
Pair with light Vietnamese appetizers like goi cuon (fresh spring rolls) for an afternoon tea gathering with a Vietnamese twist. The refreshing qualities of both the rolls and the tea create a light yet satisfying snack combination. This pairing works particularly well for casual social occasions or as a prelude to a larger meal.
When To Drink Nuoc Sam

During Hot Weather

The Chinese mesona in nuoc sam activates your body’s natural cooling mechanisms without the sugar crash associated with commercial cold drinks.
For Digestive Support
Consider drinking nuoc sam about 30 minutes after heavy meals to aid digestion. The gentle herbs work to soothe your digestive tract and reduce feelings of bloating or discomfort. Many Vietnamese restaurants offer nuoc sam as a post-meal beverage precisely for this reason. Morning consumption on an empty stomach may also help stimulate digestive function for the day ahead.
For Detoxification
Early morning represents the optimal time to drink nuoc sam for detoxification purposes. Your body naturally detoxifies overnight and continues this process upon waking.

Many Vietnamese families increase their consumption of nuoc sam during the transition from summer to fall or winter to spring. The adaptogenic qualities of the herbs help your body adjust to environmental shifts.
As a Caffeine Alternative
Afternoon energy slumps typically send people reaching for caffeine. Nuoc sam offers a refreshing alternative that provides gentle energy without disrupting sleep patterns.

This perspective doesn’t separate nutrition from healing but sees them as interconnected aspects of maintaining health.
