Plantain, or Plantago major, is a common weed often found on roadsides, in gardens, and in areas close to human habitation in Vietnam. This hardy plant is easily recognizable by its lush, thick leaves with prominent parallel veins and short stems. Typically growing to a height of just 10 to 15 cm, its vitality is truly remarkable.
Plantain is incredibly resilient, often growing interspersed with other types of weeds and thriving in various soil types. Beyond its familiarity, this weed offers numerous benefits in cuisine and traditional medicine, becoming an integral part of the daily diet of Vietnamese people.
Plantain, a vigorous weed, thrives and grows robustly throughout Vietnam. This herb typically grows in moist soil and is commonly found on roadsides, lawns, fields, and even forgotten garden corners. Despite favoring low light and humidity, plantain exhibits remarkable adaptability, surviving and thriving in arid conditions.
While many may associate plantain primarily with its heat-clearing and detoxifying properties through infused drinks, this weed offers a plethora of delicious and nutritious culinary options.
In many Asian countries, young plantain leaves are used as a fresh vegetable in meals. In Japan, plantain leaves are often eaten raw and used in traditional seafood soups. In South America and Native American cultures, young leaves are chosen for salads, while older leaves are typically stewed or cooked with meat.
In Vietnam, young plantain leaves are creatively prepared in various dishes such as soups, stir-fries, or herbal salads, not only providing a delightful flavor but also contributing to the consumers’ well-being.
Soup made with plantain leaves and minced meat, shrimp, or crab is a familiar dish from this herb. With its natural sweet and cool taste, the soup is not only refreshing but also perfect for hot summer days. Additionally, plantain leaves can be stir-fried with garlic, resulting in a simple yet delicious dish that easily satisfies diners.
For those who appreciate folklore-inspired cuisine, plantain is used to make herbal salads combined with other fresh herbs, adding a unique freshness and flavor to the meal.
It’s not just the leaves that are valuable; plantain seeds are also useful in cuisine, especially in desserts. When soaked, the seeds swell up like basil seeds and can be used to make refreshing drinks or cooked into a sweet porridge, creating nutritious and intriguing dishes.
Beyond its culinary value, plantain is highly regarded in traditional medicine. It is considered more than just a roadside weed but a precious herb that confers numerous health benefits.

According to master physician Bui Dac Sang from the Hanoi Oriental Medicine Association, plantain leaves are rich in calcium and contain various other minerals. Every 100g of plantain leaves provide a significant amount of vitamin A, equivalent to that found in carrots.

The seeds also contain valuable components such as plantagenetic acid and choline.
