What is betel nut chewing?

Betel nut chewing (Ăn trầu, nhai trầu) is a long-standing cultural practice in Vietnam, symbolizing social connection and tradition. It involves the combination of betel leaves, areca nuts, often accompanied by other ingredients to enhance the flavor and experience.

This practice not only serves as a mouth freshener but also holds significant social and ceremonial value, particularly in weddings and other important events. In Vietnam, the betel quid often includes a variety of additions such as chay bark (Indian mulberry), quach bark, cinnamon, and tobacco. 

Why do Vietnamese people chew betel?

Just as cheese is to the French or tea is to the British, betel chewing was once omnipresent among the Vietnamese, tracing back to the era of the Hùng kings, at the dawn of the nation. Betel was intricately tied to the beauty standards of ancient Vietnamese, particularly the practice of blackening teeth.

For women of the past, blackened teeth, reddened by betel chewing, were seen as a natural way to enhance beauty, complemented by red lips and rosy cheeks. Today, this tradition has faded, replaced by the modern ideal of white teeth, red lips achieved with lipstick, and pink cheeks with makeup. Chewing betel for hours slowly releases a red liquid that emits a pleasant fragrance and refreshes the breath.

The practice of blackening teeth was considered an art form and a way to preserve dental health. Betel chewing, which naturally darkened the teeth, also helped maintain strong and healthy teeth. This is why even today, in Vietnam, elders over 100 years old still often retain well-functioning teeth.

Betel chewing among the Tay and Muong women

Tay and Muong women always carry a betel pouch. These pouches are typically made of fabric, sewn into the shape of a chicken or a cylindrical tube with a round bottom, and cinched with a drawstring to tie around the waist when traveling. Betel chewing is always accompanied by slaked lime, an essential ingredient.

In the past, betel chewing was a way to enjoy the spicy fragrance of the betel leaf, the mild bitterness of the bark, the sweet crunch of the areca nut, and the warmth of the lime, all blending into a deep red hue.

Betel chewing in Vietnamese culture

• A symbol of marriage in Vietnam

As a symbol of the "beginning of the conversation," betel chewing holds both social and symbolic significance. During marriage and engagement ceremonies, betel and areca nuts are always included in the offering trays. It is said that the appearance of the areca nuts and betel leaves can predict the happiness and success of the couple.

In Vietnamese villages, trau cau (betel nut) is meticulously prepared by the elders, who gather on a straw mat adorned with the chữ Hỷ symbol (representing "joyful events") to collaboratively craft the intricately shaped phoenix betel nuts.

With skillful hands, they cut the betel leaves into phoenix wing shapes, ensuring that all 100 areca nuts are uniform and identical. Discover the unique customs, traditions, and trends of weddings in Vietnam.

Traditionally, when a family marries off their daughter, areca nuts and betel leaves are gifted to neighbors and extended family members as a gesture of sharing and gratitude. Even if some do not consume them, these offerings are always graciously accepted out of respect for tradition.

• Offerings of respect and veneration to ancestors

On family altars, betel and areca nuts are indispensable offerings, symbolizing the respect of current generations for their ancestors. During Tết (Vietnamese New Year), trays of betel and areca nuts are placed on altars to attract prosperity and luck for the coming year.

The areca nuts must be carefully chosen—large, green, and fresh—while the betel leaves should be intact and vibrant green. Betel is also used to welcome visitors who come to present their Tet (New Year) wishes. For more information, please read: A Traveler's Handbook for Tet Holiday in 2025.

For ancestral offerings, the areca nuts and betel leaves must be fresh and well-formed, reflecting the care and respect devoted to this tradition.

Betel chewing as seen by the French

The custom of betel chewing was widespread among the Vietnamese, as described by Charles Edouard Hocquard in his work Une campagne au Tonkin. According to him, nearly all Vietnamese people regularly consumed betel, making it an integral part of their lifestyle. Women of high society and officials often traveled with a servant carrying a copper spittoon and a finely crafted box containing everything needed to prepare betel. This tradition showcased a certain cultural refinement.

At the time, betel consumption was ubiquitous, not only in Tonkin (modern-day northern Vietnam) but throughout Indochina. Everyone—from laborers to children, women, and the elderly—chewed betel throughout the day, except during meals or sleep. Even the elderly, whose fragile teeth could no longer chew areca nuts, continued the practice by grinding the nuts in small copper mortars.

Betel also played a central role in social and commercial interactions. No exchange between two merchants began without the offering of a betel chew, a gesture symbolizing hospitality and mutual respect.

How to consume betel and areca nut

The term "chewing betel" (nhai trầu in Vietnamese) is a simplified expression, as this practice involves the combination of several ingredients. Traditionally, a betel quid consists of multiple elements: the betel leaf, the areca nut, tree bark, and slaked lime. Some people also add a few strands of tobacco or thuốc lào (a type of snuff), which they chew with the quid. This addition enhances and prolongs the characteristic flavor of betel chewing while leaving a unique aroma on the teeth.

The Preparation Process

French military doctor Charles Edouard Hocquard described the preparation of betel with curiosity and detail in his book. Observing his workers (cu-li) preparing a betel quid (têm trầu in Vietnamese), he noted that the process was meticulous and required skill and patience.

He described a man sitting near him, carefully preparing a quid. The man had his tools on his lap: a knife to cut the areca nut, a large needle, and a bag containing slaked lime in liquid form.

Here are the steps Hocquard observed:

• The man took a betel leaf in his left hand.
• He dipped the needle into the bag of lime and applied it several times to the leaf.
• Next, he took a dried areca nut and a red root from his belt and cut a small piece of each.
• These pieces were placed in the center of the leaf, which he then rolled into a small bundle about the size of a finger.

Thus, the betel quid was ready to chew. Hocquard highlighted the precision and care required for this preparation, reflecting its cultural importance and the skill involved in this daily Vietnamese ritual.

What does betel taste like?

Chewing betel offers a rather pleasant experience, characterized by a refreshing sensation and an appetite-suppressing effect. This was especially valued by ancient Vietnamese when food was scarce.

However, excessive consumption can have side effects, such as lip swelling, staining teeth a reddish-brown color, and damaging dental enamel. Despite these drawbacks, the Vietnamese find the practice highly enjoyable, attesting to its deep cultural roots and lasting appeal.

The Flavor Components

A betel quid combines four ingredients:

• Areca nut: Sweet taste
• Betel leaf: Spicy taste
• Root: Bitter taste
• Slaked lime: Warm taste

In Short

Today, betel chewing is no longer as common in Vietnam as it once was. It is now reserved for special and significant occasions. Although this tradition is in decline, betel chewing remains a valuable and distinctive cultural element in Vietnam and other Southeast Asian countries.
